MATLAB: If we directly give the input instead of giving color histogram block what will happen

color histogramImage Processing Toolbox

What would be output we obtain after passing the color histogram block. What will happen if i did not use it. (or) whats the role of color histogram?

hi, if you pass color histogram through what ? what system?

The role of color histogram is that it compute the Probability density function of each channel of the m by n by 3 image/snapshot.

Histogram is displaying the distribution of data. Color histogram shows distribution for each band.

    %Split into RGB Channels
    Red = image(:,:,1);
    Green = image(:,:,2);
    Blue = image(:,:,3);
    %Get histValues for each channel
    [yRed, x] = imhist(Red);
    [yGreen, x] = imhist(Green);
    [yBlue, x] = imhist(Blue);
    %Plot them together in one plot
    plot(x, yRed, 'Red', x, yGreen, 'Green', x, yBlue, 'Blue');

MATLAB: What is meant by color histogram? whats the difference between normal histogram and color histogram

Color histogram : it computes the histogram for each channel of the image, like per example a RGB image, C.H computes hists for R G and B matrices(images).

normal histgram : as i think , it computes a histogram of Gray-Scale image ( single 2D signal ) ,

I am sure there are many submissions in the FileExchange for computing Color Histograms , here is an example by Jeff Mather :
