چکیده

We present a method to recognize hand gestures, based on a pattern recognition technique developed by McConnell [16] employing histograms of local orientation. We use the orientation histogram as a feature vector for gesture class cation and interpolation. This method is simple and fast to compute, and o ers some robustness to scene illumination changes. We have implemented a real-time version, which can distinguish a small vocabulary of about 10 di erent hand gestures. All the computation occurs on a workstation; special hardware is used only to digitize the image. A user can operate a computer graphic crane under hand gesture control, or play a game. We discuss limitations of this method. For moving or \dynamic gestures", the histogram of the spatio-temporal gradients of image intensity form the analogous feature vector and may be useful for dynamic gesture recognition.

Computer vision for computer games

The appeal of computer games may be enhanced by vision-based user inputs. The high speed and low cost requirements for near-term, mass-market game applications make system design challenging. The response time of the vision interface should be less than a video frame time and the interface should cost less than 50 Dollars U.S. We meet these constraints with algorithms tailored to particular har...

Recognition of Isolated fingerspelling Gesturs Using Depth Edges

Although steady progress has been made on developing vision-based gesture recognition systems, state-of-the-art approaches are still limited to discriminate hand configurations with high amounts of finger occlusions, a common scenario in most fingerspelling alphabets. In this article, we propose a novel method for recognition of isolated fingerspelling gestures based on depth edge features. Our...

Computer Vision for Interactive Computer Graphics

Computers looking through a camera at people is a potentially powerful technique to facilitate human-computer interaction. The computer can interpret the userś movements, gestures, and glances. Fundamental visual algorithms include tracking, shape recognition, and motion analysis. We describe several vision algorithms for interactive graphics, and present various vision controlled graphics appl...

Face Recognition Using Boosted Local Features

This paper presents a new method for face recognition which learns a face similarity measure from example image pairs. A set of computationally efficient “rectangle” features are described which act on pairs of input images. The features compare regions within the input images at different locations, scales, and orientations. The AdaBoost algorithm is used to train the face similarity function ...
