Method and apparatus for a reconfigurable multi-media system

A reconfigurable multi-media system, method and device provides monitoring and reconfiguration of a plurality of communication layers of a communications stack to dynamically reconfigure the modulation and coding of software defined radio (SDR). The system includes a software object radio (SWR) library having reconfigurable object specification, design and performance parameters, the SWR is adapted for at least one of transmitting and receiving multi-media content via wireless communication; a controller in communication with the SWR library; a power management device module in communication with said controller; a reconfigurable encoder/decoder in communication with said controller to provide the SWR with dynamic coding information for modulation; a TCP/IP interface in communication with said reconfigurable encoder/decoder and said controller; and an application layer comprising a link layer and a reconfigurable physical layer in communication with each other and said controller, the physical layer adapted for communication with a channel, and the application layer including at least one driver for multi-media delivery. The controller monitors the physical layer and link layer information and the reconfigurable encoder/decoder dynamically reconfigures modulation and coding of multi-media content according to a cross-layer optimization approach.

Shape representing and matching method for trademark image retrieval

ActiveCN104021229AResolve translationResolve scalingImage analysisSpecial data processing applicationsTrademarkShape matching
The invention discloses a shape representing and matching method for trademark image retrieval and relates to image search. The method comprises characteristic representation of trademark object shape and match of extracted characteristic, specifically comprising the following steps: 1) normalizing an object; 2) calculating the minimum circumscribed circle of the target object; 3) concentrically dividing a target region in equal area; 4) dividing the concentric circular region to blocks; 5) calculating and extracting characteristic; 6) generating corresponding binary shape characteristic string for each trademark object in a trademark library to match; and 7) judging the matching result of the binary shape characteristic string is a similarity numerical value in an interval of [0, 1]. The method can be directly applied to trademark image and further can be applied after dividing the trademark image to obtain the target object, so that the image is precisely matched in the object level, thereby effectively solving the problems of invariance of translation, rotation and rotation transformation of the target object in the shape matching process, more quickly and accurately searching for the target picture and reducing the trademark searching time and efficiently outputting the required target picture.

Family file processing method and device, computer equipment and storage medium

The invention relates to a family file processing method and device, computer equipment and a storage medium. The method comprises the steps of obtaining file attribute information and graphic information of family files; and respectively executing encryption operation on the file attribute information and the graphic information to generate an encrypted encrypted family file, wherein the file attribute information is used for representing an object specification in the family file; wherein the graphic information is used for representing visual features of the family files; therefore, when the encrypted family file is loaded into the project and is in a family editing mode; the file attribute information is encrypted; therefore, information such as object specifications in the family filecannot be obtained; the confidentiality of family files is realized; in addition, due to the fact that the graphic information is encrypted, normal geometric figures of the objects cannot be displayed in the family editing mode, users who are not allowed to check the geometric figures of the family files are prevented from imitating the geometric figures of the family files, the safety of the family files is greatly improved, and the loss of labor achievements of designers is avoided.

Software specification development assistance method and software specification development assistance device

A software specification development assistance method and a software specification development assistance device. The norm checking unit judges whether the two norms of the propositional form are contradictory or duplicative, with respect to the norm of the propositional form of the arbitrary checking object and the normative of the propositional form of the arbitrary comparison target acquired from the propositional rule storage unit, and if contradictory or duplicative, Then decompose the specification of the propositional form as the object of inspection into the specification of the propositional form that is contradictory or repeated with the specification of the propositional form of the comparison object, and the specification of the propositional form that is not contradictory or non-repetitive with the specification of the propositional form of the comparison object , registered in the inspection result storage unit, the decision table generating unit acquires either or both of the propositional-form specifications from the inspection-result storage unit, and fetches the condition part and the result of the propositional-form specification for each of the propositional-form specifications The row of the decision table is generated by using the section, and the display range is indicated in the column of the corresponding row of the column corresponding to the specification of the propositional form.
