چکیده

In this paper, we present a self-organizing framework called the SHOSLIF-M for learning and recognizing spa-tiotemporal events (or patterns) from intensity image sequences. The proposed framework consists of a mul-ticlass, multivariate discriminant analysis to automatically select the most discriminating features (MDF), a space partition tree to achieve a logarithmic retrieval time complexity for a database of n items, and a general interpolation scheme to do view inference and generalization in the MDF space based on a small number of training samples. The system is tested to recognize 28 diierent hand signs. The experimental results show that the learned system can achieve a 96% recognition rate for test sequences that have not been used in the training phase.

Shoslif-m: Shoslif for Motion Understanding (phase I for Hand Sign Recognition)

In this paper, we propose a new general framework for learning and recognizing spatiotemporal events (or patterns) from intensity image sequences. This scheme is general in that it does not impose any motion model on the input. A multiclass, multivariate discriminant analysis technique has been used to automatically select the most discriminating features (MDF) which is shown to be better suite...

SHOSLIF: A Framework for Sensor-Based Learning for High-Dimensional Complex Systems

1 Learning directly from various sensors, visual, auditory , tactile, etc., plays a central role in the development of human's intelligence. In contrast to approaches of hand-crafting knowledge-level rules or models for complex intelligent systems, the SHOSLIF approach uses a comprehensive learning approach, which characterizes signal-level representation, learning and system self-organization ...

Shoslif-o: Shoslif for Object Recognition and Image Retrieval (phase Ii)

We describe a self-organizing framework for content-based retrieval of images from large image databases. The SHOSLIF (Self-organizing Hierarchical Optimal Subspace Learning and Inference Framework) system uses the theories of optimal linear projection for automatic optimal feature selection and a hierarchical image database organization to achieve a logarithmic retrieval complexity. We use inc...

Applying mean shift and motion detection approaches to hand tracking in sign language

Hand gesture recognition is very important to communicate in sign language. In this paper, an effective object tracking and hand gesture recognition method is proposed. This method is combination of two well-known approaches, the mean shift and the motion detection algorithm. The mean shift algorithm can track objects based on the color, then when hand passes the face occlusion happens. Several...
