Answer 1

In Python, you can take the help of the Image module to do this stuff.

For example -

import Image
picture = Image.open("/path/to/my/picture.jpg")
r,g,b = picture.getpixel( (0,0) )
print("Red: {0}, Green: {1}, Blue: {2}".format(r,g,b))

This above code will give you information about the pixel at (0,0)

import Image
picture = Image.open("/path/to/my/picture.jpg")

# Get the size of the image
width, height = picture.size()

# Process every pixel
for x in width:
    for y in height:
        # get pixel color
        current_color = picture.getpixel( (x,y) )

        # your main logic here to choose new color

        # put the new color on the pixel
        picture.putpixel( (x,y), new_color)
