Real-Time Human Pose Recognition in Parts from Single Depth Images
We propose a new method to quickly and accurately predict human pose — the 3-D positions of body joints — from a single depth image, without depending on information...

Technical Perspective: Visualization, Understanding, and Design
Photographs capture the moment; paintings convey perception, impression, and feeling; illustrations tell stories. Computer graphics aims to enrich all these artistic...

Illustrating How Mechanical Assemblies Work
How-things-work visualizations use a variety of visual techniques to depict the operation of complex mechanical assemblies. We present an automated approach for...

Technical Perspective: Natural Algorithms in a Networked World
How do birds flock and fish school? How do individuals in a social network reach agreement, even though they are often only influenced by other like-minded individuals...

Natural Algorithms and Influence Systems
Algorithms lay the grounds for numerical simulations and, crucially, provide a powerful framework for their analysis. The new area of natural algorithms may reprise...

An Introduction to Data Representation Synthesis
We consider the problem of specifying combinations of data structures with complex sharing in a manner that is declarative and results in provably correct code.

Technical Perspective: The Realities of Home Broadband
Buying residential broadband services seems relatively simple: pick among a small number of plans, and then compare similar plans by price. Unfortunately, reality...

Measuring Home Broadband Performance
We present the results from the first study of Internet access link performance measured directly from home routers. Our findings provide a snapshot of access network...

Technical Perspective: Open Platforms For Computational Photography
A fundamental impediment to the widespread development and deployment of in-camera algorithms is the lack of a clean open architecture for controlling camera...

The Frankencamera: An Experimental Platform For Computational Photography
Progress in computational photography has been hampered by the lack of a portable, programmable camera with sufficient image quality and computing power. To address...

Technical Perspective: A High-Dimensional Surprise
High-dimensional space is a counterintuitive place, where natural geometric intuitions from the familiar three-dimensional world may lead us badly astray.

Spherical Cubes: Optimal Foams from Computational Hardness Amplification
Foam problems are about how to best partition space into bubbles of minimal surface area. We investigate the case where one unit-volume bubble is required to tile...

Technical Perspective: SQL on an Encrypted Database
There is some risk in trusting the cloud providers with sensitive data. Why not encrypt the data stored in cloud services?

CryptDB: Processing Queries on an Encrypted Database
An ideal solution to satisfying the dual goals of protecting data confidentiality and running computations is to enable a server to compute over encrypted data,...
