METHOD AND APPARATUS FOR IMAGE GENERATION

Method and apparatus for image generation from biometric data is disclosed herein. In a described embodiment, the biometric data is in the form of IrisCode and the method comprises constructing a graph of filter responses and bits which define the biometric data; comparing the bits with corresponding bits of reference graphs of a trained database to obtain an optimal graph; updating the filter responses based on the optimal graph; and decompressing the IrisCode based on the updated filter responses to generate an image. The image may be a reconstruction of an original image which is defined by the IrisCode.
