Real time Hand Gesture Recognition using different algorithms based on American Sign Language

Human Computer Interaction (HCI) is a broad research field based on human interaction with computers or machines. Basically, Hand Gesture Recognition (HGR) is a subfield of HCI. Today, many researchers are working on different HGR applications like game controlling, robot control, smart home system, medical services etc. The purpose of this paper is to represent a real time HGR system based on American Sign Language (ASL) recognition with greater accuracy. This system acquires gesture images of ASL with black background from mobile video camera for feature extraction. In the processing phase, the system extracts five features such as fingertip finder, eccentricity, elongatedness, pixel segmentation and rotation. For feature extraction, a new algorithm is proposed which basically combines K curvature and…
