Plate number, body color and mark identification-based equipment and plate number, body color and mark identification-based method for identifying fake plate vehicles

The invention discloses a plate number, body color and mark identification-based equipment and a plate number, body color and mark identification-based method for identifying fake plate vehicles. The equipment comprises a video detector, a plate number positioner, a plate number identifier, a body color identifier, a mark positioner, a mark identifier, a database query and alarm device and the like. According to the characteristic that the local edge information of the plate number image is rich, the equipment can accurately position a plate number in a captured image, extract a body region and a rough mark position by using the position of the plate number, and accurately extract a body color and a mark according to the extracted rough position; and then the equipment identifies the characters of the plate number, the body color and the mark, compares the results of the three identifications with data stored in a database to determine if a vehicle is a fake plate vehicle, and gives an automatic alarm for law enforcement officials to stop the vehicle for further check if the vehicle is a fake plate vehicle. The equipment is good in structure, simple in operation, high in judgment accuracy and few in manually set parameters. The equipment can also be used for catching escaped defaulting vehicles, stolen vehicles and peccancy vehicles and the like.

Method and system for valuing intangible assets

The present invention provides a method and system for valuing patent assets based on statistical survival analysis. An estimated value probability distribution curve is calculated for an identified group of patent assets using statistical analysis of PTO maintenance fee records. Expected valuations for individual patent assets are calculated based on a the value distribution curve and a comparative ranking or rating of individual patent assets relative to other patents in the group of identified patents. Patents having the highest percentile rankings would be correlated to the high end of the value distribution curve. Conversely, patents having the lowest percentile rankings would be correlated to the low end of the value distribution curve. Advantageously, such approach brings an added level of discipline to the overall valuation process in that the sum of individual patent valuations for a given patent population cannot exceed the total aggregate estimated value of all such patents. In this manner, fair and informative valuations can be provided based on the relative quality of the patent asset in question without need for comparative market data of other patents or patent portfolios, and without need for a demonstrated (or hypothetical) income streams for the patent in question. Estimated valuations are based simply on the allocation of a corresponding portion of the overall patent value “pie” as represented by each patents' relative ranking or position along a value distribution curve

Unmanned aerial vehicle landing landform image classification method based on DCT-CNN model

The invention discloses an unmanned aerial vehicle landing landform image classification method based on a DCT-CNN model. The method comprises the following steps of acquiring a training image set anda test image set of unmanned aerial vehicle landing landform images; carrying out DCT conversion on the unmanned aerial vehicle landing landform images and carrying out DCT coefficient screening; aiming at characteristics of complex unmanned aerial vehicle landing landform image scenes and abundant information, constructing a DCT-CNN network model; inputting a DCT coefficient of a training set into the improved DCT-CNN model so as to train, carrying out parameter updating on a network till that a loss function is converged into one small value, and then ending the training; taking a trainingimage characteristic set as a training sample so as to train a SVM classifier; and inputting a test set, using a trained model to carry out layer-by-layer learning on a test image, and finally inputting an acquired characteristic vector into the trained SVM classifier so as to carry out classification, and acquiring a classification result. In the invention, a data redundancy is reduced, trainingtime is greatly shortened, and classification accuracy of the unmanned aerial vehicle landing landform images is effectively increased.
