In any case, normally, VHR pictures are influenced by the vicinity of shadows. An endeavour answer for the issue of shadows is to restore shadow areas by reparing the estimation of shaded pixels. Unfortunately, it might happen that not all shadow zones are conceivable to restore. In this paper, we propose distinctive criteria valuable to help in comprehension from the earlier in the event that it is conceivable or not to remake a specific shadow region. A perfect reconstructability rule ought not endure that an unreconstructable shadow territory is allotted as reconstructable and, in the meantime, ought to augment the likelihood of discovery of reconstructable zones. A few assessment criteria working at the pixel and textural levels are introduced.

In this paper we have proposed a method for obtaining reconstructability of shadow areas in VHR images. In the proposed method first shadow areas are detected through shadow mask. Shadow and non-shadow area are separated. Histogram of shadow and non-shadow area are applied to eight criteria working at the texture and pixel level. Values obtained by means of criteria are compared with reference values. It will provide objective assessment of reconstructability of shadow area. If shadow area is reconstructable then it is reconstructed by using additive and ycbcr reconstruction technique.
