Image Segmentation Techniques: An Overview
نویسندگان
چکیده
Image segmentation means extracting the part of an image or any object.In digital image processing, image segmentation plays a vital role in the processing of images.Image segmentation is one of the most important steps leading to the analysis of processed image data. The goal of image segmentation is pattern recognition and image analysis besides simplifying the representation of an image which is more meaningful. It is used in various applications like medical imaging, machine vision, traffic control systems, image recognition tasks etc.In this paper, review of various image segmentation techniques and comparison between different techniques is done.

An Improved Pixon-Based Approach for Image Segmentation
An improved pixon-based method is proposed in this paper for image segmentation. In thisapproach, a wavelet thresholding technique is initially applied on the image to reduce noise and toslightly smooth the image. This technique causes an image not to be oversegmented when the pixonbasedmethod is used. Indeed, the wavelet thresholding, as a pre-processing step, eliminates theunnecessary details...
متن کاملSegmentation Assisted Object Distinction for Direct Volume Rendering
Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...

متن کاملAn Overview of Interactive Medical Image Segmentation
Image segmentation is often described as partitioning an image into a finite number of semantically non-overlapping regions. In medical applications, it is a fundamental process in most systems that support medical diagnosis, surgical planning and treatments. Generally, this process is done manually by clinicians, which may be time-consuming and tedious. To alleviate the problem, a number of in...
