METHOD FOR FILTERING UNINFORMATIVE ZONES ON VIDEO FRAME Russian patent published in 2024 - IPC G06V20/58 

FIELD: pattern recognition.

SUBSTANCE: result is achieved by the fact that at the first stage, an image received from a video camera as part of a wheeled robot enters RAM, Gaussian smoothing is performed for each of the image channels in the computing device with a predetermined window size, then a value for each of the channels is formed in each pixel of the smoothed image, locally averaged by Gaussian in a given size windows, an averaged image is formed, after which the modulus of the difference between the original and the averaged image is calculated, with the calculation of the modulus of deviation of the original signal in a pixel from the local average in the vicinity of this pixel, after which the multichannel image matrix is converted into a single-channel one with the maximum value across channels at the scale of a given window, adaptive binarization of the resulting single-channel matrix is performed using the Ocu method.

EFFECT: detecting the target trajectory and possible obstacles.
