Application of Gray Projection Algorithm to Acquiring Displacement Vectors of a Dynamic Image
Hongbo Zhao · Guangdian gongcheng · 2001
Acquisition of image motion information by use of gray projection algorithm has the advantages of high calculation speed and high accuracy. But in the past this algorithm was only applied to processing ideal dynamic image, i.e., the image only with some translation. This case limits the further application of the algorithm. Through analyzing several dynamic images with more complicated motion characteristics and after the corresponding preprocessing methods have been adopted, this algorithm can accurately process images, thus the applicable range of gray projection algorithm can be extended.
