Abstract

The invention refers to an image merging method based on filter group, making filter group decomposition on high-resolution panchromatic image and multispectral image, respectively, to obtain sub-images of many frequency bands, adopting low-frequency part of multispectral image to replace that of high-resolution panchromatic image to merge different resolution remote sensing images, and finally reconfigures the filter group to obtain the merged image.

Description

Technical field: [0001] The invention relates to an image fusion method based on a filter group, which is used for fusing panchromatic images with high spatial resolution and multispectral images with low spatial resolution. It is widely used in various civilian or military remote sensing information processing systems, digital city space information systems and other fields. Background technique: [0002] With the rapid development of imaging sensor technology, remote sensing image processing has developed from a single-platform, single-sensor processing method to a multi-platform, multi-sensor multi-image processing method. Due to the use of different imaging sensors, different remote sensing data have different spatial and spectral resolutions. For multispectral sensors, it can obtain multispectral images with high spectral resolution and low spatial resolution; for panchromatic sensors, remote sensing images with high spatial resolution can be obtained. Using image fus...
