Claim One:
1. An apparatus comprising: a processor; and memory storing modules; wherein said processor executes said stored modules and performing image-based tracking of surveillance objects in front of a scene background in a surveillance scene; and wherein said stored modules comprise: an object segmentation module, stored in said memory, ascertaining moving object areas in front of the scene background; an administration module, stored in said memory, assigning surveillance objects to the moving object areas, detecting a fusion of two or more surveillance objects, and making them jointly as an object group; and a feature detection module, stored in said memory, determining local features for tracking the surveillance objects of the object group only, in image areas defined by the moving object areas, wherein said local features comprise features ascertained by evaluating a partial area of the moving object areas, the image areas, or both the object areas and image areas prior the fusion of the two or more objects as the object group, and wherein said local features are features selected from the group consisting of textures, distribution of brightness, Kanade-Lucas-Tomasi (KLT) features, and Scale-Invariant-Feature-Transform (SIFT) features, or any combination thereof.
