Embodiment Construction

[0029] like figure 1 As shown, the steps of the real-time gesture recognition method based on finger segmentation are as follows:

[0030] Step 1: Hand Region Detection

[0031] like figure 2 As shown, a general network camera is used as an input device for gesture image acquisition. Since the background is single, the method of background subtraction is used for hand area detection. In order to prevent noise interference in the background, the skin color information of the HSV color space is used, and the specific space values ​​​​used are H:315, S:94, V:37. image 3 For the determined hand area, the image size is resized to 200*200 at the same time.

[0032] Step 2: Palm Finger Segmentation

[0033] First use the distance transformation to find the center point of the palm. The distance transform here can also be called distance mapping. Record the distance between each pixel in the hand area and the boundary pixels on the distance transformation map. like Figure 4...

Abstract

The invention discloses a real-time gesture recognition method based on finger division and relates to a novel gesture recognition technology. The gesture recognition technology is one of hot topics in the human-computer interaction field. The real-time gesture recognition method based on finger division comprises the steps of extracting the whole hand region through a background subtraction method, and dividing a palm part and a finger part on the extracted hand region; judging finger types according to positions, angles and other information of fingers; performing gesture recognition on the whole gesture through a rule classifier. Related gesture recognition tests performed through a large number of experimental images prove that the real-time gesture recognition method based on finger division is high in speed and efficiency, and real-time effect can be achieved.

Description

technical field [0001] The invention mainly relates to gesture recognition technology, in particular to a real-time gesture recognition method based on finger segmentation. Background technique [0002] Vision-based gesture recognition technology is a very important content in human-computer interaction (HCI). For more than a decade, the keyboard and mouse have been an important medium for human-computer interaction. However, with the rapid development of hardware and software, there are higher requirements for HCI methods. In particular, speech recognition and action recognition technologies have received a lot of attention in the field of HCI. [0003] Movements are bodily actions or expressions of emotion. This includes body posture and gestures. It can be divided into two categories: static actions and dynamic actions. For the former, the gesture or gesture of the body is a sign. For the latter, body or hand movements express some important information. Gestures c...
