modify a numerical array or an image based on the given threshold

Question

I have an image, and would like to modify the image based on a given threshold. The function such as

binary = image > threshold 

will create a binary image. What I want is the image pixels will remain the same if it is higher than the threshold. Are there any convenient function to do that?

Answer 1

image[image < threshold] = 0

will clip every pixel below the threshold to 0 and will leave the rest intact
