摘要
图像增强旨在改善和提高图像的显示质量,通过梯度进行增强是一种十分有效的方法。图形计算单元(GPU)因为其较高并行性和其特殊的结构特性,正被广泛地应用在算法加速和科学计算领域。为了提高学生对图像增强原理的理解,以及使学生掌握利用GPU进行算法实现的原理与过程,设计了基于GPU的图像增强实验。
The image enhancement aims to improve the display quality of images. It is a very effective method to enhance images by gradients. The GPU (graphic processing unit) is widely used in the fields of algorithm acceleration and scientific computation because of its high parallelism and its special structural characteristics. In order to improve the students' understanding of the principle of image enhancement, and help them to grasp the principle and process of using GPU to realize the algorithm, the image enhancement experiment based on GPU is designed.
