The invention relates to a scale adaptive kernel correlation filter fast target tracking method. According to the scale adaptive kernel correlation filter fast target tracking method, separation of afront background is promoted and a scale estimation module is added through introducing a two-dimensional variable bandwidth Gaussian window into a KCF framework, scale variations of a target are estimated according to a matching result of feature points of an image block, and whether the target is sheltered is judged by combining displacement prediction based on the scale variations. Once the target is sheltered, the user considers that no scale conversion occurs at the moment and template update is not performed, further the tracking precision is enhanced in this way. The scale adaptive kernel correlation filter fast target tracking method has the advantages of simple and fast calculation, and can significantly improve the calculation efficiency on the basis of compatible scale adaptation.

Embodiments disclosed herein provide a system and method useful for pre-processing non-sentence text extracted from business documents (e.g., malformed bulleted lists, runaway sentence identification, spatially separated data, etc.). One embodiment includes two heuristic algorithms: one searches for sentences in a document and another looks for non-sentences (e.g., lists, tables, tabs, names of people, addresses, etc.) in the same document. In one embodiment, when malformed text is encountered, a particular character (e.g., “?”) is inserted to signify to a natural language processing layer that this set of “words” represent a logical construct and should be evaluated independent of other sentences. Embodiments disclosed herein allow non-sentence text, which is linguistically dry but contextually rich, be included in the natural language processing. Embodiments disclosed herein also facilitate to reduce false positive concept extraction assertions by the natural language processing layer.
