Embodiment Construction

[0045] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0046] In the field of computer vision technology, in order to achieve accurate recognition of objects in images, images are often disassembled into multiple local candidate regions for understanding and learning. The principle of dismantling is to be able to cover as many objects of different sizes in the image as possible; each local candidate area can cover a part of the object, and does not have to completely contain the object,...

Abstract

The invention discloses a target recognition model training and target recognition method, device, and computing equipment, which belong to the technical field of computer vision, wherein the method includes: inputting a plurality of local candidate regions selected for the training image into the target recognition model, obtaining the preliminary results of the classification of multiple local candidate regions output by the target recognition model; performing local candidate region fusion according to the weak supervision information and the preliminary results of the classification of the multiple local candidate regions; according to the multiple The preliminary results of local candidate region classification and local candidate region fusion results correct the parameters of the target recognition model; iteratively execute the above training steps until the training results of the target recognition model meet a predetermined convergence condition. The solution of the present invention not only has direct supervision at the pixel level, but also can optimize the semantic segmentation model end-to-end, and can improve the result of target recognition based on the judgment of local candidate regions.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a target recognition model training and target recognition method and device, and computing equipment. Background technique [0002] Object recognition is a classic problem in the field of computer vision, where the purpose is to predict the location of a given object in an input image. A good object recognition scheme relies on the object category of each pixel to achieve accurate and dense image pixel-level understanding. The object recognition problem is usually very time-consuming because of the need to label the positions of all objects in the image. According to the practical experience of common methods, it usually takes 5-8 minutes to obtain an accurate target recognition label with a size of 400*600 pixels. Therefore, the speed and quality of data annotation has become an important issue that restricts the problem from obtaining big data support and further dev...
