Image Mosaic Research Based on SIFT and Function Hard Correction Algorithm
Zhao Hong-son · Computer Knowledge and Technology · 2014
Image mosaic technology is widely used in many fields such as medical image analysis, computer recognition, remote sensing image processing, etc. In complex scenes, Considering the larger proportion of false matching points and more complex iteration when using SIFT algorithm to process image mosaic, the used RANSAC algorithm for purifying feature points accurately, and gets transition matrix. It proposed an improved hard correction method which used the fade in and fade out function to correct the gray value on both sides of seam-line, then removed the seam-line. Experiment shows that, the method is effective and easy to be realized.
