الملخص الإنجليزي

Hand gesture recognition offers untraditional medium for HC1 (Human-Computer Interaction) tilt can be both efficient and highly intuitive ; However, gesture recognition software is still in its infancy.

While many researchers have documented methods for recognizing complex gestures from Instrumented gloves at high levels of accuracy, these systems suffer from two notable imitations : device dependence and lack of extension hi laity, A vision based static hand gesture recognition algorithm is proposed for Human-Computer Interaction based on neural network classifier.

The goal of static hand gesture recognition is to classify the given hand gesture data, represented by some features, into some predefined finite number of gesture classes.

In this thesis two methods have been presented for recognition of six specific static hand gestures namely : (Open, Close 7 Cut.

Paste, Maximize and Minimize), these gestures define a vocabulary of commands used to interact with the computer.

The hand gesture image is passed in three stages : preprocessing, feature extraction, and classification.

In preprocessing Stage some operations are applied to extract the hand gesture from its background and prepare the hand gesture image for the feature extraction stage.

In the first method the hand contour is used as a feature that treats scaling and translation problems (in some cases) - On the other hand the complex moments are used to describe the hand gesture in the second method and treat the rotation problem in addition to the scaling and translation.

The Last stage of the proposed algorithm is the malt! - Layer neural network classifier thatus.es back-propagation Learning algorithm.

The results showed that the first method has a performance of fTG.S3 <> i recognition rate^ and the second method has- a better performance of £86.3 H % recognition rate.

The proposed algorithm is imp lamented in Visual Basic Programming, Language ver.
