Comparison of the spatial resolution with the histogram equalization-obligated linear function on structural pixel position scheme

In the image´s structural pixel position schemes, the controlled approaches have been proposed. This paper compares the histogram equalization-obligated linear function with the spatial resolution on the structural pixel position scheme. The results show that the obligated linear function of the histogram equalization can maintain the pixel retention with lower span and lower covariance, in addition, gives higher peak signal to noise ratio. On the other side, the spatial resolution can improve the pixel distribution with almost full span, but gives similar complexity.
