System and method for transforming video data into directional object count
The present invention is a computer-implemented system and method for transforming video data into directional object counts. The method of transforming video data is uniquely efficient in that it uses only a single column or row of pixels in a video camera to define the background from a moving object, count the number of objects and determine their direction. By taking an image of a single column or row every frame and concatenating them together, the result is an image of the object that has passed, referred to herein as a sweep image. In order to determine the direction, two different methods can be used. Method one involves constructing another image using the same method. The two images are then compared, and the direction is determined by the location of the object in the second image compared to the location of the object in the first image. Due to this recording method, elongation or compression of the objects can occur because of acceleration or deceleration of the objects and can be uniquely utilized to determine the speed or movement path of the objects. The second method of determining direction involves comparing the object in the image to an established marker. The transformations can also be used to produce labeled data for training machine learning models: bounding-boxes provided in sweep image can be transformed to bound boxes in video, and boxes in video can be transformed into boxes in the sweep image. |

Event prioritization for an ordered event stream
Event prioritization for an ordered event stream (OES) is disclosed. Unlike conventional prioritization techniques, the disclosed subject matter can be performed by an OES data storage system to provide direct, rather than indirect, control of prioritization. In an embodiment, a prioritized hashed key (PHK) can be determined from an event characteristic and an indicated event priority value based on a selectable priority-sensitive hashing function. As such, events with a same key characteristic but different indicated priorities can have different PHKs, events with different key characteristics but the same indicated priority can have different PHKs, and events with the same key characteristic and the same priority can have a same PHK. An event priority can be inherently comprised in the PHK without needing to explicitly store the priority value with a written event in the OES. Moreover, the disclosed prioritization for the OES can be compatible with OES scaling techniques. |

Method for determining functional safety of reset, and electronic device for executing same
In order to determine whether a reset function of an electronic device is safe, the states of a first checker and a second checker are toggled to preset states when a reset root is received from an external device. When a release of a local reset is received, whether the local reset was normally released is determined on the basis of a system clock. When the local reset is not normally released, the state of the second checker is toggled, and when the final local reset among the local resets is normally released, the state of the first checker is toggled. The release states of the local resets are monitored on the basis of the state of the first checker and the state of the second checker. |

Performance scaling for binary translation
Embodiments relate to improving user experiences when executing binary code that has been translated from other binary code. Binary code (instructions) for a source instruction set architecture (ISA) cannot natively execute on a processor that implements a target ISA. The instructions in the source ISA are binary-translated to instructions in the target ISA and are executed on the processor. The overhead of performing binary translation and/or the overhead of executing binary-translated code are compensated for by increasing the speed at which the translated code is executed, relative to non-translated code. Translated code may be executed on hardware that has one or more power-performance parameters of the processor set to increase the performance of the processor with respect to the translated code. The increase in power-performance for translated code may be proportional to the degree of translation overhead. |
