Abstract

Image mosaic is comprised of building a large field of view from a sequence of smaller images. It can be performed by registering, projective warping, resampling and compositing a serials of images. Due to the many possible factors for color and brightness variations when taking images, it is possible to lead to misalignment and obtain poor stitching result. Despite image mosaic can be manually adjusted using some photo editors like PhotoShop, this is not only tedious but also requires skills, knowledge and experience. Automatic adjustment is therefore desirable. By converting images to lαβ space and applying a special statistical analysis, color and brightness correction can be done automatically and improved image mosaic can be obtained.
