Segmentation is the process of partitioning an image into a number of significant images such as segments or clusters. Segmentation is an initial but important process that is used to locate borders and objects in images. Image segmentation is required for object detection. Particularly for images where the intensity of the object and background is not distinguishable then the process of segmentation becomes difficult. Therefore, there is a need to develop algorithms to obtain a solid segmentation of images for the detection of targets. In general, image segmentation depends on criteria dependent on the threshold. And optimal threshold selection is difficult and complex for multimodal imaging. That is, there is a possibility that the region can not be properly segmented. It has been seen that the neural network is a good approach to analyze images and segment different objects present in a given image.
