PANORAMIC IMAGE STITCHING USING A PROBABILISTIC COLOUR CORRECTION APPROACH
Journal Title: Elysium Journal of Engineering Research and Management - Year 2016, Vol 3, Issue 3
Abstract
Image mosaicing in image processing is a technique in which two or more partially overlapping images of the same scene taken at different times and from different positions are combined together to get a more clearer view of the scene. Image mosaics are obtained by performing geometrical and photometrical corrections to the images. This paper deals with colour correction of panoramic images. Mean shift algorithm is employed to segment the image into several regions. Region fusion algorithm thereafter extracts the connected regions. Maximum likelihood estimation procedure models the local joint image histograms as truncated Gaussians. These sets of Gaussians are then used to compute the local colour palette mapping functions. These mapping functions are then applied to the image to establish colour correction.
