A Novel Hand Gesture Recognition Based on High-Level Features

Abstract: Gesture recognition plays an important role in human–computer interaction. However, most existing methods are complex and time-consuming, which limit the use of gesture recognition in real-time environments. In this paper, we propose a static gesture recognition system that combines depth information and skeleton data to classify gestures. Through feature fusion, hand digit gestures of 0–9 can be recognized accurately and efficiently. According to the experimental results, the proposed gesture recognition syst… Show more

“…The cascade extraction technique was used with a novel recursive connected component algorithm. Another study by Li et al [19] presented a developed system to combine depth information and skeletal data, facing the challenge of complex background and illumination variation, rotation invariance, in which some constraints were set in hand segmentation. Another study by Ma et al [5] improved depth threshold segmentation by combining depth and colour information using the hierarchical scan method, and then hand segmentation was used based on the local neighbour method.…”

“…In order to reduce the subsequent interference on the feature extraction of the gesture image, a gesture of elliptical model image segmentation is performed in the YCbCr color space expansion processing, and it can eliminate a small amount of holes in the gesture [34], the processing effect is shown in Figure 4 (a). Secondly, median filtering is performed, the contour of the gesture edge becomes very smooth [35], and the processing effect is shown in Figure 4(b).…”

“…al [16] proposed a gesture recognition system to segment the hand based on skin color and used K-means clustering and convex hull to identify hand contour and finally detect fingertips. Another study by Li et al [17] presents a developed system to combine depth information and skeletal data, facing the challenge of a complex background and illumination variation, rotation invariance, in which some constraints were set in hand segmentation. Marin et al [18] used two techniques together to detect finger regions such as leap motion and Kinect devices to extract different feature sets.…”

“…A threshold-based segmentation algorithm to z-axis was adopted to extract the hand mask. The resulting image was then smoothed by using a median filter [17]. The filtered image was combined with the cropped hand based on a joint tracking to improve the result of hand segmentation.…”
