Abstract

The invention discloses a dynamic gesture identification method in an interactive system, comprising the following four steps of: acquiring an image, and obtaining a current image frame after denoising; obtaining a moving region of the image by calculating the difference of the current image frame and a reference image frame, and obtaining a binary image by a skin color detection method; carrying out gesture segmentation on the binary image by a gray level projection method to obtain a gesture region and a barycentric position; and obtaining a final identification result by a classification identification method according to the barycentric position and fingertip characteristics. The method can be used for overcoming the problems of high complexity, low real-time quality and low identification rate in traditional algorithms, has the advantages of simplicity in implementation, good real-time quality and high identification rate, and can be applied to the dynamic gesture identification very well. Moreover, the method can tolerate the translation of a definition gesture, the scale and the transformation of a rotation angle, and has a good robustness.

Description

technical field [0001] The invention relates to the technical field of image analysis and recognition, in particular to a dynamic gesture recognition method in an interactive system. Background technique [0002] As we all know, the traditional mouse is one of the basic tools of human-computer interaction, and people usually have to use external force to control the computer and realize the operation of the computer. With the gradual development of science and technology, the human-computer interaction interface is becoming more and more friendly and convenient. In recent years, various new types of human-computer interaction systems have emerged in front of people, such as touch screens, data gloves, remote control handles, and bare hands. Among them, touch screens, data gloves, and remote control handles are widely used because of their high recognition rate and simple implementation. Used in business, games and other fields. The free-hand operation by recognizing gestur...
