Hand gesture recognition for cursor control

A system for hand gesture recognition is described herein. The system includes a display, camera, memory, and processor. The memory is to store instructions and is communicatively coupled to the camera and the display. The processor is communicatively coupled to the camera, the display, and the memory. When the processor is to execute the instructions, the processor is to estimate one or more motion vectors of an object using a pair of consecutive frames and estimate an average motion vector of the object. The processor is also to obtain a descriptor based on histogram values from a histogramof optical flow (HOOF) of the one or more motion vectors and the average motion vector and classify the descriptor as a gesture. 本文中描述了用于手势识别的系统。系统包含显示器、摄像机、存储器和处理器。存储器将存储指令并且通信地被耦合到摄像机和显示器。处理器通信地被耦合到摄像机、显示器和存储器。在处理器将执行指令时，处理器将使用对连续帧来估计对象的个或多个运动向量，并且估计对象的平均运动向量。处理器也将基于来自个或多个运动向量的光流的直方图（HOOF）的直方图值和平均运动向量来获得描述符，并且将描述符分类为姿势。
