Research and implementation of enhancement algorithm for low-illumination image
低照度图像增强算法的研究与实现

Aiming at the darkness and low contrast of low illumination image, a low illumination image enhancement method, combining improved Histogram equalization and improved local contrast enhancement, was designed, which satisfied the needs of adjusting dynamic range and enhancing local contrast. Experiments show that the method will give observer a clearer global image with enough local contrast details in processing a low illumination image.
