Abstract

Claims (29)

1. A system for lossy image and video compression utilizing a metanetwork, comprising:

a metanetwork engine comprising a processor, a memory, and a first plurality of programming instructions stored in the memory, wherein the first plurality of programming instructions, when operating on the processor, cause the processor to:

receive a desired image;

receive a noise image;

receive a set of training images;

using the set of training images, train a plurality of neural networks to reconstruct each of the set of training images by mapping the noise image to each of the set of training images;

store the parameters for each of the plurality of neural networks as a set of metanetwork hyperparameters;

use the set of metanetwork hyperparameters as operating parameters for each of the plurality of neural networks;

use the plurality of neural networks to map the noise image to the desired image, producing a second set of hyperparameters corresponding to the specific filters produced from the operation of each of the plurality of neural networks, such that the second set of hyperparameters, when applied to the noise image using the neural network, produce an approximation of the desired image within an error that is less than a pre-determined threshold; and

store the second set of hyperparameters for use in future image mapping operations.

2. The system of claim 1 , wherein each of the plurality of neural networks:

generates at least one convolutional filter, wherein the noise image may be filtered through all convolutional filters in succession, mapping it to an approximation of a desired image; and

storing the second set of hyperparameters for use in future image mapping operations.

6. The method of claim 5 , further comprising the steps of:

Generating, at each of the plurality of neural networks, at least one convolutional filter, wherein a noise image may be filtered through the convolutional filters in succession, mapping it to an approximation of a desired image, using a plurality of neural meta-networks; and
