摘要： This disclosure relates generally to video analysis, and more particularly to systems and methods for mapping object co-ordinates from a video frame view to real world co-ordinates using perspective transformation. In one embodiment, a processor-implemented video frame coordinate transformation method is disclosed. The method may include obtaining an image from an image capture device and identifying, via one or more hardware processors, an object depicted in the image. Further, the method may include determining image-frame object coordinates for the object, and selecting one of a plurality of coordinate transformation matrices associated with the image capture device, based on the image-frame object coordinates for the object. Also, the method may include calculating, via the one or more hardware processors, real-world object coordinates for the object using the image-frame coordinates and the selected coordinate transformation matrix, and determining a trajectory of the object using the calculated real-world object coordinates.

摘要： A method, non-transitory computer readable medium, and productivity assessment computing device that identifies entities present in frames of a video. Entity movement across the frames is plotted to obtain a trajectory of the entities. Interactions of one or more of the entities in each of the frames are identified. A unique sequence encoding is generated for subtasks performed by each of the entities. One of the subtasks is classified as a waste subtask based on one or more of the interactions corresponding to the one of the subtasks and the trajectory and a type of each of the entities associated with the interactions. The sequence encodings of the one of the subtasks are correlated with a number of frames per second of the video to determine waste duration value(s) for a task and the waste duration value(s) are output.
摘要翻译：一种识别视频帧中存在的实体的方法，非暂时计算机可读介质和生产率评估计算设备。绘制跨框架的实体运动，以获得实体的轨迹。识别每个帧中的一个或多个实体的相互作用。为每个实体执行的子任务生成唯一的序列编码。基于与子任务和轨迹中的一个相对应的一个或多个交互以及与交互相关联的每个实体的类型，子任务之一被分类为废物子任务。子任务之一的序列编码与视频的每秒帧数相关，以确定任务的废弃持续时间值，并且输出废物持续时间值。

摘要： A method, non-transitory computer readable medium, and a data management computing device that assists with identifying relationship between entities includes including obtaining heterogeneous data associated with two or more primary entities from one or more data sources. Only relevant data associated with the two or more primary entities is identified from the obtained heterogeneous data. A masked relationship between the two or more primary entities is determined based on the identified relevant data and a generated entity relationship mapping. A related context for the determined masked relationship between the two or more primary entities are identified and provided.
