3.5.4 Problem in Histogram Equalization 1. This histogram equalization method does not take the mean brightness of an image into account. 35 2. The HE method may result in over enhancement and saturation art effects due to the stretching of the gray levels over the full gray level range. 3. HE can be found on the fact that the brightness of an image can be changed after the HE. 4. Nevertheless‚ HE is not commonly used in consumer electronics such as TV because it may significantly change the brightness
