CG2Real: Improving the Realism of Computer Generated Images using a Large Collection of Photographs 

Pfister, Hanspeter; Freeman, William T.; Avidan, Shai; Dale, Kevin; Johnson, Micah K.; e.a. (2009-07-15)
Computer Graphics (CG) has achieved a high level of realism, producing strikingly vivid images. This realism, however, comes at the cost of long and often expensive manual modeling, and most often humans can still distinguish ...

Contextual models for object detection using boosted random fields 

Torralba, Antonio; Murphy, Kevin P.; Freeman, William T. (2004-06-25)
We seek to both detect and segment objects in images. To exploit both local image data as well as contextual information, we introduce Boosted Random Fields (BRFs), which uses Boosting to learn the graph structure and local ...

Sharing visual features for multiclass and multiview object detection 

Torralba, Antonio; Murphy, Kevin P.; Freeman, William T. (2004-04-14)
We consider the problem of detecting a large number of different classes of objects in cluttered scenes. Traditional approaches require applying a battery of different classifiers to the image, at multiple locations and ...

Shape-Time Photography 

Freeman, William T.; Zhang, Hao (2002-01-10)
We introduce a new method to describe, in a single image, changes in shape over time. We acquire both range and image information with a stationary stereo camera. From the pictures taken, we display a composite image ...

Properties and Applications of Shape Recipes 

Torralba, Antonio; Freeman, William T. (2002-12-01)
In low-level vision, the representation of scene properties such as shape, albedo, etc., are very high dimensional as they have to describe complicated structures. The approach proposed here is to let the image itself ...

Random Lens Imaging 

Fergus, Rob; Torralba, Antonio; Freeman, William T. (2006-09-02)
We call a random lens one for which the function relating the input light ray to the output sensor location is pseudo-random. Imaging systems with random lensescan expand the space of possible camera designs, allowing new ...

Tiny images 

Torralba, Antonio; Fergus, Rob; Freeman, William T. (2007-04-23)
The human visual system is remarkably tolerant to degradations in image resolution: in a scene recognition task, human performance is similar whether $32 \times 32$ color images or multi-mega pixel images are used. With ...

4D Frequency Analysis of Computational Cameras for Depth of Field Extension 

Levin, Anat; Hasinoff, Samuel W.; Freeman, William T.; Green, Paul; Durand, Fredo (2009-05-08)
Depth of field (DOF), the range of scene depths that appear sharp in a photograph, poses a fundamental tradeoff in photography---wide apertures are important to reduce imaging noise, but they also increase defocus blur. ...
