Improvement of Histogram Equalization for Minimum Mean Brightness Error

چکیده
Abstract: This Research presents the image enhancing using a mean-separate histogram equalization method. It can preserve the original brightness to a certain extends. To provide maximum brightness preservation, . it separates the input image’s histogram into 2 based on input mean before equalizing them independently. The image initially is separated from 2 ,4 and 8 class by calculated threshold level and each class is histogram equalized to entire image, and gets lowest AMBE (AMBE : the absolute difference between input and output mean). The result found that AMBE gradually reduces when the separation is increased.

متن کاملMinimum mean brightness error bi-histogram equalization in contrast enhancement
Histogram equalization (HE) is widely used for contrast enhancement. However, it tends to change the brightness of an image and hence, not suitable for consumer electronic products, where preserving the original brightness is essential to avoid annoying artifacts. Bi-histogram equalization (BBHE) has been proposed and analyzed mathematically that it can preserve the original brightness to a cer...

Histogram equalization is a nonlinear technique for adjusting the contrast of an image using its histogram. It increases the brightness of a gray scale image which is different from the mean brightness of the original image. There are various types of Histogram equalization techniques like Histogram Equalization, Contrast Limited Adaptive Histogram Equalization, Brightness Preserving Bi Histogr...
