Feature Description and Spatio‐temporal Analysis of Bio‐Medical Images

Abstract

This paper addresses some feature description and satio‐temporal analysis methods for bio‐medical images. Recently various kinds of diagnostic imaging systems have been developed. However, it is still important to improve the efficiency and performance of image processing techniques in biological and medical fields. Especially, texture and motion analyses of spatio‐temporal images like 3 dimensional time lapse data of ultra‐sound images, CT images and cell division images will give a new aspect for computer‐aided diagnosis. Because we will be able to obtain some information about 3D micro‐structure of cells or organs. In this paper, two optical flow methods for motion analysis and two texture feature descriptors are reviewed, and some examples of these processings are given.
