Abstract

The invention discloses a method and system for converting an anchor-free algorithm into an anchor-based algorithm, and the method comprises the steps: 1, calculating all grid information in the anchor-free algorithm, and obtaining a predicted value of the anchor-free algorithm; step 2, according to a specific rule of generating anchors by an anchor-based algorithm, generating anchors of which the shape and the number are the same as those of grids in the anchor-free algorithm, and according to the anchor-based algorithm, generating anchors of which the shape and the number are the same as those of grids in the anchor-free algorithm; step 3, according to the grid predicted value of the anchor-free algorithm and the anchor predicted value of the anchor-based algorithm, establishing a conversion relation for converting the anchor-free algorithm into the anchor-based algorithm; and step 4, according to the conversion relationship, setting a corresponding layer in the neural network, and realizing conversion of the anchor-free predicted value into an anchor-based predicted value. According to the method, the anchor-free algorithm can be deployed more quickly, the anchor-free algorithm and the anchor-based algorithm are unified into one set of operation, and subsequent application and use are facilitated.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for converting an anchor-free algorithm into an anchor-based algorithm. Background technique [0002] In the field of image processing, object detection has always been the most researched and widely used branch direction. In traditional image algorithms, sliding window technology, support vector machine and other means are used to find the position of the target. Taking RCNN as a starting point, deep learning technology has also had a huge impact in the direction of object detection. [0003] The deep learning technology in the field of target detection can be divided into different types from different perspectives: from the perspective of model structure, it is divided into one-stage algorithm and two-stage algorithm; from the perspective of whether it is based on anchor frame, it can be divided into anchor-based algorithm and anchor-free algorit...
