I am not getting the correct value for rblush in this code. here, red is a matrix consisting of only the r of rcb values of an image. If the value of red_pixel is greater than 200, i want to add the pixel values in rblush but im getting the wrong val

Since “red” is your red-channel image, you can directly find the pixel values that are greater than 200 and “rmean” in the follo...
