In digital image processing and computer vision, image segmentation is the process of partitioning a digital image into multiple segments (sets of pixels, also known as image objects). With the consideration of the characteristics of each object composing images in MPEG4, object-based segmentation cannot be ignored. Abstract-Image segmentation is one of the essential problems in computer vision and image processing. –probabilistic methods. Introduction Segmentation refers to another step in image processing methods where input are images and outputs are attributes extracted from images. Image segmentation partitions the image into segments based on their certain features such as color, texture, intensity values etc. 1. –… Goal: separate an image into “coherent” regions. Image segmentation is a commonly used technique in digital image processing and analysis to partition an image into multiple parts or regions, often based on the characteristics of the pixels in the image. B.Brain Tumor Segmentation and medical image processing, and computer vision [17]. Digital Image Processing Segmentation DR . Image processing is the form of signal processing where both the input and output signals are images.
