Classification: CPC G | IPC G

Claim 14:
15. A non-transitory computer readable storage medium storing computer readable instructions, wherein, the computer readable instructions, when executed by a processor, are configured to cause the processor to perform:
acquiring a to-be-detected medical image comprising a plurality of slices;
for each slice in the to-be-detected medical image:
extracting N basic feature maps of the slice by a deep neural network, N being an integer greater than 1,
merging features of the N basic feature maps of the slice by the deep neural network, to obtain M enhanced feature maps of the slice, M being an integer greater than 1, and
respectively performing a hierarchically dilated convolutions operation on the M enhanced feature maps of the slice by the deep neural network, to generate a superposed feature map of each enhanced feature map of the slice; and

predicting position information of a region of interest and a confidence score thereof in the to-be-detected medical image by the deep neural network based on the superposed feature map of each slice in the to-be-detected medical image.
