Abstract
In various embodiments of the present invention, a number n of mutually interfering signals are denoised by selecting a discrete universal denoiser method that denoises n mutually interfering signals, tuning the discrete universal denoiser to denoise the n mutually interfering signals, and denoising the n mutually interfering signals by applying the tuned discrete universal denoiser to the n mutually interfering signals.
Claims21
A method for denoising n equals two or more mutually interfering signals, the method comprising:
- using a processor:
- selecting a discrete universal denoiser method that denoises n mutually interfering signals;
- tuning the discrete universal denoiser to denoise the n mutually interfering signals;
- and
- denoising the n mutually interfering signals by applying the tuned discrete universal denoiser to the n mutually interfering signals.
A system that includes a signal denoising component that denoises a set of n mutually interfering noisy signals obtained by a noise-introducing signal-acquisition process, the denoising component including:
- an embodiment of a selected discrete universal denoiser method that denoises noisy signals, tuned for denoising n mutually interfering noisy signals.
A method for denoising images of double-sided-document pages obtained by a noise-introducing image-acquisition process, the method comprising:
- using a processor:
- selecting a discrete universal denoiser method that denoises noisy images;
- tuning the discrete universal denoiser to denoise images of double-sided-document pages;
- and
- denoising images of double-sided-document pages by applying the tuned discrete universal denoiser to the images of double-sided-document pages.
A system that includes an image denoising component that denoises images of double-sided-document pages obtained by a noise-introducing image-acquisition process, the denoising component including:
- an embodiment of a selected discrete universal denoiser method that denoises noisy images, tuned for denoising double-sided-document pages.
A method for denoising images of double-sided-document pages obtained by a noise-introducing image-acquisition process, the method comprising:
- using a processor:
- selecting a discrete universal denoiser method that denoises noisy images;
- tuning the discrete universal denoiser to denoise pairs of images, each pair comprising an image of a front-side and an image of a back-side of a double-sided-document page;
- and
- pairwise denoising images of the front and back sides of double-sided-document pages by, for each double-sided-document page, aligning the image of the front-side and the image of the back-side of the double-sided-document page and applying the tuned discrete universal denoiser to a combined signal comprising the image of the front-side and the image of the back-side of the double-sided-document page.
A system that includes an image denoising component that pairwise denoises images of front and back sides of double-sided-document pages obtained by a noise-introducing image-acquisition process, the denoising component including:
- an embodiment of a selected discrete universal denoiser method that denoises combined signals, each combined signal comprising the front-side and back-side noisy images of a double-sided-document page, the selected discrete universal denoiser method tuned for denoising double-sided-document pages.
