Abstract

The invention discloses an image processing method and device, relates to the field of remote sensing images, and can solve the problem that the definition of a remote sensing image cannot be effectively enhanced in the prior art. The image processing method comprises the following steps: carrying out passivation fuzzy processing on a first image; performing various special-shaped diffusion on thefirst image after the passivation fuzzy processing to enable the noise of the first image in each direction to be smooth; copying the first image to obtain a second image; performing two-dimensionaldiscrete wavelet transform on the processed first image to obtain a first high-frequency sub-image and a first low-frequency sub-image, and performing two-dimensional discrete wavelet transform on theprocessed second image to obtain a second high-frequency sub-image and a second low-frequency sub-image; and performing image fusion on the first high-frequency sub-image, the first low-frequency sub-image, the second high-frequency sub-image and the second low-frequency sub-image according to the set high-frequency coefficient and low-frequency coefficient of the fused image to obtain a fused image. The method can be widely applied to the scene of processing the remote sensing image.

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 size of electromagnetic waves of various ground features. When users analyze remote sensing images, they need to accurately identify the content in the images, and the remote sensing images will generate some noise interference during the imaging process, resulting in low contrast and low resolution of the image, making the picture in the image inaccurate. Clear, difficult to distinguish 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 the image. However, in the image enhancement process using the existing technology, the average value of the imag...
