This chart was created with MATLAB. |
The image was generated using the following MATLAB code, with help of external library plot2svc:
I = rgb2gray(imread('Unequalized_Hawkes_Bay_NZ.jpg')); h = hist(double(I(:)),0:255); map = cumsum(h)/prod(size(I)); J = 255*map(I+1); [h x]=hist(double(J(:)),0:255); map = cumsum(h)/prod(size(J)); figure(1) hold on bar(x, h, 'r'); plot(x, 30000*map, 'k') xlim([0 256]); ylim([0 31000]); plot2svg('Equalized Histogram.svg')
