Sequential Images Mosaic Based on Interest-point Detection and Affine Transform Model
Weidong Yan · Laser & Infrared · 2009
For the problem of the sequential image mosaic,a new method for image registration based on the interest-point detection and affine transform model is proposed firstly,which detects interest-points by the Harris operator,and introduces a two-level restricted tactic based on cross match and coordinate scattering to gain the homonymy points.Then image registration is carried out according to the affine transform model.A normalized adaptive weighted function is given for eliminating the mosaic-sew caused by the difference of the pixel gray in the images,which makes the smoothly transition of the mosaic image.The experiment results indicate that approach proposed has good registration precision and nice effect of pixel-fusion.
