METHOD OF DETECTING OBJECTS Russian patent published in 2005 - IPC

FIELD: television systems.

SUBSTANCE: method comprises subtracting reference and current images, breaking the image series to be processed into fragments, and converting the characteristic features of the images into signals. The signals from one of the images are recorded as reference ones and are compared, e.g., by subtracting, with corresponding current signals, and, after the threshold processing, the difference signals obtained are converted into the binary signals for control of spatial filtration . As a result, the fragments of the current image, for which the control signals exceed the threshold, are transmitted, whereas the fragments, for which the signals are equal or less than the threshold value, are suppressed.

EFFECT: enhanced quality of the object image.
