Color correction based image blending for creating high resolution panoramic images on mobile devices

摘要

We present a color correction based image blending approach which is capable of combining a set of aligned source images to a composite image and implement it in a mobile panorama system for creating high-resolution panoramic images on mobile devices. Our color correction is performed in the gamma-corrected RGB color space [2009a]. A global adjustment process is used for smoothing color transition in the whole image sequence and reducing cumulative errors. Unlike the work [2009a] which focuses on solving pixel saturation problems in using diagonal models [2002] in the RGB color space, here we are focusing on improving the blending quality and speed for long image sequences. We compare results and performance with a global blending approach [2009b] to demonstrate advantages of the color correction based image blending approach in creating high-resolution panoramic images on mobile devices.
