Abstract We propose an improved a single-shot detector (SSD) algorithm to
detect falls of the elderly. The VGG16 network part of the SSD network is
replaced with the MobilenetV2 network. At the same time, we change the
infrastructure of MobilenetV2 network, the three layers that were not downsampled at the end were removed, which can make the model structure simpler
and faster to detect. The complete Intersection-over-Union (CIoU) loss function
is introduced to get a good regression of the target borders that have different
sizes and different proportions. We use Feature Pyramid Network (FPN) for upsampling, More >
