Problems solved by technology

However, the shortcomings of this method are: this method does not take into account the information of the low-resolution hyperspectral image, and there is no connection between the spectral dictionary and the width-height dictionary, so that the hyperspectral image obtained by this method cannot be very accurate. The information of the image dimension is well preserved, and this method needs continuous it...

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] refer to figure 1 , The specific implementation steps of the present invention are as follows.

[0032] Step 1. Establish training set and test set:.

[0033] Create a training set for training the model and a test set for testing the model, both of which are empty.

[0034] Step 2. Input spectral image.

[0035] A single low-resolution hyperspectral image and a high-resolution multispectral image in the same scene corresponding to the hyperspectral image are input into the training set, and the spectral transformation matrix between the two is input into the training set.

[0036] The low-resolution hyperspectral image refers to an image with high spectral dimension resolution and low image dimension resolution.

[0037] The high-resolution multispectral image refers to an image with a low spectral dimension resolution and a high image dimension resolution....

Abstract

The present invention discloses a hyperspectral and multispectral image rapid fusion method. The method comprises the implementation steps of: (1) establishing a training set and a test set; (2) inputting a spectrum image; (3) establishing a probability generation model; (4) training a probability generation model; and (5) obtaining a fusion spectrum image. The hyperspectral and multispectral image rapid fusion method overcomes the problems that a representational capacity is weak, the model is not stable and the operation time is long in the prior art, generated hyperspectral image with highresolution comprises more information, a space transfer matrix without priori conditions is employed to allow the model to be more stable and allow the fusion speed to be faster, and therefore the hyperspectral and multispectral image rapid fusion method is a high-speed and efficient hyperspectral image fusion processing method.

Description

technical field [0001] The invention belongs to the technical field of image processing, and further relates to a fast fusion method of hyperspectral and multispectral images in the technical field of image fusion. The invention can be used for low-resolution hyperspectral images and high-resolution multi-spectral images, and uses image fusion technology to generate high-resolution hyperspectral images. Background technique [0002] The hyperspectral image integrates image information and spectral information. The image information can reflect the external quality characteristics such as the size, shape, and defects of the sample. Due to the difference in the absorption of the spectrum by different components, the image at a specific wavelength will be sensitive to a defect. These characteristics determine the unique advantages of hyperspectral images in detection. Compared with multispectral images, hyperspectral images not only have a great improvement in information rich...
