DEVICE FOR RESTORING IMAGES IN QUATERNION SPACE USING ANISOTROPIC GRADIENT AND NEURAL NETWORK Russian patent published in 2021 - IPC G06F17/17 G06T11/00 G06N3/02 

FIELD: computer technology.

SUBSTANCE: invention relates to computer technology. The device for restoring images in the quaternion space using an anisotropic gradient and a neural network includes an image storage unit in the RGB space, an image conversion unit in the quaternion space, an image storage unit in the quaternion space, a pixel storage unit, a dictionary creation unit, a dictionary storage unit, a similarity search unit, a processing unit, an anisotropic gradient calculation unit, a priority calculation unit, an adaptive shape determination unit, a similarity search unit, a pixel evaluation unit using a neural network, the block of filling the image, the block of converting the image into the RGB space.

EFFECT: reducing the error of restoring color images by using the representation of the image in the space of hypercomplex numbers, an anisotropic gradient and a neural network.
