Abstract: Disclosed in the present invention is a rare-earth doped semiconductor material. Compounds of two rare-earth elements R and R′ having different functions are introduced into an indium oxide containing material. The coupling of R element ions to an O2p orbit can effectively enhance the transfer efficiency of the rare-earth R′ as a photogenerated electron transfer center, such that the light stability of a device with a small amount of R′ doping can be achieved. Compared with single rare-earth element R′ doping, due to less doping, the impact on a mobility is less, such that higher mobility and light stability devices can be obtained. Further provided in the present invention is a semiconductor-based thin-film transistor, and an application.

Abstract: The present invention discloses a method for automatic segmentation of a fuzzy boundary image based on active contour and deep learning. In the method, firstly, a fuzzy boundary image is segmented using a deep convolutional neural network model to obtain an initial segmentation result; then, a contour of a region inside the image segmented using the deep convolutional neural network model is used as an initialized contour and a contour constraint of an active contour model; and the active contour model drives, through image characteristics of a surrounding region of each contour point, the contour to move towards a target edge to derive an accurate segmentation line between a target region and other background regions. The present invention introduces an active contour model on the basis of a deep convolutional neural network model to further refine a segmentation result of a fuzzy boundary image, which has the capability of segmenting a fuzzy boundary in the image, thus further improving the accuracy of segmentation of the fuzzy boundary image.
