A universal statistical model for texture images in the context of an overcomplete complex wavelet transform is presented, demonstrating the necessity of subgroups of the parameter set by showing examples of texture synthesis that fail when those parameters are removed from the set.
Abstract
We present a universal statistical model for texture images in the context of an overcomplete complex wavelet transform. The model is parameterized by a set of statistics computed on pairs of coefficients corresponding to basis functions at adjacent spatial locations, orientations, and scales. We develop an efficient algorithm for synthesizing random images subject to these constraints, by iteratively projecting onto the set of images satisfying each constraint, and we use this to test the perceptual validity of the model. In particular, we demonstrate the necessity of subgroups of the parameter set by showing examples of texture synthesis that fail when those parameters are removed from the set. We also demonstrate the power of our model by successfully synthesizing examples drawn from a diverse collection of artificial and natural textures.

System and method for encoding and decoding using texture replacement

TL;DR: In this article, the authors proposed a method to synthesize texture based on the received texture information, which is then decoded to obtain a decoded image, and then map the synthesized texture onto the decoded images.

Depth-image-based rendering with spatial and temporal texture synthesis for 3DTV

TL;DR: A depth-image-based rendering (DIBR) method with spatial and temporal texture synthesis is presented, which combines the temporally stationary scene information extracted from the input video and spatial texture in the current frame to fill the disoccluded areas in the virtual views.

Locally adaptive multiscale contrast optimization

TL;DR: A method for automatically and adaptively boosting the visibility of local features in an image using a scale-invariant spectral model and a spatial mask is applied in the pixel domain to ensure that the enhancements are applied only in the vicinity of image features.

Auto Localization and Segmentation of Occluded Vessels in Robot-Assisted Partial Nephrectomy

TL;DR: This work proposes an automatic method to localize and label occluded vasculature and assigns segmentation labels based on identifying responses of regions exhibiting temporal local phase changes matching the heart rate frequency from phase-based video magnification.

Learning to Warp for Style Transfer

TL;DR: In this article, a neural network is proposed to learn a mapping from a 4D array of inter-feature distances to a non-parametric 2D warp field, which can be used with a single style exemplar.

A theory for multiresolution signal decomposition: the wavelet representation

TL;DR: In this paper, it is shown that the difference of information between the approximation of a signal at the resolutions 2/sup j+1/ and 2 /sup j/ (where j is an integer) can be extracted by decomposing this signal on a wavelet orthonormal basis of L/sup 2/(R/sup n/), the vector space of measurable, square-integrable n-dimensional functions.

Stochastic Relaxation, Gibbs Distributions, and the Bayesian Restoration of Images

TL;DR: The analogy between images and statistical mechanics systems is made and the analogous operation under the posterior distribution yields the maximum a posteriori (MAP) estimate of the image given the degraded observations, creating a highly parallel ``relaxation'' algorithm for MAP estimation.

Information Theory and Statistical Mechanics. II

TL;DR: In this article, the authors consider statistical mechanics as a form of statistical inference rather than as a physical theory, and show that the usual computational rules, starting with the determination of the partition function, are an immediate consequence of the maximum-entropy principle.

Orthonormal bases of compactly supported wavelets

TL;DR: This work construct orthonormal bases of compactly supported wavelets, with arbitrarily high regularity, by reviewing the concept of multiresolution analysis as well as several algorithms in vision decomposition and reconstruction.

Relations between the statistics of natural images and the response properties of cortical cells.

TL;DR: The results obtained with six natural images suggest that the orientation and the spatial-frequency tuning of mammalian simple cells are well suited for coding the information in such images if the goal of the code is to convert higher-order redundancy into first- order redundancy.
