Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms. Gestures can originate from any bodily motion or state but commonly originate from the face or hand. Current [ when? Users can use simple gestures to control or interact with devices without physically touching them. Many approaches have been made using cameras and computer vision algorithms to interpret sign language.

Real-time Hand Gesture Detection and Recognition for Human Computer Interaction Description Title: Real-time Hand Gesture Detection and Recognition for Human Computer Interaction Authors: Dardas, Nasser Hasan Abdel-Qader Date: Abstract: This thesis focuses on bare hand gesture recognition by proposing a new architecture to solve the problem of real-time vision-based hand detection, tracking, and gesture recognition for interaction with an application via hand gestures. The first stage of our system allows detecting and tracking a bare hand in a cluttered background using face subtraction, skin detection and contour comparison. The second stage allows recognizing hand gestures using bag-of-features and multi-class Support Vector Machine SVM algorithms. Finally, a grammar has been developed to generate gesture commands for application control. Our hand gesture recognition system consists of two steps: offline training and online testing. In the training stage, after extracting the keypoints for every training image using the Scale Invariance Feature Transform SIFT , a vector quantization technique will map keypoints from every training image into a unified dimensional histogram vector bag-of-words after K-means clustering. This histogram is treated as an input vector for a multi-class SVM to build the classifier.
