Embodiment Construction

[0028] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0029] refer to figure 1 , the present invention provides a hand shape input method, which is a gesture recognition method based on vision. Its ultimate goal is to use computer vision, image processing and pattern recognition technology to recognize the hand shape of bare hands in a natural environment and take the user as the center. Confirm to complete the mobile phone / computer character input.

Abstract

The invention discloses a handshape input method. The mobile phone camera is used to collect hand-shaped motion video, and the video data stream is processed synchronously in the background. The number of resampled images per second is designed to judge whether the input partitioned hand is present or not, and the partitioned hand is used to re-segment the data. The input hand-shaped motion videoafter the partitioned hand is recognized is divided into a series of input hand-shaped photo sequences. Photo sequences collected from hand-shape input video motion are used for skin color recognition, hand-shape core region size adjustment, color space conversion and image sequence generation, and then the positional relationship between thumb and other fingers in the image is judged according tothe initial predetermined image characteristics, thus completing left-right hand recognition and hand shape judgement. The invention relates to a coding method for inputting various symbols into a computer or other equipment by using a hand shape, which is convenient for human-computer interaction application under special crowds and special situations.

Description

technical field [0001] The invention relates to the field of human-computer interaction applications, in particular to a hand shape input method. Background technique [0002] Input Method (Input Method) refers to the input coding method rather than the software that realizes text input. The input method generally refers to the input method of the ordinary keyboard of the computer or the keyboard on the mobile phone. In a broad sense, the input method also includes handwriting, voice, OCR (Optical Character Recognition, optical character recognition) scanning reader, speed recorder and other input methods. Handwriting recognition utilizes the computer's word recognition function to identify text or other symbols from the user's handwritten characters. Speech recognition uses a microphone and speech recognition software to interpret text. There are many types of OCR software, such as Tsinghua OCR, which is commonly used. After the system recognizes the graphics, the system ...
