The species component, density and index of crown cover in the tree layer effect on distributionofillumination and under plants in the plant community.
群落中光照的分布状况受乔木层的种类组成、密度与冠幅指数等因子的影响，且对下层植物分布有较大的作用。

The variations of object's reflection light induced from illumination variations and uneven illuminationdistribution greatly reduce the detecting efficiency in the process of color object detection.
彩色目标检测过程中由于环境光照的变化以及分布不均匀会造成物体反射光的改变，使得检测效率降低。

The basic idea is illuminating the scene with the light probe images. To simplify the design of local illumination model, the bidirectional transmit distribution function is introduced.
