The article discusses a method to improve the appearance of images by enhancing their contrast. The researchers used a technique called Histogram Equalization to adjust the brightness levels in different parts of the image. This method helps to avoid issues like washed-out colors and false contours that can occur with traditional histogram equalization. The results show that this approach is effective for enhancing images taken in low light conditions. Overall, the histogram modification framework is a simple and efficient way to enhance image contrast in real-time systems.
