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, 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.
