Constrained Texture Restoration
Amethod is proposed for filling in missing areas of degraded images through explicit structure reconstruction, followed by texture synthesis. The structure being reconstructed represents meaningful edges from the image, which are traced inside the artefact. The structure reconstruction step relies on different properties of the edges touching the artefact and of the areas between them, in order...
متن کاملAudio restoration by constrained audio texture synthesis
Audio texture, a new audio medium, is used to synthesize long audio stream according to a given short example audio clip. In this paper, we extend this idea to audio texture restoration, or constrained audio texture synthesis for restoring those missing parts in an audio clip. It is useful in many applications such as audio restoration and audio reconstruction. It can also be used in error conc...
متن کاملConstrained Image Restoration with
A Bayesian image processing model is proposed based on a Markovian Multinomial Prior. The technique has application in texture segmentation where its introduction of spatial context can improve segmentation accuracy by 60%. Other applications include general image restoration where 18 dB SNR improvement is possible. In addition, the computational complexity of the system is low, making it ideal...
متن کاملConstrained Sparse Texture Synthesis
This paper presents a novel texture synthesis algorithm that performs a sparse expansion of the patches of the image in a dictionary learned from an input exemplar. The synthesized texture is computed through the minimization of a non-convex energy that takes into account several constraints. Our first contribution is the computation of a sparse expansion of the patches imposing that the dictio...
متن کاملWavelet-Constrained Image Restoration
Image restoration problems can naturally be cast as constrained convex programming problems in which the constraints arise from a priori information and the observation of signals physically related to the image to be recovered. In this paper, the focus is placed on the construction of constraints based on wavelet representations. Using a mix of statistical and convex-analytical tools, we propo...
