There are multiple crimes happening even in the presence of cctv cameras still we couldn’t able to find the identity due to shadows in the image. In this work, we have used edge suppression method and affine transformation to recognize identity even under severe shadow. We also used gradient field to calculate the position of light sources in the place. For classification of identity from the databases we use k-nearest neighbor rule. Additionally we also were using this principal component analysis for feature extraction. Classification can be done in real time environments by accessing authorized databases or also by standard databases.
