Abstract

The invention relates to an image analysis method and device. The method is implemented through an analysis model. The model comprises a feature sharing module, a semantic segmentation module and an edge detection module. The method comprises the steps that feature extraction processing is carried out on an to-be-analyzed image through the feature sharing module, and shared features are acquired,wherein the shared features comprise feature information of a plurality of network depths; semantic segmentation processing and edge detection processing are carried out on the shared features throughthe semantic segmentation module and the edge detection module respectively, and a preliminary semantic segmentation result and a preliminary edge detection result of the to-be-analyzed image are obtained. According to the method and device, the shared features of the to-be-analyzed image can be extracted through the analysis model, and semantic segmentation processing and edge detection processing are carried out on the shared features to obtain the preliminary semantic segmentation result and the preliminary edge detection result, so that the consistency between a semantic segmentation result and an edge detection result is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to an image analysis method and device. Background technique [0002] With the rapid popularization of the Internet and the rise and development of e-commerce, image analysis technology based on computer vision has achieved unprecedented development. Analyzing objects in images (such as human bodies, animals, vehicles, etc.) and identifying various parts of objects (such as human heads, arms, clothing, etc.) is of great significance in the fields of video surveillance, character behavior analysis, etc. . [0003] In related technologies, the analysis of one or more objects in an image usually relies on object detection, and after the object in the image is detected, the object is analyzed. This method relies heavily on the object detection results, and there may be inconsistencies between the detection results and the segmentation (analysis) results, and the accuracy an...
