okay let me show you the contents of this video which i am going to cover uh first i will explain the color space selection for watermarking then i will explain the proposed discrete wavelet transform based spread spectrum water marking for color images then i will explain the watermark embedding and watermark extraction algorithms then i will highlight some performance evaluation parameters after that i will explain the matlab code to implement the complete water marking process including uh both embedding and extraction of watermark and then i will do the result analysis in the last so letamp;#39;s go ahead but before going ahead i strongly uh recommend you to watch uh this my previous video which is about the wavelet based robust spread spectral water marking of gray scale images so this video is about the grayscale image watermarking so you can assume that this current video is the extension of this previous video so you can assume that this is the part one of this current
