Spatially adaptive statistical modeling of wavelet image coefficients and its application to denoising
TLDR
This paper deals with the application to denoising of a very simple but effective "local" spatially adaptive statistical model for the wavelet image representation that was previously introduced successfully in a compression context. Expand

Position calibration of microphones and loudspeakers in distributed computing platforms
TLDR
We present a novel algorithm to automatically determine the relative three-dimensional (3-D) positions of audio sensors and actuators in an ad hoc distributed network of heterogeneous general purpose computing platforms such as laptops, PDAs, and tablets. Expand

To search or to label?: predicting the performance of search-based automatic image classifiers
TLDR
In this work we explore the trade-offs in acquiring training data for image classification models through automated web search as opposed to human annotation. Expand

Joint source channel matching for a wireless communications link
TLDR
We develop a general approach for joint source channel matching based on a parametric distortion model that incorporates the flexibility and constraints of both the source and the channel. Expand

On the importance of exact synchronization for distributed audio signal processing
TLDR
We propose a new paradigm for implementations of audio array processing algorithms on a network of distributed general-purpose computers (GPC) with onboard sensors. Expand

Image transmission using arithmetic coding based continuous error detection
TLDR
We propose a new "continuous" error detection scheme using arithmetic coding that provides a novel tradeoff between the amount of added redundancy and the time needed to detect an error once it occurs. Expand
