Abstract
A method for reconstructing a hyperspectral image and a system therefor are provided. The method includes obtaining a dispersion model for dispersion created by a prism included in a camera, the prism including no coded aperture, and reconstructing a hyperspectral image corresponding to a captured image based on the dispersion model.
Claims20
A method for reconstructing a hyperspectral image, the method comprising:
- obtaining a dispersion model for dispersion created by a prism included in a camera, the prism including no coded aperture;
- and
- reconstructing a hyperspectral image corresponding to a captured image based on the dispersion model.
A method for reconstructing a hyperspectral image, the method comprising:
- aligning an input dispersed captured image through a prism included in a camera, the prism including no coded aperture, and obtaining edge information without dispersion;
- estimating spectral information based on the obtained edge information and a dispersion model for dispersion created by the prism;
- and
- reconstructing a hyperspectral image corresponding to the captured image based on the estimated spectral information.
A camera device, comprising:
- a first obtaining unit configured to obtain a dispersion model for dispersion created by a prism included in a camera, the prism including no coded aperture;
- and
- a reconstruction unit configured to reconstruct a hyperspectral image corresponding to a captured image based on the dispersion model.
A system for reconstructing a hyperspectral image, the system comprising:
- a prism included in a camera;
- and
- a camera device,
- wherein the camera device is configured to:
- obtain a dispersion model for dispersion created by the prism including no coded aperture;
- and
- reconstruct a hyperspectral image corresponding to a captured image based on the dispersion model.
