Abstract

The invention relates to the technical field of image processing, in particular to an image sharpening method, electronic equipment and a computer readable storage medium. The invention provides an image sharpening method, and the method mainly comprises the following steps: obtaining original image data which comprises a multispectral image and a panchromatic image which is completely registeredwith the multispectral image; preprocessing the original image data, and constructing a training set and a test set; constructing a high-frequency and low-frequency information separation and integration convolutional neural network model; training neural network model; when the loss error is greater than or equal to the loss error threshold, repeating the step S5 to the step S6; and when the losserror is smaller than the loss error threshold, obtaining an optimal neural network model.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to an image sharpening method, electronic equipment, and a computer-readable storage medium. Background technique [0002] Remote sensing images are increasingly being used in weather forecasting, vegetation analysis, geological exploration, ocean remote sensing, environmental detection, and urban planning. At the same time, with the mass promotion of commercial remote sensing image products, the demand for remote sensing images with both high spatial resolution and high spectral resolution is increasing. However, due to the limitations of the physical structure of optical imaging equipment, remote sensing systems often need to make a trade-off between the spatial resolution and spectral resolution of the image, and it is difficult to obtain remote sensing images with high spatial resolution and high spectral resolution through a single sensor. , instead pro...
