Leaf area index (LAI) is a critical biophysical variable that describes canopy geometric structures and growth conditions. The scaling effect of LAI has always been of concern. Considering the effects of the clumping indices on the BRDF models in discrete canopies, an effective LAI is defined. The effective LAI has the same function of describing the leaves(More)
Multi-scale Retinex algorithm is an image enhancement algorithm that aims at image reconstruction. The algorithm maintains the high fidelity and the dynamic range compression of the image, so the enhancement effect is obvious. The algorithm exploits a large number of convolution operations to achieve dynamic range compression and color/brightness rendition,(More)
