Real Time Person Independent Communication Between Dumb and Blind Person Using Sign and Text Detection

Robust Person-Independent Visual Sign Language Recognition

Sign language recognition constitutes a challenging field of research in computer vision. Common problems like overlap, ambiguities, and minimal pairs occur frequently and require robust algorithms for feature extraction and processing. We present a system that performs person-dependent recognition of 232 isolated signs with an accuracy of 99.3% in a controlled environment. Person-independent r...

Person-Independent 3D Sign Language Recognition

We present an automatic sign language recognition system that is vision-based, person-independent, and non-obtrusive. Its task is to evaluate the correctness of an isolated sign. The unique features are an adaptive skin model to find the hands, 3D features, Dynamic Time Warping for synchronising signs and automatic feature selection for finding the best sign representation. A Dutch 120-sign voc...

Person Independent Facial Expression Detection using MBWM and Multiclass SVM

Facial expression analysis is an attractive, challenging and important field of study in facial analysis. It's important applications include many areas such as human–computer interaction, human emotion analysis, biometric authentication, exhaustion detection and data-driven animation. For successful facial expression recognition, the first step is to arrive at an appropriate facial repres...

Real-Time Multi-Person Tracking with Time-Constrained Detection

This paper presents a robust real-time multi-person tracking framework for busy street scenes. Tracking-by-detection approaches have recently been successfully applied to this task. However, their run-time is still limited by the computationally expensive object detection component. In this paper, we therefore consider the problem of making best use of an object detector with a fixed and very s...
