OpenCV - Distance Transformation. The distance transform operator generally takes binary images as inputs. In this operation, the gray level intensities of the points inside the foreground regions are changed to distance their respective distances from the closest 0 value (boundary). You can apply distance transform in OpenCV using the method ...

distanceTransformWithLabels() - distanceTransformWithLabels(src, distanceType, maskSize[, dst[, labels[, labelType]]]) -> dst, labels.

public static void distanceTransformWithLabels(Mat src, Mat dst, Mat labels, int distanceType, int maskSize) { distanceTransformWithLabels_1(src.

Jan 08, 2013 · Use the OpenCV function cv::filter2D in order to perform some laplacian filtering for image sharpening. Use the OpenCV function cv::distanceTransform in order to obtain the derived representation of a binary image, where the value of each pixel is replaced by its distance to the nearest background pixel. Use the OpenCV function cv::watershed in ...

从文档: OpenCV具有distanceTransform()和distanceTransformWithLabels()函数，它们的工作原理类似，但是与该Matlab函数有一些区别。从Matlab docs for bwdist:. D = bwdist(BW) computes the Euclidean distance transform of the binary image BW. For each pixel in BW, the distance transform assigns a number that is the distance between that pixel and the nearest nonzero …

02.04.2017 · 图像的距离变换实现了像素与图像区域的距离变换，使得最后生成的图像在该自己元素位置处的像素为0，临近的北京的像素具有较小的值，且随着距离的增大它的的数值也就越大。对于距离图像来说，图像中的每个像素的灰度值为该像素与距离其最近的背景像素间的距离，也就是说，给每个像素 ...

The function cv::distanceTransform calculates the approximate or precise distance from every binary image pixel to the nearest zero pixel. For zero image pixels, the distance will obviously be zero. When maskSize == DIST_MASK_PRECISE and distanceType == DIST_L2 , the function runs the algorithm described in [73] .

17.11.2021 · CV_EXPORTS_AS(distanceTransformWithLabels) void distanceTransform( InputArray src, OutputArray dst, OutputArray labels, int distanceType, int maskSize, int labelType = DIST_LABEL_CCOMP ); src：输入图像，数据类型为CV_8U的单通道图像

getTrackbarPos( 'threshold' , 'distrans' ). mark = cv2.Canny(img, thrs, 3 * thrs). dist, labels = cv2.distanceTransformWithLabels(~mark, cv.CV_DIST_L2, 5 ).

Oct 17, 2014 · Show activity on this post. I want to use the function distanceTransform () to find the minimum distance of non-zero pixels to zeros pixels, but also the position of that closest zero pixel. I call the second version of the function with the labelType flag set to DIST_LABEL_PIXEL. Everything works fine and I get the distances to and indices of ...
