图像的香农阈值选取-images Shannon threshold selection

用opencv写的手势识别代码,听说识别率还不错,当然得跟据自己的环境调一下阈值什么的.方法跟大多数的差不多,也是先滤波一遍,再从RGB转到HSV空间,设置阈值,再二值化成单色图,然后进行二次滤波把小杂点滤掉,再提取轮廓,在圆滑一下轮廓,最后用Hu矩和模板比较.

OpenCV 4下的图像任意角度的旋转 //待旋转的图像Img_old //返回的旋转后图像类型 IplImage* Img_tmp. //旋转的角度,单位度. //三种不同的方法.其中方法二没有完全测试,方法一可以满足大部分需要-OpenCV four images of arbitrary rotation angle// Image Rotation question Img_old// to return to the rotation after the image type IplImage* Img_tmp.// Rotation angle, unit degrees.// Three different ways. Two methods which do not fully test one way to meet the needs of the majority
