Feature extraction using Correlgoram : What does this means ?

Dear all,

I want to extract color features from a specific image. For this i tried to use the CBIR which i found via this link https://www.mathworks.com/matlabcentral/fileexchange/42008-content-based-image-retrieval. Among the proposed functions, I used ColorAutoCorrelogram which return a vector (1*64) with different values. Is that the feature vector which we calculate, this means that we extracted 64 features ? Is that right ?

I think you need to decide what your end goal is. Blindly calculating stuff doesn't help you. I don't fully understand a correlogram, so I can't tell you the differences with a GLCM, although it seems like they are very similar. If this is a project for a study assignment I highly suggest you talk to your professor.
