Introduction to OpenCV watershed. There are several algorithms for the purpose of segmentation and one such algorithm is the watershed algorithm using which the touching or overlapping objects in a given image can be extracted and for the functioning of the algorithm, user-defined markers are necessary which can be defined manually by point and click or user-defined methods can be defined ...

One of the most popular methods for image segmentation is called the Watershed algorithm. It is often used when we are dealing with one of the ...

06.05.2021 · Syntax to define watershed () function in OpenCV: watershed (-Euclideandistance, markers, mask) Where, Euclideandistance is the Euclidean distance to the closest zero for each of the foreground pixels in the given image …

Jan 08, 2013 · So OpenCV implemented a marker-based watershed algorithm where you specify which are all valley points are to be merged and which are not. It is an interactive image segmentation. What we do is to give different labels for our object we know. Label the region which we are sure of being the foreground or object with one color (or intensity ...

OpenCV. OpenCV provides a built-in cv2.watershed () function that performs a marker-based image segmentation using the watershed algorithm. This takes as input the image (8-bit, 3-channel) along with the markers (32-bit, single-channel) and outputs the modified marker array. The syntax is given below.

So OpenCV implemented a marker-based watershed algorithm where you specify which are all valley points are to be merged and which are not.
