Edit Question
Title
Body
I understand that the seven hu invariant moments are for translation, rotation, and scale change of the object, in order to recognize the object independently these factors. That's why I used the function "moments" from OpenCV to extract the central moments, then I used the function HuMoments to get the seven invariant moments of the following binarized image : My first question is regarding the use of the function "moments" from OpenCV. The second parameter is "binaryImage" and I set it true, because it's a binary image, is it ok? My second doubt is regarding the output of the function "HuMoments": the seven hu invariant moments. I don't understand this data. what data is related to rotation, what for translation and what for scale change?. Many thanks!, cheers!
