Biometria de veias: um método para extrair as informações discriminantes da imagem do dorso da mão

This article describes a method for segmenting images of the dorsal hand for the purpose of locating and extracting the pixels that compose the veins region in the images. Thus, it is possible to identify a person using veins information as a biometric feature. The article also describes the steps of a complete biometric system. At the end, we present the results of experimental tests of the proposed techniques using a vein image data base.
