Title:
オプティカルフロー推定方法
Document Type and Number:
Japanese Patent JP3557982
Kind Code:
B2
Abstract:
Method for estimating the optical flow between images includes obtaining a motion orientation component and a motion magnitude component. Determining the motion orientation component includes creating, a graph using spatio-temporal derivatives of the images, solving for a maximum-flow in the graph to obtain a first minimum-cut through it, and computing the motion orientation component from the minimum-cut. Determining the motion magnitude component includes creating a second graph using spatio-temporal derivatives of the images and the motion orientation component, solving for a second maximum-flow in the second graph to obtain a second minimum-cut through it, and computing the motion magnitude component from the second minimum-cut. The motion orientation component and the motion magnitude component together comprise the estimate of the optical flow between the images.
