Abstract

The invention discloses an image recognition method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of a, obtaining a first globalenergy function of an image, wherein the first global energy function comprises a prior energy data item and a local energy data item; b, optimizing the first global energy function to obtain an intermediate recognition result of the image; and c, judging whether the intermediate recognition result is converged or not, if so, determining the intermediate recognition result as a final recognition result of the image, otherwise, updating the local probability of each pixel point of the image corresponding to each label according to the intermediate recognition result, and executing the step a. The embodiment of the invention has relatively high robustness and space-time smoothness.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image recognition method and device. Background technique [0002] Road segmentation belongs to scene semantic analysis technology, which is to segment road areas from images or laser point cloud data. Road segmentation can be applied to road texture maps in street scene simulation, road vector element extraction in high-definition map generation, and auxiliary unmanned vehicles. Autopilot. [0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: due to the complexity and variety of road scenes, the illumination and occlusion in different road scenes are usually quite different, and sometimes there are road scenes with similar foreground and background. Under the influence of these factors, the existing image recognition methods have the shortcomings of insufficient robustness wh...
