Images are segmented by marking pixel as object pixels or back-ground pixel this helps us in highlighting the area that is to be used for analysis more clearly. There are various techniques by which this can be achieved for both grayscale images and coloured images. The accuracy and efficiency of the segmentation depends on the precision by which all the variables are incorporated. A lot of research has been done in developing such methods of segmentation or partitioning of images. In present paper a survey of various methods of Image segmentation models has been discussed.

In this paper, the collective information about all the available cardiac image datasets are described. Hence all the approaches which are used for the Cardiac Image segmentation are reviewed. The Review on these techniques shows that the modern deep learning techniques which are used with high speed GPU’s will deliver best result when compared with the other traditional image segmentation techniques.

In this paper, we proposed a new image segmentation scheme based on the multiresolution image by a wavelet transform and the image segmentation by a watershed transform. At first, the original image is transform into a multiresolution image by using Haar wavelets. Then, the watershed of the lowest-resolution image is computed. To avoid over-segmentation, a fuzzy similarity criteria is introduced to merge neighboring regions. Experimental results demonstrate that the presented scheme can be applied to the segmentation of noise or degraded images as well as to over-segmentation.

Recursive tree-structured segmentation is a powerful tool to deal with the non-stationary nature of images. By fitting model parameters to each region/class under analysis one can adapt the segmentation algorithm to the local image statistics, thus improving accuracy. However, a single model/segmenter cannot fit regions with wildly different nature, and one should be allowed to select in a suitable library the tool most suited to the local statistics. In this paper, we implement this dynamic segmentation/classification paradigm, using two segmenters, based on spectral and textural properties, respectively, and defining suitable rules for switching model locally. Experiments on remote-sensing mosaics show that the multiple-model dynamic algorithm largely outperforms comparable single-model segmenters.
