Coding scheme for identifying spatial locations of events within video image data

A system for generating a coding scheme for identifying a spatial location of an event within video image data comprising:

• at least one processing unit;
• memory operably associated with the at least one processing unit;
• and
• a spatial representation tool storable in memory and executable by the at least one processing unit, the spatial representation tool comprising a compression component configured to:
• receive trajectory data of a trajectory of an object for an event within video image data;
• generate a lossless compressed contour-coded blob to encode the trajectory data of the trajectory of the object for the event within video image data;
• generate a lossy searchable code, which corresponds to the lossless compressed contour-coded blob and is not in the video image data, of the trajectory of the object for the event within the video image data;
• convert a region of interest within the video image data to a lossy query code, the region of interest corresponding to a sub-section of a visual display output of the video image data;
• and
• compare the lossy query code to the lossy searchable code within a relational database to identify a corresponding lossless trajectory data of the trajectory of the object for the event within the video image data.

A computer-readable storage-device that is not a signal and stores computer instructions, which when executed, enables a computer system to generate a coding scheme for identifying a spatial location of an event within video image data, the computer instructions 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, which corresponds to the lossless compressed contour-coded blob and is not in the video image data, of the trajectory data of the trajectory of the object for the event within the region of interest;
• converting a region of interest within the video image data to a lossy query code, the region of interest corresponding to a sub-section of a visual display output of the video image data;
• and
• comparing the lossy query code to the lossy searchable code within a relational database to identify a corresponding lossless trajectory data of the trajectory of the object for the event within the video image data.
