The minPoints parameter refers to k nearest neighbors around each point which make a circle and the point itself and these k points make primary cluster at very early stages of algorithm. (minPoints=k+1)
While, the minClusterSize, is used in last stages in order to merge clusters and build a denser hierarchy.
