发明名称 METHOD AND SYSTEM FOR ESTIMATING MOTION
摘要 <P>PROBLEM TO BE SOLVED: To provide a method and a system capable of estimating motion of consecutive images. <P>SOLUTION: The method includes; (a) a step for obtaining each first and second sub-images at n level by filtering and decomposing the consecutive first and second images based on frequency components of images at a predetermined number of times, (b) a step for selecting a feature pixel from among each pixel of the first sub-image, (c) a step for selecting an image block of the feature pixel and the circumjacent pixel from the first sub-image, (d) a step for comparing the second sub-image with the image block and selecting a reference region from the second sub-image, (e) a step for calculating a displacement parameter between the image block and the reference area, (f) a step for storing the calculated displacement parameter, (g) a step for synthesizing the first and second sub-images in case that the first and second sub-images are each at a higher level than the image at the first level, (h) a step for applying these steps (b)-(e) to the composed first and second sub-images, and (i) a step for estimating motion from the stored displacement parameter. <P>COPYRIGHT: (C)2007,JPO&INPIT
