Abstract: The present invention discloses an epitaxial structure for semiconductor light-emitting device, comprising an electron injection region, a hole injection region, a multi-quantum well active region, a potential barrier layer for blocking carriers, and one or more band edge shaping layers. The doping type and/or doping concentration of said band edge shaping layers are different from those of the adjacent layers. It may trim the band edge shape of the semiconductor energy band through the local built-in electric field formed as a result of adjusting the doping type, doping concentration and/or layer thickness thereof, such that the carriers in the multi-quantum well active region are distributed uniformly, the overall Auger recombination is decreased, and the effective potential barrier height of the potential barrier layer for blocking carriers is increased to reduce the drain current formed by carriers overflowing out of the multi-quantum well active region, thereby improving internal quantum efficiency. The present invention further discloses a semiconductor light-emitting device that employs said epitaxial structure, which similarly achieves the effects of reduced Auger recombination and/or decreased drain current through the trimming of the band edge shape of the energy band structure by the local built-in electric field, thereby improving internal quantum efficiency of the device.

Abstract: The present invention provides a medical image segmentation method based on a Boosting-Unet segmentation network. By dividing training of an overall segmentation network into training of m sub segmentation networks, the method inherits convolution kernel parameters of the (k−1)th sub segmentation network during training of the kth sub segmentation network, thereby greatly decreasing the quantity of the convolution kernel parameters during every training and improving the learning ability of the network and the resistance to noise and image blur. In addition, a plurality of sub segmentation networks are arranged, so that the efficiency of the network is improved, a depth of an image data feature is also extracted, and the image data is segmented precisely, thereby improving the learning ability of the overall segmentation network to the image data feature, enhancing the robustness to noise disturbance information and further improving the performance of image segmentation.
