This paper presents a novel local contrast enhancement algorithm based on local histogram modification. The computation of local contrast enhancement operators is usually slow though they produce better local contrast and details. We have addressed this issue by subtly designing a highly parallel algorithm, which could be easily implemented on Graphics Processing Units (GPU) to harvest high computational efficiency. Our method is fast and easy to use, and the experiment results show that the technique can produce good results on a variety of images.
