Embodiment Construction

[0030] Taking the application program to be controlled as PPT (slideshow) as an example, the present invention will be further described in detail:

[0031] A gesture recognition control method based on hand contour features, such as figure 1 shown, including the following steps:

[0032] Step 1, the initial steps required to start the system, set the initial parameters of the system. For example, connect the camera to the computer, complete the parameters in the setting panel, and open the designated slideshow to show that the connection is successful, and then input the acquired video frames into the image processing step through the camera. During the specific implementation, you can use VC++ programming to design an MFC interface, design a start button for the camera and the slideshow, and check whether the connection is successful, and the design of the setting panel should include scene settings, fist settings, palm settings and file settings. Scene setting parameters ...

Abstract

The invention discloses a method and system used for recognizing and controlling a gesture and based on a hand profile feature. The method is mainly formed by an initial setting step, an image pre-processing step, a gesture recognizing step, a command parsing step and a controlling step for an application program to be controlled. Gesture recognition is conducted by extracting an outer profile of a video frame, the gesture is recognized according to gesture feature area and gesture feature perimeter in a gesture recognition process, a fist and a palm are described by using the sum of convex hull flaw area, and accuracy and efficiency of palm recognition are effectively improved. In the gesture recognition process, only common computational discrimination such as perimeter and area are used instead of a complex image mode recognition sample comparison method, so that an extra sample base is not required to be added and can develop service for other applications such as a picture viewer, a music player, a webpage browner and a game application program which are based on gesture control.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a gesture recognition control method and system based on hand contour features. Background technique [0002] The human-computer interaction method of using gestures to control the computer is gradually becoming the development direction and trend of human-computer interaction. At present, people often need hardware devices such as auxiliary keyboard, mouse and control pen to control the internal application software of the computer (such as video playback software and PPT slideshow software), which cannot free the hands of users. For example, people often use slideshow software such as PPT to assist in displaying content, and the way the speaker controls the slideshow mainly depends on hardware devices such as keyboard, mouse, and control pen, which cannot free hands for the speaker to interact with the audience. [0003] The current gesture interaction system adopts t...
