The article is devoted with the use of the mechanism of detectors fields to increase the efficiency of 2D-dimensional discrete filtering. It is shown that the preliminary processing of the image by the detectors field reduces the dimensionality of the image transferred to the next stage of processing, and the use of the drift of the detectors field ensures resilience to scale of the image. The reduction in the volume of the processed digital array facilitates the realization of quasi-optimal filtering of the Wiener-Hopf type in real time. Varying the size of the structural elements of the detectors field allows, at the stage of quasi-optimal filtering, eliminate loss the target skip and false detection of objects. The stability of the detectors field to brightness variation after non-linear operations of dynamic range compression is investigated.
