Embodiment Construction

[0046] In order to enable those skilled in the art to better understand the technical solutions of the present application, the image processing method, object counting method and related devices provided in the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0047] In the process of image processing, all candidate frames belonging to the same target are generally determined by comparing the candidate frames, and then the detection frame of the target is determined based on all candidate frames of the same target. However, when the targets in the image to be processed are relatively dense, there will be a lot of overlap between the candidate boxes of two closely adjacent targets, so that all candidate boxes of one of the targets may be filtered according to the overlapping area or intersection ratio If all are filtered out, only the detection frame of one target will be confirmed in the end, which will aff...

Abstract

The invention provides an image processing method, a target counting method and related devices. The image processing method comprises the steps of performing feature extraction on a to-be-processed image to obtain a feature map of the to-be-processed image; extracting candidate feature maps from the feature maps; segmenting the candidate feature map to obtain a segmentation mask map of the candidate feature map; determining a plurality of segmentation mask graphs corresponding to the same target based on the target mask graph in the segmentation mask graphs; and taking one segmentation mask image in the plurality of segmentation mask images corresponding to the same target as a final segmentation mask image of the target. The method provided by the invention can improve the detection accuracy of the image when the targets in the to-be-processed image are dense.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image processing method, an object counting method and related devices. Background technique [0002] In the process of image processing, it is often necessary to detect the target in the image. In the long-term research and development process, the inventors of the present application found that the current image processing methods still have certain limitations, for example, the detection accuracy of the image is too low when the objects in the image to be processed are dense. Contents of the invention [0003] The present application provides an image processing method, a target counting method and related devices to solve the problem that the detection accuracy of the image is too low when the targets in the image to be processed are dense. [0004] In order to solve the above problems, the application provides an image processing method, the method c...
