Abstract

The invention relates to the technical field of data processing, in particular to a data processing method, a data processing device, a computer readable medium and electronic equipment. The method comprises the steps of obtaining a to-be-processed feature map, and inputting the feature map into an expansion rate calculation layer to obtain an expansion rate table corresponding to the feature map,wherein the expansion rate table comprises expansion rate values corresponding to all pixels in the feature map; and inputting the expansion rate table into an expansion convolution layer to enable the expansion convolution layer to perform expansion convolution processing on the feature map in combination with the expansion rate table so as to obtain feature data corresponding to the feature map. According to the method, the receptive field of each pixel in the feature map can be adaptively and finely adjusted, and feature omission in the feature extraction process is avoided, the sampling density can be improved, and detail features are reserved.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a data processing method, a data processing device, a computer-readable medium, and an electronic device. Background technique [0002] When using deep learning algorithms for image processing, expanding the receptive field helps the neural network to receive a wider range of information and extract more complex information. Generally speaking, a conventional way to expand the receptive field is to increase the number of layers of the neural network, and the deeper the network layer, the wider the information it receives. However, its disadvantage is that it greatly increases the complexity of the network, and the difficulty of convergence increases accordingly. Another way to expand the convolution is to expand the receptive field by expanding the size of the filter. However, its defect is that some pixels are regularly skipped during the convolution opera...
