Personal identification using images of the human palm
A prototype system for human identification using images of the palm is introduced. An image capture platform is constructed such that variation of the camera-to-palm distance is minimised to eliminate the need to compensate for scaling transformation. Appropriate lighting conditions are considered in order to enhance the palm features during image capture. The Hough transform is used to detect the palm features as approximated straight lines. Translation and rotation invariance are achieved by using the edge of the palm as a reference for all feature measurements.
