Automatic Image Mosacking

초록

This paper proposed the method of creating image mosaic in automated fashion. It is well known that geometric and radiometric balance in adjacent images should be main-tained in mosaicking process. The seam line to minimize geo-metric discontinuity was extracted using Minimum Absolute-Gray-Difference Sum considering constraint condition in search width. To maintain the radiometric balance of images acquired at different time, we utilized Match Cumulative Fre-quency, Match Mean and Standard Deviation and Hue Adjust-ment algorithm. The mosaicked image prepared by the pro-posed method was compared with those of commercial soft-ware. Experiments show that seam lines were extracted signifi-cantly well from roads, rivers, ridgelines etc. and Match Cumu-lative Frequency algorithm was performed pretty good in his-togram matching.
