Three important algorithms that use distance are: In this paper we present a new image completion algorithm powered by a huge database of photographs gathered from the web. 2 shows a flowchart for knn algorithm.

For selecting the most suitable number of neighbors (k), a sensitivity analysis for k is done which is shown in fig. The algorithm patches up holes in images by finding. Selecting the right number of clusters is important for meaningful segmentation to do this we use elbow method for optimal value of k in kmeans which is a graphical tool used.
Calculate the distance from each sample point to its nearest known cluster center.
