摘要： The invention relates to a method for detecting objects on a pixel plane. Said movable object detection is frequently possible only by tracking the pre-segmented objects or the parts thereof. in this relation, the spatially adjacent objects often provoke problems, in particular in the case when a camera system or more precisely an observer is movable. The inventive method consists in determining a two-dimensional position of the relevant pixels inside a first image and in determining an associated remote value for each relevant pixel. Said pixels are tracked and localized on two ore more successive images, wherein the two-dimensional position or the pixel offset and the associated remote value are again determined for each pixel. The position and movement of the relevant pixels are also determined with the aid of a suitable filter. Finally, the relevant pixels are combined into objects under predefined conditions with respect to the position, moving direction and motion ratio thereof.
