Human hand image analysis extracting finger coordinates and axial vectors: Finger axis detection using blob extraction and line fitting
Pavel Jetenský · 2014
This paper presents a finger cut-off algorithm for accurate calculation of fingertip coordinates based on hand contours. It provides not only information on exact fingertip position but also orientation and lengths of all fingers in the image. Algorithm can be used for development of user interfaces based on human gesture analysis, such as TouchTable, multimodal gesture based user interface developed by the author. Advantages of proposed algorithm over fingertip detection algorithm originally used in TouchTable are described.
