A mutil-feature fusion algorithm for Mammography masses

Abstract： Aiming at the problem of the high probability of miss and false positive rates in single-view Mammography, an improved automatic detection algorithm is proposed in this paper. The dilated residual network (DRN) combined with a modified feature pyramid network (FPN) is used for the detection of breast masses. The expansion convolution in DRN is used to reduce the number of downsampling of images. The number of layers of the DRN is also increased to satisfy the required input of the FPN. In the FPN structure, the attention mechanism is used to reduce the information loss caused by the direct fusion of different feature maps, while dense connections are used instead of the original lateral connections to make full use of the location and detailed information on the target for the shallow features. Simulation experiments show that the detection accuracy of the designed model on the CBSI-DDSM dataset is improved by 7.1 percent compared to the baseline.
