A comparative study of image retargeting
TLDR
This work creates a benchmark of images and conducts a large scale user study to compare a representative number of state-of-the-art retargeting methods, and presents analysis of the users' responses, where it is found that humans in general agree on the evaluation of the results and show that some retargeted methods are consistently more favorable than others.

Scattering
TLDR
This course addresses the challenges that arise with light scattering in computer graphics and computer vision, including appearance modeling, underwater imagery, vision in bad weather, and measurement techniques. Expand
Saliency in VR: How Do People Explore Virtual Environments?
TLDR
This work captures and analyzes gaze and head orientation data of 169 users exploring stereoscopic, static omni-directional panoramas, for a total of 1980 head and gaze trajectories for three different viewing conditions, which leads to several important insights, such as the existence of a particular fixation bias.

Evaluation of reverse tone mapping through varying exposure conditions
TLDR
It is shown that current rTMO approaches fall short when the input image is not exposed properly, and proposed a method to automatically set a suitable gamma value for each image, based on the image key and empirical data, which enhances visible details without causing artifacts in incorrectly-exposed regions. Expand
Intrinsic Images by Clustering
TLDR
A novel algorithm that requires no user strokes and works on a single image is presented, based on simple assumptions about its reflectance and luminance, which builds a linear system describing the connections and relations between them. Expand
High-quality hyperspectral reconstruction using a spectral prior
TLDR
A novel hyperspectral image reconstruction algorithm, which overcomes the long-standing tradeoff between spectral accuracy and spatial resolution in existing compressive imaging approaches and introduces a novel optimization method, which jointly regularizes the fidelity of the learned nonlinear spectral representations and the sparsity of gradients in the spatial domain. Expand
A similarity measure for illustration style
TLDR
This paper presents a method for measuring the similarity in style between two pieces of vector art, independent of content, and demonstrates an application that allows users to create stylistically-coherent clip art mash-ups. Expand
DeepToF: off-the-shelf real-time correction of multipath interference in time-of-flight imaging
TLDR
A new technique is proposed that corrects errors in depth caused by MPI that requires no camera modifications, and corrects depth in just 10 milliseconds per frame, and is demonstrated and validated on both synthetic and real complex scenarios. Expand
Femto-photography
TLDR
This work introduces reconstruction methods that allow us to visualize the propagation of femtosecond light pulses through macroscopic scenes, and introduces the notion of time-unwarping between the camera's and the world's space-time coordinate systems to take into account effects associated with the finite speed of light. Expand
Dynamic range expansion based on image statistics
TLDR
This work improves an existing, automatic, global reverse tone mapping operator based on a gamma expansion by providing a new way for automatic parameter calculation from the image statistics, and shows that this method yields better results across the whole range of exposures. Expand
