面子功夫——富士杭州试拍会侧记

云栖竹径，以竹韵，松声、溪光、云影为特色，四季皆含画意；春天破土而出的竹枝新芽一片嫩绿，频添央然生机；夏日，千株攒簇，万棵摇曳，送来丝丝凉意；秋天，黄叶绕地，夹径萧萧，撩起多少思绪：冬日，翠竹镶玉，飞鸟啄雪，林寂坞静，云栖竹径历史悠久，俞曲园的《春在堂随笔》中有这样的记述：“僧言从前弥望皆绿，仰不见天，今已濯濯，则云栖之竹遭樵夫斧斤，非近时始然也。”

A Multi-Condition Relighting with Optimal Feature Selection to Robust Face Recognition with Illumination Variation

In this paper, we proposed a new approach for face recognition with robust to illumination variation. The improved performance to various lights in recognition is obtained by a novel combination of multicondition relighting and optimal feature selection. Multi-condition relighting provides a "coarse" compensation for the variable illumination, and then the optimal feature selection further refines the compensation, and additionally offers the robustness to shadow and highlight, by deemphasizing the local mismatches caused by imprecise lighting compensation, shadow or highlight on recognition. For evaluation, two databases with various illumination mismatches have been used. The results have demonstrated the improved robustness of the new methods.
