Sobel算子 Sobel算子用多项式计算来拟合导数计算,可以用OpenCv中的cvSobel函数或者EmguCv中的Image<TColor,TDepth>.Sobel方法来进行计算。需要注意的是,xorder和yorder中必须且只能有一个为非零值,即只能计算x方向或者y反向的导数;如果将方形滤波器的宽度设置为特殊值CV_SCHARR(-1),将使用Scharr滤波器代替Sobel滤波...
拉普拉斯算子可以用作边缘检测;可以用OpenCv中的cvLaplace函数或者EmguCv中的Image<TColor,TDepth>.Laplace方法来进行拉普拉斯变换。需要注意的是:OpenCv的文档有点小错误,apertureSize参数值不能为CV_SCHARR(-1)。 使用拉普拉斯变换的示例代码如下: 拉普拉斯算子 Canny算子 Canny算子也可以用作边缘检测;可以用OpenCv中的c...
First, we import OpenCV using the line, import cv2 Next, we read in the image, which in this case is, Boxes.png We then create a grayscale version of the image. In order to use the harris corner detection method, the grayscale image must be converted to float32 type. ...
答主比较懒。。我直接选择了用OpenCV来生成,官方教程在这里 -Face Morph Using OpenCV — C++ / Python | LearnOpenCV # 我首先选取了JAFFE中10张neutral face的图像,并通过dlib库(代码在github里 - ripser_data.py)生成68个特征点,之后手动添加了右耳、颈项、左肩、右肩的特征点,最后加入图片四个顶点及各边中...
