1 results about "Hyperspectral image fusion" patented technology

This invention proposes a hyperspectral image fusion and reconstruction method based on cross-modal interaction and difference perception. The steps are as follows: acquiring training and testing sample sets; constructing a reconstruction network model based on cross-modal interaction and difference perception; iteratively training the reconstruction network model; and obtaining the reconstruction results of the hyperspectral image. The residual module of this invention utilizes multiple cross-modal interaction modules (CIMB) to perform cross-modal collaborative interaction on the spectral-spatial feature maps of LR-HSI and HR-MSI, enabling the mining of interaction features and contextual features between the two modalities. The difference perception fusion module (DPFM) performs difference perception and fusion on the cross-modal interaction features output by CIMB, effectively enhancing key details while mitigating distortion caused by differences between the two modal features, thus significantly improving reconstruction accuracy.
