WebWorking of Mean-Shift Algorithm. We can understand the working of Mean-Shift clustering algorithm with the help of following steps −. Step 1 − First, start with the data points assigned to a cluster of their own. Step 2 − Next, this algorithm will compute the centroids. Step 3 − In this step, location of new centroids will be updated. WebMar 11, 2013 · This source, which was found on the EDISON site, claims to be a c++ implementation of the mean shift clustering algorithm, but as discussed above, clustering is the main implementation of the mode seeking behavior that all other uses of mean shift is based on, especially segmentation, so you can certainly use the EDISON source to find a …
