Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] figure 1 Schematically represents the principle of the self-learning hand tracking device based on the skin color model.

[0049] Such as figure 1 As shown, the self-learning hand tracking device based on the skin color model includes: a pre-processing unit 1 , a self-learning unit 2 , and a post-processing unit 3 . The preprocessing unit 1 extracts the hand candidate area from the current frame image, and obtains the initial hand area h from the hand candidate area through morphological detection init and the input object of the hand recognizer ∑(h 1 ,h 2 … h m ), the self-learning unit 2 uses the hand candidate area and the initial hand area h init Self-learning, get the hand area h after self-learning in this frame final, post-order processing unit 3 for the hand area h after self-learning in this frame final Processing, get the hand c...

Abstract

Provided are a device and a method self-learning skin-color model based hand portion tracking. The device of self-learning skin-color model based hand portion tracking comprises a preprocessing unit which is used for extracting a hand candidate area from an image in a frame and obtaining an initial hand area HINIT through a morphologic detection, a self-learning unit which is used for self-learning using the hand waiting area and the initial hand area HINIT to obtain a hand area HFINAL after self-learning of the frame, and a subsequent processing unit which is used for processing the hand area HFINAL after original frame self-learning to obtain a hand outline and finger tip positions. The self-learning unit comprises a hand tracker, a hand recognizer and a P-N learning device. The self-learning skin-color model based hand portion tracking method includes a preprocessing step, self-learning and P-N classifying steps and a subsequent processing step. The self-learning and P-N sorting step includes a hand tracking step, a hand recognizing step and a P-N learning and sorting classifying step. According to the device and the method of self-learning skin-color model based hand portion tracking, robustness is good and hand tracking is stable and accurate when a hand passes through heavy interference areas such as a face or when a hand is sheltered.

Description

technical field [0001] The invention relates to gesture recognition and hand tracking in the field of human-computer interaction, in particular to a self-learning hand tracking device and method based on a skin color model. Background technique [0002] With the development of computer technology, human-computer interaction technology is also undergoing tremendous changes. People hope to communicate and interact with computers more and more conveniently. At present, in the field of human-computer interaction technology, the relative maturity of multimedia technology has greatly improved the ability of computer information presentation, but it also shows a serious shortage of interactive input means, showing a serious disconnect between human and computer input and output communication bandwidth. The research on multi-channel human-computer interaction technology breaks the routine, breaks through the limitations of traditional interactive devices, such as mouse, keyboard, re...
