摘要： Unlike in the prior art in which the correspondence between a feature and a judgment value in an intended area is obtained by a single threshold value, the correspondence of the judgment value is obtained independently for each feature by use of a look-up table or the like. This makes it possible to achieve an accurate correspondence between the judgment value and the feature and thus to improve the high processing accuracy. Also, in the prior art, the judgment is repeated several times to secure the accuracy of the judgment and based on the total result thereof, the final judgment is made. Since the accuracy of each process is improved, however, the number of times the judgment is repeated is reduced for a higher processing speed.

摘要： Systems, methods, and computer readable storage media are described that can provide a multi-level hierarchical framework to progressively associate detection responses, in which different methods and models are adopted to improve tracking robustness. A modified transition matrix for the Hungarian algorithm can be used to solve the association problem that considers not only initialization, termination and transition of tracklets but also false alarm hypotheses. A Bayesian inference approach can be used to automatically estimate a scene structure model as the high-level knowledge for the long-range trajectory association.

摘要： A method for controlling a coiled tubing unit at a well site having a wellbore that extends downhole from a surface of the well site is provided. The method includes creating a coiled tubing simulation for performing a coiled tubing operation. The method further includes receiving wellbore data. The wellbore data includes downhole data collected using a downhole sensor downhole in the wellbore, and the downhole data includes a differential pressure measurement. The method further includes generating an automated coiled tubing control plan for the coiled tubing unit based at least in part on the wellbore data and the coiled tubing simulation. The method further includes controlling the coiled tubing unit using the automated coiled tubing control plan to regulate at least one of a rate-of-penetration of the coiled tubing unit or a weight-on-bit of the coiled tubing unit based at least in part on the differential pressure measurement.

摘要： A method for conducting a payment transaction using a smart wallet is proposed. The smart wallet accepts financial account information input by a consumer. The smart wallet stores the financial account information and transmits the financial account information to a smart wallet management server. When the consumer shops at a store, the smart wallet displays a list of merchandise purchased at the store and a total payment amount of the purchased merchandise. The smart wallet also provides a recommendation for making the payment amount. Finally, the smart wallet transmits a payment request to the smart wallet management server such that the payment is authorized and the payment transaction is completed. In one embodiment, the smart wallet can be used as a key to access shared mailboxes, resulting in significant improvement on package delivery operations for both couriers and consumers.

摘要： A preprocessing section binarizes input image data and calculates a total black pixel ratio. A feature extracting section detects connected components included in the binary image data and detects circumscribing bounding boxes of the connected components. Predetermined connected components are removed from all of the connected components based on the sizes of the detected circumscribing bounding boxes and bounding box black pixel ratios. By using the connected components that remain after removing the unnecessary connected components, a histogram is generated by specifying the sizes of the circumscribing bounding boxes as classes and numbers of the connected components as the frequencies of occurrence. A determining section determines whether the input image data is document image data or non-document image data based on information related to the generated histogram and the total black pixel ratio.
