1 results about "Hyperspectral image compression" patented technology

The application provides a hyperspectral image compression reconstruction method and system guided by a spectral gradient, the method comprising collecting a hyperspectral image and performing preprocessing on the hyperspectral image to construct a hyperspectral image dataset; constructing an end-to-end spectral gradient guided network, the spectral gradient guided network comprising an encoder and a decoder; the spectral gradient Transformer module is arranged in the encoder and the decoder; the hyperspectral image dataset is used to perform end-to-end training on the spectral gradient guided network; the hyperspectral image to be compressed is input into the trained spectral gradient guided network, the encoder is used to encode the hyperspectral image to be compressed to obtain compressed encoding data; the decoder is used to decode the compressed encoding data to obtain a reconstructed hyperspectral image. The application can realize efficient compression and high-fidelity reconstruction of urban scene hyperspectral images, and provides reliable technical support for engineering landing of hyperspectral imaging technology in the field of urban intelligent driving.
