Problems solved by technology

According to the skin color information, the gesture area in the scene image is segmented to obtain the gesture image, and then the geometric features of the gesture are easily affected by deformation. Considering the geometric features of the gesture from many aspects, a layered gesture recognition algorithm is studied to avoid feature data. Fusion brings complex computing problems, using gesture geometric features to model and classify gestures, improving gesture recognition rate

Embodiment Construction

[0028] The preferred technical method of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] A static gesture recognition method based on the bounding box model, such as figure 1 As shown in the flow, first, the scene image is detected by hand region to obtain the gesture image. The process of recognizing gesture images is divided into two layers. Layer 1 uses morphological operations to detect fingers, and preliminarily classifies gestures according to the index of fingers to realize initial recognition of gestures. The obtained result can be output as the final recognition result. Layer 2 is based on the recognition of layer 1, for gesture type 2 that needs to be further identified, combined with the relative fixed position between the fingers, extract the finger spacing and the angle between the fingers, model the gesture and classify it again, and finally Implement gesture recognition. Specific steps are as foll...

Abstract

The invention relates to a static gesture recognition method based on a bounding box. The method comprises the following steps: segmenting a gesture region in a scene image according to skin color information, and obtaining a gesture image; secondly, considering the geometrical characteristics of the gestures from multiple aspects aiming at the influence of deformation on the geometrical characteristics of the gestures, proposing an idea of utilizing a layering strategy, and realizing recognition tasks of various gestures in two steps; firstly, the number of fingers in a gesture image is detected; on the basis, gesture modeling is carried out by utilizing the relative positions of fingers, multi-type gesture classification is converted into classification of two gesture types in the current step, the problem of complex calculation caused by feature data fusion is avoided, gesture modeling and classification are carried out by utilizing gesture geometrical features, and the gesture recognition rate is improved.

Description

technical field [0001] The invention relates to computer vision, in particular to a static gesture recognition method based on a bounding box model. Background technique [0002] With the development of science and technology, human-computer interaction technology has gradually become the focus of computer research. As a humanized interaction method - gesture, it has more natural, simpler and stronger real-time characteristics. Gesture recognition algorithms have been widely used in various fields, and the popularity of gesture recognition has made human-computer interaction easier. Gesture is usually defined as a specific semantic system formed by the position and shape of the palm and fingers to express a specific meaning. Gestures can be divided into static gestures and dynamic gestures. Static gestures represent the spatial gesture of the hand at a certain moment, while dynamic gestures emphasize the sequence of hand gestures in a period of time. [0003] Geometric fe...
