Problems solved by technology

[0003] Usually, the feature map is upsampled. When it is necessary to obtain the upsampled feature map with the target spatial resolution, the feature map with low spatial resolution is directly used for linear interpolation or deconvolution. The only information that can be used in this way is the one with The feature map itself with low spatial resolution, and the detail information in the feature map at this time is very little, making it difficult to obtain more detailed features from the upsampling feature map, that is, the upsampling feature map is blurred

Abstract

The embodiment of the invention provides an image processing method and device, electronic equipment and a computer readable storage medium, and belongs to the field of image processing, and the method comprises the steps of obtaining at least two feature maps with different spatial resolutions based on a to-be-processed image; and carrying out at least one wavelet analysis based on the at least two feature maps to obtain an up-sampling feature map with the target spatial resolution. Based on the scheme provided by the embodiment of the invention, the up-sampling feature map can be obtained by combining the features of the at least two feature maps with different spatial resolutions, so that the obtained up-sampling feature map has more detail features, and the image is clearer.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, the present application relates to an image processing method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] With the development of computer vision and artificial intelligence, when processing images, such as depth estimation, semantic segmentation and normal vector estimation, it is necessary to upsample the feature map. Upsampling of feature maps refers to the process of upgrading feature maps with low spatial resolution to feature maps with higher spatial resolution. More detailed feature maps can be obtained through upsampling algorithms. [0003] Usually, the feature map is upsampled. When it is necessary to obtain the upsampled feature map with the target spatial resolution, the feature map with low spatial resolution is directly used for linear interpolation or deconvolution. The only information tha...
