Grayscale Image Intensity Threshold
显示 更早的评论
I have a greyscale image where each pixel is given an intensity value with 0 being black and 1000 being white. (not actual values just given as an example. I want to set a threshold for intensioty values so that pixels above this threshold are turned red.
How do i do this?
I thought if i did a hist(intensity values, 1000) then i could simply set the threshold by the bins i wanted included. For example i could say only values that are in the last 200 bins are the ones i want turned to red. Is it possible to specify Matlab to manipulate individual bins?

You don't need to take the histogram. Simply threshold and set up the red, green, and blue color channels in a color image. See attached demo below in blue.
