Abstract

The invention discloses an image processing method and device, which relate to the field of remote sensing images. The image processing method of the present invention includes: performing passivation and blurring processing on the first image; performing various special-shaped diffusion on the first image after the passivation and blurring processing, so as to smooth the noise in all directions of the first image; The first image after the special-shaped diffusion processing is copied to obtain a second image; the two-dimensional discrete wavelet transform is performed on the first image after the special-shaped diffusion processing to obtain the first high-frequency sub-image and the first low-frequency sub-image, Perform two-dimensional discrete wavelet transform on the second image to obtain a second high-frequency sub-image and a second low-frequency sub-image; The sub-image, the second high-frequency sub-image and the second low-frequency sub-image are fused to obtain a fused image. The invention can be widely used in the scene of processing remote sensing images.

Description

technical field [0001] The invention relates to the field of remote sensing images, in particular to an image processing method and device. Background technique [0002] Remote sensing images are films or photos that record the magnitude of electromagnetic waves of various ground objects. When the user analyzes the remote sensing image, it is necessary to accurately identify the content in the image, and the remote sensing image will generate some noise interference during the imaging process, resulting in problems such as low contrast and low resolution of the image, so that the picture in the image is not clear. Clear, indistinguishable content. [0003] In order to solve the above problems, it is necessary to perform image enhancement on remote sensing images. Image enhancement is a very important part of image preprocessing, which can enhance the clarity, visual effect and texture of images. In the process of image enhancement using the prior art, after the histogram ...
