Bresenham高效画线算法
- 画线的算法不少，但要作到高速、简单并不容易。斜率相乘法是最简单的方法之一，但计算每个点均要花费不少时间用于乘、除法运算；下面介绍的是Bresenham s高效画线算法，对每个点的坐标计算只要加、减法就能完成。-line drawing algorithm, but a lot to be done fast, simple is not easy. The slope is the most simple multiplication is one of the ways, but each p

NL-MEANS
- NL-MEANS图像去噪算法。 该算法对于灰度图像的高斯白噪声的去除效果极好，但是在计算时间上耗时较高。本程度对于256*256的灰度图像，约在30s以上。 运行，请输入“main”。-NL-means algorithm is a good way for grey image denoising on AWN, but it has high cost on the computation. The program here may cost beyond 30s for 256
