The workflow of the connected components module is: Create connected components handle. dwImagePropertiesinputProps{}; inputProps.width= width; inputProps.height = height; inputProps.type =DW_IMAGE_CUDA; inputProps.format =DW_IMAGE_FORMAT_R_UINT8; ...
the input should be a pitch linear CUDA image the format of an input image should be one of DW_IMAGE_FORMAT_R_UINT8, DW_IMAGE_FORMAT_YUV420_UINT8_PLANAR or DW_IMAGE_FORMAT_YUV_UINT8_PLANAR Relevant Tutorials Connected Components Workflow APIs Connected Components Interface Advance...
OpenCV中的新函数connectedComponentsWithStats使用 主要内容:对比新旧函数,用于过滤原始图像中轮廓分析后较小的区域,留下较大区域。 关键字:connectedComponentsWithStats 是先调用 cv::findContours() 函数(传入 cv::RETR_CCOMP 标志),随后在得到的连通区域上循环调用 cv::drawContours() “...

It is clear that for an N × N-sized image, the maximum number of connected components in a binary image is N × N/4, i.e., the maximum number of provisional labels to be assigned is N × N/4. Three methods have been proposed for equivalent label recording and label-...
