One-stage target detection algorithm based on

A, One-stage basic introduction

• CNN feature using convolution
• Immediate return of the object class probability and position coordinate values ​​(no region proposal)
• Low accuracy, speed is relatively fast two-stage

Two, One-stage basic process

One-stage and the difference Two-stage is that it contains the procedure recommended candidate region

One-stage common algorithm

• YOLOV1 / V2 / V3
• SSD / DSSD etc.
• Retina-Net
• …
