CUDA Implementation of Histogram Stretching Function for Improving X-ray Image
View through CrossRef
This paper presents a method to improve the contrast of digital X-ray image using CUDA program on a GPU. The histogram is commonly used to get the statistical distribution of the contrast in image processing. To increase the visibility of the image in real time, we use the histogram stretching function. It is difficult to implement the function on a GPU because the CUDA program is due to handle the complex process to transfer the source data and the processed results between the memory of GPU and the host system. As a result, we show to operate the histogram stretching function quickly on GPU by the CUDA program.
