| 中文摘要: |
| 针对图像颜色传递典型算法Reinhard算法需对图像中的所有像素进行遍历搜索处理，计算量大、运算速度较慢这一问题，提出了一种基于GPU加速的图像颜色传递算法；利用可编程图形处理单元GPU并行计算和高速浮点计算特性，将Reinhard运算过程转化为GPU中的纹理图像渲染过程，使得Reinhard算法在GPU中加速执行．颜色传递效果对比结果表明，在取得较好的颜色传递效果的同时，该算法计算速度大大提高，且对大尺寸图像提速性能更好． |
| 英文摘要: |
| Reinhard algorithm is one of typical algorithms which transfers color information of one image to another. However, it needs a great deal of calculation and therefore the speed is very slow, for it needs searching each pixel of the picture. Consequently, a color transferring algorithm based on GPU(graphic processing unit)-acceleration is proposed, which maps Reinhard algorithm to texture-rendering on consumer-level graphics cards. The analytical results demonstrate that the proposed method not only achieves good effect but also speeds up its execution, especialy in big dimensional images. |
