Problems solved by technology

The disadvantage is that this method treats all bands equally, and adopts the same processing method and steps, which will cause spectral distortion of those bands (such as the blue band) that are weakly correlated with the panchromatic band, so that when combined with other bands for color synthesis , resulting in color distortion

Embodiment Construction

[0028] The purpose of the present invention is to overcome the deficiencies of the prior art, increase the judgment of the correlation between each band and the panchromatic band, and adopt different high-frequency modulation strategies according to the difference in correlation to reduce the spectral distortion of the weakly correlated band. The present invention provides a method for generating high-resolution multi-spectral images through high-frequency modulation, which belongs to the method for generating high-resolution multi-spectral images by fusion of images such as Akonos satellites, and also includes resampling low-resolution multi-spectral images, Obtain super-pixel multi-spectral images; perform multiple linear regression on high-resolution panchromatic images and super-pixel multi-spectral images to synthesize and simulate low-resolution panchromatic images; high-frequency modulation generates three parts of each band of high-resolution multi-spectral images. Howe...

Abstract

This invention provides one high frequency modulation spectrum image with high resolution generation method, which comprises sampling resolution rate multi-spectrum image to get super image pixel; exerting multiple linear regressions of the full-color image and super pixel spectrum image to integrate artificial full-color image with low resolution; high frequency modulation to generate spectrum image. The invention is characterized by the following: generating optical spectrum image part in the high frequency modulation; judging whether relationship between the spectrum pixels images each waveband and original full-color image and adopting different frequency modulation type.

Description

technical field [0001] The invention relates to image processing technology, which belongs to the field of remote sensing image processing data fusion technology, in particular to a technology for generating high-resolution multi-spectral images by fusing low-resolution multi-spectral bands and high-resolution panchromatic bands of the same sensor of optical remote sensing satellites, especially a technology A method for high-frequency modulation to generate high-resolution multispectral images. Background technique [0002] Many optical remote sensing satellite systems simultaneously provide multispectral images with low spatial resolution and panchromatic images with high spatial resolution. A 4-meter multispectral image containing blue, green, red, and near-infrared bands. In order to optimize the use of information, especially the use of high-resolution information in the panchromatic band, many image fusion techniques strive to combine the high spatial resolution infor...
