Classification: CPC G  H | IPC G  H

Claim 20:
21. A method, comprising:
generating a first feature map of a first image by a first layer of a neural network, the neural network executing on a computer processor to encode the first image at a defined bitrate;
computing, by an attention layer of the neural network based on the first feature map of the first image, an adaptive spatial saliency map for the first feature map of the first image, wherein a sum of all values of the adaptive spatial saliency map equals one; and
performing an element-wise multiplication of the first feature map and the adaptive spatial saliency map for the first feature map to generate a modulated feature map to encode the first image, the modulated feature map to have relatively higher activations on portions of the first image that are higher regions of interest to a human visual system (HVS) and relatively lower activations on portions of the first image that are lower regions of interest to the HVS while keeping the defined bitrate constant.
