OpenCV: Image Segmentation with Watershed Algorithm We will see: cv.watershed() Theory . Any grayscale image can be viewed as a topographic surface where high intensity denotes peaks and hills while low intensity denotes valleys. You start filling every isolated valleys (local minima) with different colored water (labels). As the water rises, depending on the peaks (gradients) nearby, water from ... OpenCV: Image Segmentation with Distance Transform and Watershed Algorithm Prev Tutorial: Point Polygon Test Next Tutorial: Out of focus Deblur Filter Goal . In this tutorial you will learn how to: 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 ... Watershed OpenCV PyImageSearch The watershed algorithm is a classic algorithm used for segmentation and is especially useful when extracting touching or overlapping objects in images, such as the coins in the figure above.. Using traditional image processing methods such as thresholding and contour detection, we would be unable to extract each individual coin from the image — but by leveraging the watershed algorithm, we ...
