Abstract

When digital images are mosaicked, brightness difference between to-be-mosaicked images will result in mosaic artifacts in the final mosaicked image due to non-uniformity caused by optical system vignetting as well as gain changes automatically caused by scene changes. An brightness adaptive algorithm for image mosaic seamless fusion has been studied in this paper. The process of the method are as follows; 1) estimating the visibility of stitching traces according to brightness differences between to-be-mosaicked images; 2) adjusting the brightness of the images to be mosaicked in order to reduce the brightness difference until the mosaic aitifacts can not be perceived by human visual system; 3)blending the images to be mosaicked based on mul-tiscale analysis method. The experiment indicates that the method is adaptive to adjust brightness for seamless blending based on multi-scale analysis, and the mosaiced image quality can meet the requirements of human vision.
