Abstract:
1. A method for generating a coding scheme for identifying a spatial location of an event within video image data comprising: receiving trajectory data of a trajectory of an object for an event within video image data; generating a lossless compressed contour-coded blob to encode the trajectory data of the trajectory of an object for the event within the video image data; generating a lossy searchable code of the trajectory data of the trajectory of the object for the event within the region of interest to enable searching of a relational database based on the trajectory data of the trajectory of the object for the event within the video image data; specifying, via a user input, a region of interest corresponding to a subsection of a visual display output of the video image data; converting the region of interest within the video image data to a lossy query code; and comparing the lossy query code to the lossy searchable code within the relational database to identify the corresponding lossless trajectory data of the trajectory of the object for the event within the video image data.
