Target detection from image sequences using pixel-based decision criterion

In the pursuit of detecting ever smaller and dimmer object the track-before-detect methodology has been employed to integrate the target energy through a time sequence of frames. Current track-before-detect algorithms maintain a path statistic for each potential object trajectory. This set of trajectories is usually trimmed to keep the number of statistics manageable, and it becomes difficult to characterize the performance of the detector. In this paper we propose a pixel based statistic rather than a path based statistic and use it in a track-before-detect algorithm for a class of trajectories constrained only by a maximum target velocity.
