Web22 de abr. de 2024 · Here is one way to do that in Python/OpenCV/Skimage. The idea is to use some Gaussian blur. Then use kmeans processing to get 3 colors. Then threshold to get the middle color and clean it up with some morphology close and open. Then get the contour and draw it on the input. Input: Webanchor_in – Position of the anchor within the element. borderType_in – Border mode used to extrapolate pixels outside of the image, see cv::BorderTypes. image_in – Source image. The number of channels can be arbitrary. The depth should be one of CV_8U, CV_16U, CV_16S, CV_32F` or `` CV_64F. iterations_in – Number of times erosion is applied. お風呂 床 泥汚れ https://thewhibleys.com
