Review on Image Segmentation Using Mapping Method

In this paper, we are going to discuss various concepts related to image segmentation and different mapping methods. We have discussed Poincare maps for segmentation of images. To implement this method, we have to consider pair wise region comparison so that we get to know the minimum edge weight comprising between two regions and also calculate difference between both of them. We have discussed other mapping methods also which have their own importance to show grids of local surrounding points between pixels. These methods can also represent mapping of pixels in feature space. It has been shown that modes of segmentation can be very coarse or fine. They can be defined through some function that measures the boundaries which displays the difference between pair of regions. The executed region based mapping results in greedy decisions but the global property of the region is also carefully taken into consideration.
