      For example, a PNG image supporting alpha channel scan can have its background changed without inferring with the rest of its appearance. It supports up to 48-bit true color and 16-bit grayscale imagery, and doesn’t deteriorate the image quality if it’s re-saved or formatted.

      The most critical feature of our project is being able to correctly compare the image of the textbook taken from raspberry pi and the image provided by the user. We are going to use the OpenCV library of python. Using this, we are going to convert our original image from the BGR color space to grayscale using the code COLOR_BGR2GRAY.

      Example: My negative picture would try to use the grayscale image, and not the original photo. The most rewarding part was slowly understanding how pictures are modified in a digital space. I know that seems very simple, but it never occurred to me before how different digital art is when compared to a physical sketch or painting."

      Color images can be stored in a similar fashion to a grayscale image. Instead of one number (0-255) per pixel, one stores three numbers per pixel – these three numbers denote the “amount” of red, “amount” of green, and “amount” of blue in each pixel. These three numbers can be used to depict a wide range of colors.

      You will notice that it is able to take many more grayscale images than color ones. This is because color images have a lot more information in them than grayscale images (see text on right). A 256x192 color image requires 256x192x3 (= 147, 456) bytes of data where as a grayscale image requires only 256x192 (= 49,152) bytes.

      Grayscale stretching is used to stretch the image intensities around an appropriate pixel value to make details more obvious for automatic detection. The grayscale stretching function used in our method is the sigmoid function (Gevrekci & Gunturk 2009), which has the following form:
