Abstract: Disclosed are a method and an apparatus for handover between heterogeneous networks. The method comprises: obtaining, for each of a plurality of candidate networks, parameters of the candidate network including a packet loss rate and a network load, and taking the obtained parameters as decision parameters of the candidate network; obtaining each of preset service types and a preset weight factor for at least one user preference corresponding to the preset service type; calculating weights of decision parameters for each preset service type by using the decision parameters of the candidate network and through an Analytic Hierarchy Process, and determining a weight vector for the preset service type; adjusting the weight vector for each preset service type by using the preset weight factor; calculating, using the weight vector and through an intuitionistic trapezoidal fuzzy multi-attribute decision-making algorithm, a score for each of the candidate networks, determining the candidate network with the highest score as a target network, and triggering a handover.

Abstract: Embodiments of the present invention provide an end-to-end lightweight method and apparatus for license plate recognition. The method comprises: obtaining an image to be recognized; obtaining a number of a license plate in the image to be recognized and position coordinates of the license plate in the image to be recognized on the basis of the image to be recognized and a pre-trained target license plate recognition model, wherein the target license plate recognition model comprises a target feature extraction network, a target region candidate localization network, a target super-resolution generation network and a target recurrent neural network. Because in this solution, once an image to be recognized is input into the target license plate recognition model, the target license plate recognition model can output the license plate number and position coordinates of the license plate in the image to be recognized, one realizes an end-to-end model. The model has relatively strong robustness, and it can detect and recognize pictures taken under different camera angles. Moreover, computation variables such as image features can be reused without repeated computations, the model takes up less RAM and the speed of license plate recognition is greatly improved.
