The problem is that I can't understand how the "official" JPG->PGM convertitors work in terms of what value to assign to the final pixel (i guess, ...,I = rgb2gray( RGB ) converts the truecolor image RGB to the grayscale image I . The rgb2gray function converts RGB images to grayscale by eliminating the hue ... , The specific numbers in the question are from CCIR 601 (see the Wikipedia link below). If you convert RGB -> grayscale with slightly different ...,To convert a color from a colorspace based on a typical gamma-compressed (nonlinear) RGB color model to a grayscale representation of its luminance, the ... ,Average method is the most simple one. You just have to take the average of three colors. Since its an RGB image, so it means that you have add r with g with b and then divide it by 3 to get your desired grayscale image. ,This post is about working with a mixture of color and grayscale images and needing to transform them into a uniform format - all grayscale.
