Abstract
Image segmentation, a major research class is frequently governed by the way of two foremost parameters, associated with a specified segmentation procedure: threshold decision and seed-point determination. Various methods such as the histogram based processes, entropy headquartered process, business measure approaches and so on. These are well recognized for threshold choice within the image segmentation issues. In this article, threshold determination is done on the basis of extraordinary entropy measures on each of grey scale and color images. Comparative analysis of the Shannon and non-Shannon entropies (Renyi, Havrda-Charvat, Kapur and Vajda) is done to receive an appropriate threshold worth for the perfect image segmentation. It’s concluded via the simulation experiments performed on MRI images, that the role of the smallest minima obtained within the entropy versus grey-degree plot is different for every entropy measure. The threshold values received from these plots is accordingly elegant on the specific definition of the entropy chosen, which in flip influences segmentation outcome. It’s further observed that the segmentation results acquired, making use of Havrda-Charvat entropy measure is healthier than other entropy measures.
