HDR图片合成技术，是日本索尼公司图片处理算法。原理是放置两张曝光图片：一张暗和一张亮。经过合成处理生成一张更加接近现实美观的图片。此技术常用于改造照相机

opencv下编译通过，调用方法如下

/*iplImages图片数组，这里有两张：一张曝光亮的，一张曝光暗的*/

HDRMerger hdrMerge = hmCreateMerger(iplImages,length) 　　　　

/*对齐(解决抖动图片合成错位)，第2个参数是宽度，第3个参数是高度*/

hmAlign(hdrMerge, &nw, &nh, NProgressPercent) 　　

hmSetCurve(hdrMerge, CM_PD_BT_709) 　　

hmFusion(hdrMerge) 　　

hmFusionResult(hdrMerge,dst,0,0)

hmDestroyMerger(hdrMerge) 　　-HDR image synthesis, image processing algorithm of the Sony Corporation of Japan. The principle is to place two exposure picture: one dark and one bright. After the synthesis processing to generate a more realistic and beautiful pictures. This technology is commonly used to transform the camera opencv compiler, and call the method is as follows /* array of iplImages picture, there are two: an exposure of bright and a dark exposure of*/HDRMerger, hdrMerge = hmCreateMerger (iplImages, length)　/* alignment (to solve the jitter picture synthesis dislocation), the second parameter is the width, the third parameter height of*/hmAlign (hdrMerge, &　nw, &　nh to find, NProgressPercent)　hmSetCurve (hdrMerge, CM_PD_BT_709)　hmFusion (hdrMerge)　hmFusionResult ( hdrMerge, dst, 0,0)　hmDestroyMerger (hdrMerge)
