Digital image mosaics from video sequence can be defined as image registration and blending of multiple video frames into a single wide field of view image or dynamic panoramic image.The techniques of digital image mosaics from video sequence consist of image global fast registration algorithm,motion object segment algorithm,and seamless blending algorithm.The goals of this paper are as follows:a) analyze the properties of an ideal digital image mosaics system;b) introduce the evolvement of research on techniques of digital image mosaics from video sequence in recent years;c) provide its new direction for future research.
