OpenCV实现USM锐化 [转]http://www.programdevelop.com/4964391/ USM (Unsharp masking) is a common operation of image processing. From the Internet search a bit, there are basically three different ways. Only 2 lines of code, there are hundreds of the most co…
分支判断的语句一般来说是不太适合进行SSE优化的,因为他会破坏代码的并行性,但是也不是所有的都是这样的,在合适的场景中运用SSE还是能对分支预测进行一定的优化的,我们这里以某一个算法的部分代码为例进行讲解. 在某一个版本的USM锐化算法中有这样的一段代码: int IM_UnsharpMask(unsigned char *Src, unsigned char *Dest, int Width, int Height, int Stride, int Radius, int Amount, in…
