Small detector model comparison

2015:

single shot detector(SSD)

YOLO: you only look once

### Fast Yolo

  • 9 of 24 CNN layers from GoogleNet
  • fully connected detector network
  • real-time systems on PASCAL VOC 2007
  • 2016:

    YOLO9000(v2) :Better, Faster, Stronger

  • backbone: darknet-19(19 conv layers and 5 maxpooling layers)

    2017:

    Fast YOLO:

  • optimzided yolo v2 reduced parameters,evolutionary deep intelligence framework
  • introduce a motion-adaptive-inference method.(intuitively not very reliable)
  • 2018:

    YOLO v3:

  • backbone: Darknet-53(53 conv layers)
  • 1/2 fast as YOLO v2.

    YOLO-lite

  • just modify tiny yolo and see how it worked.

tiny ssd:

  • Inspired by the **Fire microarchitecture ** from SqueezeNet. First subnet stack of Tiny SSD as a standard convolutional layer followed by a set of highly optimized Fire modules.
  • determine the ideal number of Fire modules as well as the ideal microarchitecture.
  • determined empirically that 10 Fire modules provide strong object detection performance
  • feature layer:
  • result
  • half precision floating-point parameters.

    2019:

    EfficientDet

  • speed: same level as yolo3

# 2020: ## YOLO v4:

#THings need checking out: small backbone: SqueezeNet, ShuffleNet Two_stage detection head:

  • RCNN,fast-RCNN,faster-RCNN One stage detection:
  • retinaNet Neck layers:
  • PAN,FPN,BiFPN

  • what exactly is receptive field?
