Embodiment Construction

[0024] The present invention will be described in detail below, and it should be noted that the described embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.

[0025] Such as figure 1 As shown, the flow chart of the real-time gesture interaction method integrating hand detection, tracking and gesture recognition of the present invention is shown, which provides a possible way of applying the hand detection, tracking and gesture recognition technology described in the present invention for human-computer interaction. It should be noted that the hand detection and hand tracking methods described in the present invention can be used alone as a human-computer interaction method and applied to game control, home appliance control, and the like.

[0026] The hardware required for realizing the method of the present invention is a computer and image acquisition equipment.

[0027] The human hand detection refers to autom...

Abstract

The invention discloses a real-time gesture interaction method based on computer vision, which comprises the following steps: acquiring a digital image from an image input device; detecting hands by a statistical learning method; initializing a hand contour tracker according to the detecting result, and calculating a skin color model of a specific hand; tracking the hand contour by a combined method of a conditional probability density transmission algorithm and a heuristic search technology; analyzing the moving track of the hands by a Hidden Markov Model to obtain the gesture identifying result; and applying the gesture analyzing result to the interaction of various application programs. The real-time gesture interaction method of the invention expands the interactive mode of the traditional mouse and keyboard, realizes automatic hand detection, tracking and gesture identification by the computer vision and image processing techniques, has real-time performance, robustness and easy realization and operation, and can enable computer users to interact with the computer more naturally, visually and intelligently by hand gestures.

Description

technical field [0001] The invention relates to the technical field of image analysis and recognition, in particular to an interaction method based on gestures. Background technique [0002] In recent years, with the rapid development of software and hardware technology, the degree of social informatization has been improved unprecedentedly, and computers have gradually been widely used in all aspects of people's lives. Therefore, the way of human-computer interaction has become an increasingly important issue. From the initial text interaction method to the graphical user interface with mouse and keyboard as the main tool, human-computer interaction has been developing in a friendly and easy-to-use direction. [0003] Although the traditional interaction method has many advantages, it is still not natural enough and limits the speed of human-computer interaction, especially for low-education groups and disabled groups. Gesture interaction technology based on computer visio...
