Shadow Eliminating Using Edge-Fuzzied-Retinex in Urban Colored Aerial Image
Xiao Zhi-ji · Chinese Journal of Stereology and Image Analysis · 2004
The limitation of the SSR algorithm is analyzed when applying to shadow eliminating, and a new approach eliminating shadows in colored aerial image,called Edge-Fuzzied-Retinex, is proposed. The color image is first segment into shadow region and non-shadow region using a shadow detection algorithm with the region border fuzzied,then the SSR algorithm is appied to the two regions, respectively,finally the two are comined together.The results demonstrate that such approach workes well.
