Query: Edge-Cloud Collaborated Object Detection via Difficult-Case
  Discriminator   As one of the basic tasks of computer vision, object detection has been
widely used in many intelligent applications. However, object detection
algorithms are usually heavyweight in computation, hindering their
implementations on resource-constrained edge devices. Current edge-cloud
collaboration methods, such as CNN partition over Edge-cloud devices, are not
suitable for object detection since the huge data size of the intermediate
results will introduce extravagant communication costs. To address this
challenge, we propose a small-big model framework that deploys a big model in
the cloud and a small model on the edge devices. Upon receiving data, the edge
device operates a difficult-case discriminator to classify the images into easy
cases and difficult cases according to the specific semantics of the images.
The easy cases will be processed locally at the edge, and the difficult cases
will be uploaded to the cloud. Experimental results on the VOC, COCO, HELMET
datasets using two different object detection algorithms demonstrate that the
small-big model system can detect 94.01%-97.84% of objects with only about 50%
images uploaded to the cloud when using SSD. In addition, the small-big model
averagely reaches 91.22%- 92.52% end-to-end mAP of the scheme that uploading
all images to the cloud.
