Personal Photo Enhancement Using Example Images

Personal Photo Enhancement Using Example Images

2 weeks ago
We describe a framework for improving the quality of personal photos by using a person’s favorite photographs as examples. We observe that the majority of a person’s photographs include the faces of a photographer’s family and friends and often the errors in these photographs are the most disconcerting. We focus on correcting these types of […]
Automated Video Looping with Progressive Dynamism

Automated Video Looping with Progressive Dynamism

2 weeks ago
Given a short video we create a representation that captures a spectrum of looping videos with varying levels of dynamism, ranging from a static image to a highly animated loop. In such a progressively dynamic video, scene liveliness can be adjusted interactively using a slider control. Applications include background images and slideshows, where the desired […]
Interactively Stylizing Camera Motion

Interactively Stylizing Camera Motion

2 weeks ago
Movie directors and cinematographers impart style onto video using techniques that are learned through years of experience: camera movement, framing, color, lighting, etc. Without this experience and expensive equipment, it is very difficult to control stylistic aspects of a video. We introduce a novel approach for post-hoc editing of one specific aspect of cinematography – […]
Real-Time Hyperlapse Creation Via Optimal Frame Selection

Real-Time Hyperlapse Creation Via Optimal Frame Selection

2 weeks ago
Long videos can be played much faster than real-time by recording only one frame per second or by dropping all but one frame each second, i.e., by creating a timelapse. Unstable hand-held moving videos can be stabilized with a number of recently described methods. Unfortunately, creating a stabilized timelapse, or hyperlapse, cannot be achieved through […]

SubEdit: A Representation for Editing Measured Heterogeneous Subsurface Scattering

SubEdit: A Representation for Editing Measured Heterogeneous Subsurface Scattering

3 weeks ago
In this paper we present SubEdit, a representation for editing the BSSRDF of heterogeneous subsurface scattering acquired from real-world samples. Directly editing measured raw data is difficult due to the non-local impact of heterogeneous subsurface scattering on the appearance. Our SubEdit representation decouples these non-local effects into the product of two local scattering profiles defined […]
Printing Spatially-Varying Reflectance for Reproducing HDR Images

Printing Spatially-Varying Reflectance for Reproducing HDR Images

3 weeks ago
We present a solution for viewing high dynamic range (HDR) images with spatially-varying distributions of glossy materials printed on reflective media. Our method exploits the appearance variations of the glossy materials in the angular domain to display the input HDR image at different exposures. As viewers change the print orientation or lighting directions, the print […]
Lazy Solid Texture Synthesis

Lazy Solid Texture Synthesis

3 weeks ago
Existing solid texture synthesis algorithms generate a full volume of color content from a set of 2D example images. We introduce a new algorithm with the unique ability to restrict synthesis to a subset of the voxels, while enforcing spatial determinism. This is especially useful when texturing objects, since only a thick layer around the […]
Kernel Nyström Method for Light Transport

Kernel Nyström Method for Light Transport

3 weeks ago
We propose a kernel Nyström method for reconstructing the light transport matrix from a relatively small number of acquired images. Our work is based on the generalized Nyström method for low rank ¨ matrices. We introduce the light transport kernel and incorporate it into the Nyström method to exploit the nonlinear coherence of the light […]
Image‐based Material Weathering

Image‐based Material Weathering

3 weeks ago
The appearance manifold [WTL*06] is an efficient approach for modeling and editing time-variant appearance of materials from the BRDF data captured at single time instance. However, this method is difficult to apply in images in which weathering and shading variations are combined. In this paper, we present a technique for modeling and editing the weathering […]
Fabricating Spatially-Varying Subsurface Scattering

Fabricating Spatially-Varying Subsurface Scattering

3 weeks ago
Many real world surfaces exhibit translucent appearance due to subsurface scattering. Although various methods exist to measure, edit and render subsurface scattering effects, few solutions exist for manufacturing physical objects with desired translucent appearance. In this chapter, a complete solution is presented for fabricating a material volume with a desired surface BSSRDF. Layers are stacked […]
Global Illumination with Radiance Regression Functions

Global Illumination with Radiance Regression Functions

3 weeks ago
We present radiance regression functions for fast rendering of global illumination in scenes with dynamic local light sources. A radiance regression function (RRF) represents a non-linear mapping from local and contextual attributes of surface points, such as position, viewing direction, and lighting condition, to their indirect illumination values. The RRF is obtained from precomputed shading […]
