Abstract
Object detection has been studied for many years. The convolutional
neural network has made great progress in the accuracy and speed of object
detection. However, due to the low resolution of small objects and the
representation of fuzzy features, one of the challenges now is how to effectively
detect small objects in images. Existing target detectors for small objects: one is
to use high-resolution images as input, the other is to increase the depth of the
CNN network, but these two methods will undoubtedly increase the cost of
calculation and time-consuming. In this paper, based on the RefineDet network
framework, we propose our network structure RF2Det by introducing Receptive
Field Block to solve the problem of small object detection, so as to achieve the
balance of speed and accuracy. At the same time, we propose a Medium-level
Feature Pyramid Networks, which combines appropriate high-level context
features with low-level features, so that the network can use the features of both
the low-level and the high-level for multi-scale target detection, and the accuracy
of the small target detection task based on the low-level features is improved.
Extensive experiments on the MS COCO dataset demonstrate that compared to
other most advanced methods, our proposed method shows significant
performance improvement in the detection of small objects.
