Saliency compression method and system, storage medium, computer equipment and application

Abstract

The invention belongs to the technical field of image compression, and discloses a saliency compression method and system, a storage medium, computer equipment and application, and the method comprises the following steps: for a saliency detection module, employing a U2Net network to achieve the saliency detection module; comparing a residual block fusion local feature with a multi-scale feature, and proposing an overall network architecture; according to the U-Net and the non-local residual error, proposing ResU to extract multi-scale features in the stage; inputting a convolutional layer, and converting the original feature map into an intermediate map F1 (x) through a common convolutional layer; learning and coding multi-scale context information through U-block by taking the intermediate feature map F1 (x) as input; fusing local features and multi-scale features through F1 (x) and U (F1 (x)); for a compression module, proposing an attention channel method, so that a discrete Gaussian model is improved, and finally decoder enhancement is introduced to realize construction of an image compression architecture. According to the invention, the compression quality of the image can be improved at a low bit rate.

Description

Technical field [0001] The present invention belongs to the field of image compression, and more particularly to a method, system, storage medium, computer device, and application of a significant compression. Background technique [0002] Currently, although the amount of data in the picture is large, not all content contains user interest. People often pay more attention to the goal in typical application scenarios. The identification problem of the significant target is particularly important under the conditions of bandwidth limit. The global compression method will make some important details of the significant region, such as license plate numbers, indications, etc. The compression ratio of the significant region can reduce the compression ratio of the significant region, improve the compression magnification of the irrelevant information such as the background, and under the same picture compression, the information that is interested in users can be reserved as much as po...
