METHOD OF THE NUMBERS MATRIX PROCESSING Russian patent published in 2018 - IPC G06T7/00 G06T7/90 G06K9/38 G06K9/46 

FIELD: image processing means.

SUBSTANCE: invention relates to the field of images binarization. Numbers A matrix with size of n×m elements processing method includes the A matrix elements threshold processing, in the process of which calculating the T1 and T2 thresholds values; comparing the A matrix elements numerical values with the T1 and T2 thresholds values; forming the B data array, into which entering each of the matrix elements in the A matrix location coordinates, which numerical value is either greater than the T1 threshold or less than the T2 threshold, wherein during the threshold processing, moving at least two windows of different size along the matrix, at that, performing the threshold processing at each window each position for located in the window the A matrix elements; and the binary image formation with the size of n×m points, guided by the rule: the binary image points having the same location coordinates as the A matrix elements, which coordinates are entered into the data array B, give the maximum brightness, and the binary image all other points are giving the background brightness.

EFFECT: increase in the small-size tracking objects detection probability with the other larger objects with very high or low brightness presence on the image.
