AI Technical Summary

Technical Problem

The pre-trained model generated by the existing comparative learning self-supervised algorithm is directly migrated to the downstream object detection task, resulting in poor object detection effect.

Method used

By acquiring the sample image and generating a plurality of input images, inputting to the preset first model and the second model, the feature representations of comparison loss and positioning loss are calculated, and the model is trained to generate a pretrained model. This pre-trained model can not only learn the ability to characterize the target, but also learn the ability to position the target.

Benefits of technology

Improve the accuracy of target detection results and improve the target detection effect.
