Mathematical framework for perception-driven parameter choice in image denoising
Saara Isoranta, Emilia L. K. Blåsten, Lílian Ferreira de Freitas +3
We approach image denoising from a perception-driven perspective: how can we select the parameters that are best suited for human visual perception? We combine research methods in…
Recomposed realities: animating still images via patch clustering and randomness
Markus Juvonen, Samuli Siltanen
We present a patch-based image reconstruction and animation method that uses existing image data to bring still images to life through motion. Image patches from curated datasets a…
Dual-grid parameter choice method with application to image deblurring
Markus Juvonen, Bjørn Jensen, Ilmari Pohjola +2
Variational regularization of ill-posed inverse problems is based on minimizing the sum of a data fidelity term and a regularization term. The balance between them is tuned using a…
Helsinki Speech Challenge 2024
Martin Ludvigsen, Elli Karvonen, Markus Juvonen +1
The Helsinki Speech Challenge 2024 (HSC2024) invites researchers to enhance and deconvolve speech audio recordings. We recorded a dataset that challenges participants to apply spee…
Helsinki Deblur Challenge 2021: description of photographic data
Markus Juvonen, Samuli Siltanen, Fernando Silva de Moura
The photographic dataset collected for the Helsinki Deblur Challenge 2021 (HDC2021) contains pairs of images taken by two identical cameras of the same target but with different co…
