The histogram processing algorithm for vehicle camera image pixel contrast improving

In this paper, we propose the histogram processing algorithm for improving pixel contrast of vehicle camera image. The proposed the histogram processing algorithm was elimination to the vehicle image shake using motion compensation and motion estimation. And, algorithm was calculated the histogram of pixel values from each sub-image by dividing the image as the constant size areas in order to image enhancement. Also, it had enhancement to the image by adjusting the gradient. The proposed algorithm was evaluating the difference between of performance and time, image by applied to the IP, and were confirmed the image enhancement with removing of vehicle camera image shake. And it was obtained the reduction effect of the computation time by the calculated through histogram matching using the look-up table, and obtained the better restoration result for naturalness of the image with the lowest noise.
