The newly introduced Global Contrast Factor (GCF) corresponds closer to the human perception of contrast. GCF uses contrasts at various resolution levels in order to compute overall contrast.

What is global contrast?
The global contrast is defined as the average. local contrast of smaller image fractions.
What is the difference between global contrast and local contrast?
If using the global contrast method, the black block becomes the most salient object (middle), while the detection results of our local contrast is the red block (right), which gives more consistent result with the human visual attention.
What method can be used to improve the contrast of an image?
Global Histogram Equalization (GHE): This method spreads out the intensity values of an image's histogram to utilize the full range of possible values, enhancing the overall contrast.
What is the meaning of contrast in image processing?
The difference in brightness between light and dark areas of an image. Contrast determines the number of shades in the image. A low-contrast image (left) retains detail, but tends to lack dimension and look soft. An image with normal contrast (center) retains detail and dimension, and looks crisp.
