Some special digital operators and recognition techniques are presented for digital image processing. Two complete digital systems are described. The first fast and relatively simple system uses non-linear smoothing and adaptive thresholding as a pre-processing and inertial invariant components to recognize moving objects. The second more complex system uses non-linear smoothing, edge detection and noise spike reduction as a pre-processing and FFT of the boundary distances from the centroid to recognize and track moving objects. Experiments of recognition and tracking of mechanical objects are reported.
