OpenGL and OpenCV with python 2.7 - part 003.

If you have seen the last tutorial about OpenCV, then this tutorial comes to complete with one source code.
This source code will cut the background of webcam.
The webcam output is take by VideoCapture function.
This part of source code: np.zeros((1,65),np.float64) will return a new array of given shape and type, filled with zeros.
The result of this parts is used with function grabCut from cv2 python module.
This is the source code:

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
    ret, img = cap.read()
    #img = cv2.imread('test002.jpg')
    mask = np.zeros(img.shape[:2],np.uint8)

    bgdModel = np.zeros((1,65),np.float64)
    fgdModel = np.zeros((1,65),np.float64)

    rect = (50,50,450,290)
    cv2.grabCut(img,mask,rect,bgdModel,fgdModel,5,cv2.GC_INIT_WITH_RECT)

    mask2 = np.where((mask==2)|(mask==0),0,1).astype('uint8')
    img = img*mask2[:,:,np.newaxis]
    cv2.imshow('frame',img)
    if 0xFF & cv2.waitKey(5) == 27:
        break
cap.release()
cv2.destroyAllWindows()

The end result will be something like:

The python dizzy with clean instalation, is true !?

This will refer the python 2.7 working - but it can be extrapolated to other versions.
Many users have trouble installing python modules. The problem comes from old modules outdated or those who did not support.
I will present a few examples. I hope to come and support as necessary to remedy in time or exclusion through better solutions.
This is the main question for today: The python dizzy with clean instalation, is true !?
I don't think is a unwanted hacking of my python instalation using internet.
But I search and I saw many questions and erros over pip and Scripts folders.
I will deal just for this issue:
After I make one clean python 2.7 and all my python modules works well I used my windows to deal with some ssh software.
The next step I make it with python was to try to update with pip.
The strange think is with this files from Scripts folders:

12-Aug-16 06:41 PM 98,150 pyrsa-decrypt-bigfile.exe
12-Aug-16 06:41 PM 98,134 pyrsa-decrypt.exe
12-Aug-16 06:41 PM 98,150 pyrsa-encrypt-bigfile.exe
12-Aug-16 06:41 PM 98,134 pyrsa-encrypt.exe
12-Aug-16 06:41 PM 98,132 pyrsa-keygen.exe
12-Aug-16 06:41 PM 98,155 pyrsa-priv2pub.exe
12-Aug-16 06:41 PM 98,128 pyrsa-sign.exe
12-Aug-16 06:41 PM 98,132 pyrsa-verify.exe

and this file from same Script folder:

21-Jun-16 09:09 PM 0 python.exe

When I need to use pip I got errors.Then I try to fix with this:

pip install --upgrade ndg-httpsclient

and seem to be working now.
But I need to find from where come this file and why is this python file with:

C:\Python27\Scripts>python
Access is denied.

Maybe will be fix with a clean python instalation.
But the next step is and one of my concern is how to preserve this python instalation.
For example today the

pip update issue

come with many errors and this will be fixed.
Let's see how I fixed some of this.

First download Microsoft Visual C++ Compiler for Python 2.7.
This will fix this error:

error: Microsoft Visual C++ 9.0 is required. Get it from http://aka.ms/vcpython27

.

If you got this error: RuntimeError: Freetype library not found

raise RuntimeError('Freetype library not found')
RuntimeError: Freetype library not found

Also some python module has into cloud dizzy stuff.
For example the pycryptodome come with many features and working great.
Also some alternative is a bad solution.
It is hard to find a solution to the problem of leaving all these modules.
Any solutions?

The python module pycryptodome - part 001.

The tutorial for today come with this subject: python module pycryptodome.
According to the official website:

PyCryptodome is a self-contained Python package of low-level cryptographic primitives.
It supports Python 2.4 or newer, all Python 3 versions and PyPy.

official website.
Also this python module can be used with Windows and Linux (Ubuntu and Fedora distro linux).
I don't see anything about Mac OS - Apple OS Mac_OS - wikipedia.
First step of this tutorial:

C:\Python27\Scripts>pip install pycryptodome
Collecting pycryptodome

Most of resurces and features can be found here also can have some example at Matthew Green.
I will come with another tutorial about this python module.
Have a great day.

Hide your info with stepic python module.

I will show a funny way to put your info into one image and then show this info.
First you need one image. I used this image:

First need to use Python 2.7 with Image ( Pillow python module) and stepic python module.
... and follow the below steps:

C:\Python27>cd Scripts
C:\Python27\Scripts>pip install Image
C:\Python27\Scripts>pip install stepic
C:\Python27\Scripts>cd ..

C:\Python27>python
Python 2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

To encode and then to show the text from one image I used this python script:


import PIL
from PIL import Image
import stepic
im=Image.open("MonaLisa.jpg")
im1 = stepic.encode(im,'The smallest feline is a masterpiece.')
im1.save('test_encode.jpg','JPEG')
im.show()
im1.show()
decoding=stepic.decode(im1)
data_encode=decoding.decode()
print data_encode

The Python and antivirus Kaspersky antivirus.

The Kaspersky antivirus is very reserved versus python.

Even if the pip will try to install one module also any instance of numpy module has one replay over Kaspersky antivirus.

I try to start python shell and then import numpy after that I close the shell and I run it again. 
Update I try also help() / modules command under shell and more and randmon pyd file are blocked. This is strange because the pyd files are random.

See the result is how Kaspersky and python shell works together:

What do you think about that?

OpenCV with cutting video background.

This source code is a try to solve the video cutting background.
import cv2
from cv2 import *
import numpy as np
cap = cv2.VideoCapture("avi_test_001.avi")
while(True):
    ret, img = cap.read()
    mask = np.zeros(img.shape[:2],np.uint8)

    bgdModel = np.zeros((1,65),np.float64)
    fgdModel = np.zeros((1,65),np.float64)

    rect = (50,50,450,290)
    cv2.grabCut(img,mask,rect,bgdModel,fgdModel,5,cv2.GC_INIT_WITH_RECT)

    mask2 = np.where((mask==2)|(mask==0),0,1).astype('uint8')
    img = img*mask2[:,:,np.newaxis]
    cv2.imshow('frame',img)
    if 0xFF & cv2.waitKey(5) == 27:
        break
cap.release()
cv2.destroyAllWindows()

OpenGL and OpenCV with python 2.7 - part 002.

I deal today with opencv and I fix some of my errors.
One is this error I got with cv2.VideoCapture. When I  try to used with load video and createBackgroundSubtractorMOG2() i got this:

cv2.error:   C:\builds\master_PackSlaveAddon-win64-vc12-static\opencv\modules\highgui\src\window.cpp:281:  error: (-215) size.width<0 amp="" cv::imshow="" function="" i="" in="" size.height="">
You need also to have opencv_ffmpeg310.dll and opencv_ffmpeg310_64.dll into your Windows C:\Windows\System32, this will help me to play videos.
Now make sure you have the opencv version 3.1.0 because opencv come with some changes over python.
C:\Python27\python
Python 2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>import cv2
>>>print cv2.__version__
3.1.0

You can take some infos from about opencv python module - cv2 with:

>>>cv2.getBuildInformation()
...
>>>cv2.getCPUTickCount()
...
>>>print cv2.getNumberOfCPUs()
...
>>>print cv2.ocl.haveOpenCL()
True

You can also see some error by disable OpenCL:

>>>cv2.ocl.setUseOpenCL(False)
>>>print cv2.ocl.useOpenCL()
False

Now will show you how to use webcam gray and color , and play one video:
webcam color

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
    ret, frame = cap.read()
    cv2.imshow('frame',frame)
    if 0xFF & cv2.waitKey(5) == 27:
        break
cap.release()
cv2.destroyAllWindows()

webcam gray

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
    ret, frame = cap.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    cv2.imshow('frame',gray)
    if 0xFF & cv2.waitKey(5) == 27:
        break
cap.release()
cv2.destroyAllWindows()

play video

import cv2
from cv2 import *
capture = cv2.VideoCapture("avi_test_001.avi")
while True:
    ret, img = capture.read()
    cv2.imshow('some', img)
    if 0xFF & cv2.waitKey(5) == 27:
        break
cv2.destroyAllWindows()

OpenGL and OpenCV with python 2.7 - part 001.

First you need to know what version of python you use.
C:\Python27>python
Python 2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
You need also to download the OpenCV version 3.0 from here.
Then run the executable into your folder and get cv2.pyd file from \opencv\build\python\2.7\x64 and paste to \Python27\Lib\site-packages.
If you use then use 32 bit python version then use this path: \opencv\build\python\2.7\x86.
Use pip to install next python modules:
C:\Python27\Scripts>pip install PyOpenGL
...
C:\Python27\Scripts>pip install numpy
...
C:\Python27\Scripts>pip install matplotlib
...
Let's see how is working OpenGL:
C:\Python27>python
Python 2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import OpenGL
>>> import numpy
>>> import matplotlib
>>> import cv2
>>> from OpenGL import *
>>> from numpy import *
>>> from matplotlib import *
>>> from cv2 import *
You can also use dir(module) to see more. You can import all from GL, GLU and GLUT.
>>> dir(OpenGL)
['ALLOW_NUMPY_SCALARS', 'ARRAY_SIZE_CHECKING', 'CONTEXT_CHECKING', 'ERROR_CHECKING', 'ERROR_LOGGING', 'ERROR_ON_COPY', 'FORWARD_COMPATIBLE_ONLY', 'FULL_LOGGING', 'FormatHandler', 'MODULE_ANNOTATIONS', 'PlatformPlugin', 'SIZE_1_ARRAY_UNPACK', 'STORE_POINTERS', 'UNSIGNED_BYTE_IMAGES_AS_STRING', 'USE_ACCELERATE', 'WARN_ON_FORMAT_UNAVAILABLE', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '__path__', '__version__', '_bi', 'environ_key', 'os', 'plugins', 'sys', 'version']
>>> from OpenGL.GL import *
>>> from OpenGL.GLU import *
>>> from OpenGL.GLUT import *
>>> from OpenGL.WGL import *
If you are very good with python OpenGL module then you can import just like this example:
>>> from OpenGL.arrays import ArrayDatatype
>>> from OpenGL.GL import (GL_ARRAY_BUFFER, GL_COLOR_BUFFER_BIT,
... GL_COMPILE_STATUS, GL_FALSE, GL_FLOAT, GL_FRAGMENT_SHADER,
... GL_LINK_STATUS, GL_RENDERER, GL_SHADING_LANGUAGE_VERSION,
... GL_STATIC_DRAW, GL_TRIANGLES, GL_TRUE, GL_VENDOR, GL_VERSION,
... GL_VERTEX_SHADER, glAttachShader, glBindBuffer, glBindVertexArray,
... glBufferData, glClear, glClearColor, glCompileShader,
... glCreateProgram, glCreateShader, glDeleteProgram,
... glDeleteShader, glDrawArrays, glEnableVertexAttribArray,
... glGenBuffers, glGenVertexArrays, glGetAttribLocation,
... glGetProgramInfoLog, glGetProgramiv, glGetShaderInfoLog,
... glGetShaderiv, glGetString, glGetUniformLocation, glLinkProgram,
... glShaderSource, glUseProgram, glVertexAttribPointer)
Most of this OpenGL need to have a valid OpenGL rendering context.
For example you can test it with WGL ( WGL or Wiggle is an API between OpenGL and the windowing system interface of Microsoft Windows):
>>> import OpenGL
>>> from OpenGL import *
>>> from OpenGL import WGL
>>> print WGL.wglGetCurrentDC()
None
Now , let's see the OpenCV python module with s=one simple webcam python script:

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
while(True):
    ret, frame = cap.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
    cv2.imshow('frame',gray)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
cap.release()
cv2.destroyAllWindows()

This is result of my webcam:

News: The new python version 3.6.0.a1

I used the Windows x86-64 executable installer to install this version of python.
I set some settings and I start the install aplication.

I read all new changes and PEP 0498.
I take a look to see all python modules:

The new formatted string literals are a new kind of string literal, prefixed with 'f' this allow you to add contain replacement fields surrounded by curly braces.
I don't think the add Python start well, maybe need restart:

 >>> import crypt
Traceback (most recent call last):
  File "", line 1, in 
  File "C:\Python36\lib\crypt.py", line 3, in 
    import _crypt
ImportError: No module named '_crypt' 

Some of changes can be see at whatsnew.
You can read more and also download the new python released version 360a1 from here.
Very good work from development team, they make a great job.

Testing PyQt4 under Python 3.5.1.

Today I working well with python 3.5.1.
Most of my source code was wrote with python 2.7 and the next step was to using pip3.5 to update and upgrade some python modules.
I try to install PyQt4 with pip3.5 - not working.
So I used the old way: whl file from here.
That was good, most of the scripts was running.
The main problem was OpenGL and that will make errors when you try to use QtOpenGL.
The result of this seam to me the python 3.5.1 it's now without OpenGL features.
