Hi everyone, I'm doing some research in Content Based Image Retrieval (CBIR) and a certain part of it involves the extraction of three feature vectors- Color Histogram, Gist, and Zernike Moment.Firstly, i'm trying to implement the process followed in a research paper. The link is given below. Please jump to *Section 3.2*, "Each image is represented by 3 vetors.." Now i have found various scripts on the internet which (perhaps) may do the job but being relatively new to the field of image processing and a beginner in MATLAB, i'm pretty much overwhelmed. I would really, really appreciate it if someone could explain to me in simple terms, *how to exactly implement the process given in section 3.2 and extract the vectors*. Thanks in advance.
