摘要
当照度不均匀时,图像上对应照度暗的部分,其细节就较难分辨,利用基于光照反射模型的同态滤波可以消除不足照度的影响而又不损失图像的细节.
When the illumination is not fair, some part of the image with low illumination is not clear. The homomorphie filtering approach is derived from an illumination-reflectance model of the image. Homomorphie filtering can perform simultaneous dynamic range compression and contrast enhancement.
