Transferring execution from one instruction stream to another
InactiveUS20050086650A1Improve abilityReduce complexityGeneral purpose stored program computerSoftware simulation/interpretation/emulationInstruction setInstruction stream
A computer has instruction pipeline circuitry capable of executing two instruction set architectures (ISA's). A binary translator translates at least a selected portion of a computer program from a lower-performance one of the ISA's to a higher-performance one of the ISA's. Hardware initiates a query when about to execute a program region coded in the lower-performance ISA, to determine whether a higher-performance translation exists. If so, the about-to-be-executed instruction is aborted, and control transfers to the higher-performance translation. After execution of the higher-performance translation, execution of the lower-performance region is reestablished at a point downstream from the aborted instruction, in a context logically equivalent to that which would have prevailed had the code of the lower-performance region been allowed to proceed.

Three-dimensional wavelet based video fingerprinting
ActiveUS8094872B1Quickly and efficiently identifyImprove the display effectUser identity/authority verificationCharacter and pattern recognitionComputer graphics (images)Stop time
A method and system generates and compares fingerprints for videos in a video library. The video fingerprints provide a compact representation of the spatial and sequential characteristics of the video that can be used to quickly and efficiently identify video content. Because the fingerprints are based on spatial and sequential characteristics rather than exact bit sequences, visual content of videos can be effectively compared even when there are small differences between the videos in compression factors, source resolutions, start and stop times, frame rates, and so on. Comparison of video fingerprints can be used, for example, to search for and remove copyright protected videos from a video library. Further, duplicate videos can be detected and discarded in order to preserve storage space.

Controlling unmanned aerial vehicles to avoid obstacle collision
ActiveUS20170193830A1Simple and efficientObstacle collisionScene recognitionRemote controlled aircraftApparent SizeDistance sensors
A method, device, framework, and system provide the ability to control an unmanned aerial vehicle (UAV) to avoid obstacle collision. Range data of a real-world scene is acquired using range sensors (that provide depth data to visible objects). The range data is combined into an egospace representation (consisting of pixels in egospace). An apparent size of each of the visible objects is expanded based on a dimension of the UAV. An assigned destination in the real world scene based on world space is received and transformed into egospace coordinates in egospace. A trackable path from the UAV to the assigned destination through egospace that avoids collision with the visible objects (based on the expanded apparent sizes of each of the visible objects) is generated. Inputs that control the UAV to follow the trackable path are identified.

A model of a geometrical object comprising: bits in a first data structure encoded to identify a first set of elements from a collection of representations of geometrical shapes for a collection of elements and to represent positions of the elements by means of integer co-ordinates in a first system of co-ordinates; bits in a second data structure encoded to identify a second set of elements from said collection and to represent positions of the elements by means of integer co-ordinates in a second system of co-ordinates; bits in a third data structure encoded to represent a spatial transformation of the second system of co-ordinates relatively to the first system of co-ordinates. Thereby it is possible to create a very compact representation of a model of a geometrical object. The model-prima facia-seems to be constrained very hard, but is in fact a very flexible and easy to access model.

An encoded rhythmic pattern has several groups of velocity values, wherein the velocity values are sorted, such that the groups are included in sequence in an encoded rhythmic pattern. Now, the velocity values concentrated at the beginning of the encoded rhythmic pattern have a higher importance for characterizing the rhythmic gist of a piece of music than velocity values included in additional groups of velocity values. By using such an encoded rhythmic pattern, an efficient database access can be performed.
