Edge-preserving multiscale image decomposition based on local extrema
TL;DR: In this paper, the local extrema of the input image is used to extract information about oscillations, a key property that distinguishes textures from individual edges, and an algorithm for decomposing images into multiple scales of superposed oscillations is developed.
Edge-preserving Multiscale Image Decomposition based on Local Extrema
TL;DR: A new model for detail is proposed that inherently captures oscillations, a key property that distinguishes textures from individual edges, and an algorithm for decomposing images into multiple scales of superposed oscillations is developed.
Journal ArticleDOI
Fourier depth of field
TL;DR: An analysis of focusing and depth-of-field in the frequency domain is introduced, allowing a practical characterization of a light field's frequency content both for image and aperture sampling.
Journal ArticleDOI
5D Covariance tracing for efficient defocus and motion blur
TL;DR: A new frequency analysis of the 5D temporal light-field is developed, and it is shown that first-order motion can be handled through simple changes of coordinates in 5D, and a compact representation of the spectrum using the covariance matrix and Gaussian approximations is introduced.
Proceedings ArticleDOI
Towards Moment Imagery: Automatic Cinemagraphs
TL;DR: In this paper, the authors present a tool combining video motion stabilisation, segmentation, interactive motion selection, motion loop detection and selection, and cinema graph rendering, which can capture the dynamics of one particular region in an image for dramatic effect and provide the creator with control over what part of a moment to capture.
