This paper presents a contactless hand biometric system at unrestricted hand pose environment. A new preprocessing technique is proposed for defining the finger contour profiles (FCP). It mainly consists of simple grayscale image transformation, subtraction, and logical XOR operation. This hand prototyping method logically decomposes global hand contour into the left and right contour profiles of...
Over the last forty years several different techniques have been proposed for human face recognition. This has been used in different application especially in the field, where security is the main concern. Most of the face recognition algorithms work on visual face images. But the visual face images have several drawbacks because the quality of the visual images degrades gradually with the increase...
This paper describes an efficient approach for human face recognition based on blood perfusion data from infra-red face images. Blood perfusion data are characterized by the regional blood flow in human tissue and therefore do not depend entirely on surrounding temperature. These data bear a great potential for deriving discriminating facial thermogram for better classification and recognition of...
