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, based on the trajectory data of the trajectory of the object for the event within the video image data by dividing the video image data into a plurality of pixel regions, determining, for each pixel region of the plurality of pixel regions, whether the pixel region includes trajectory data, and encoding an indicator into the lossy searchable code based on the determining; 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.
