MATLAB: How to calculate intensity statistical features of gray scale images in MATLAB

image momentsImage Processing Toolbox

Please help me how to calculate first order intensity statistics features of gray scale images in MATLAB Thanks

Best Answer

Try these:

meanGrayLevel = mean2(grayImage)
stdDev = std2(grayImage)
v = var(grayImage(:))

MATLAB: Gray Color Intensity fill.

Note that AFR should hav one less row as well as column.

Probably, the simplest way to create your spray:

pdata = surf2patch(SL, h, zeros(size(h), AFR(1:end-1, :)));
figure;
patch(pdata, 'FaceColor', 'flat', 'EdgeColor', 'none');
colormap(grey);  %whatever colour map you want to use

surf2patch is used to convert your mesh into polygons that is then passed to patch.

MATLAB: Reduce to 64 gray levels in intensity

image_as_rgb = cat(3, YourGrayImage, YourGrayImage, YourGrayImage);
[image_as_ind, image_map] = rgb2ind(image_as_rgb, 64);
reduced_gray_image = ind2rgb(image_as_ind, image_map);
