Dear All. I'm Roy Nugroho from Indonesia. Now I do my final project about Super Resolution Reconstruction. In paper that i learn, there is a variable named D --> Decimation Matrix or Decimation Operator, or Downsample Matrix. Y(t) = DH(t)X(t) + N(t) X(t) = High Resolution Image size = (L^2 x 1) --> notation is in vector, size of image X is (L x L), and reshape to (

Hi, Am trying to use HSV in one of my applications to detect a face using skin color. Am developing a simple neural net for detecting the presence of a face in an image. First i resize all images into a 20x20 matrix. The i convert the image from RGB to HSV and then split it into H,S and V values/matrices. Do i use the H,S or V value as inputs into the net? Then how do histograms work exac...
