Abstract: 一种基于生物识别的手势识别方法、装置、计算机设备及存储介质，方法包括：获取待识别图像（S201）；将待识别图像输入目标检测网络，得到手部特征图像（S202）；确定手部特征图像中的二维关节点，得到标注有二维关节点的若干热力图（S203）；通过三维修正模型修正若干热力图中的二维关节点，得到二维关节点拓扑图（S204）；对二维关节点拓扑图进行图卷积，得到待识别图像中的手势类别（S205）；其中，手势类别可存储于区块链中。该方法提高了手势识别的准确性。

Abstract: A system for detecting scan and non-scan events in a self-check out (SCO) process includes a a scanner for scanning objects and generating point of sale (POS) data, a video camera for generating a video of the scanning region, proximity sensors proximal to the video camera for defining an Area of Action (AoA), wherein the video camera starts capturing scanning region, when the objects enter the AoA, and the POS data includes non-zero values, an Artificial neural network (ANN) for receiving an image frame and generating one or more values, each indicating a probability of classification of the image frame into one or more classes respectively, and a processing unit for processing the POS data, and probabilities of one or more classes to detect a correlation between video data and POS data, and detect one of: scan and non-scan event in the image frame based on the correlation.

Abstract: A system that analyzes an image of a gaming area, identifies an object depicted in the image and generates a virtual mask that conforms to a shape of the object. The system further maps the virtual mask to locations in a virtual scene that correspond to pixels in the image that correspond to the outer shape of the object. The system renders content in the virtual scene relative to a boundary of the mask based on the relevance of the physical object to the game state. The system instructs a projector to project the rendered image in relation to the physical object according to the content rendered relative to the mask.
