    For most people, three dimensional (3-D) is just another example of "movie magic." Yet for the researchers developing and refining the 3-D technologies behind today's big-screen block busters, as well as for applications in a variety of other fields, the work is very real and decidedly non-magical. Beyond entertainment, 3-D technology is finding a place in such diverse fields as engineering, chemi... View full abstract»

    Over the past decade, large-scale camera networks have become increasingly prevalent in a wide range of applications, such as security and surveillance, disaster response, and environmental modeling. In many applications, bandwidth constraints, security concerns, and difficulty in storing and analyzing large amounts of data centrally at a single location necessitate the development of distributed ...

    The development of distributed computer vision algorithms promises to significantly advance the state of the art in computer vision systems by improving their efficiency and scalability (through the efficient integration of local information with global optimality guarantees) as well as their robustness to outliers and node failures (because of the use of redundant information). However, in order ... View full abstract»

    We discussed emerging multicamera tracking algorithms that find their roots in signal processing, wireless sensor networks, and computer vision. Based on how cameras share estimates and fuse information, we classified these trackers as distributed, decentralized, and centralized algorithms. We also highlighted the challenges to be addressed in the design of decentralized and distributed tracking a... View full abstract»

    Lattice reduction is a powerful concept for solving diverse problems involving point lattices. Signal processing applications where lattice reduction has been successfully used include global positioning system (GPS), frequency estimation, color space estimation in JPEG pictures, and particularly data detection and precoding in wireless communication systems. In this article, we first provide some... View full abstract»

    As of today, orthogonal frequency division multiplexing (OFDM) has been the dominant technology for broadband multicarrier communications. However, in certain applications such as cognitive radios and uplink of multiuser multicarrier systems, where a subset of subcarriers is allocated to each user, OFDM may be an undesirable solution. In this article, we address the shortcomings of OFDM in these a... View full abstract»

    Remotely sensed hyperspectral imaging instruments are capable of collecting hundreds of images corresponding to different wave length channels for the same area on the surface of the Earth. For instance, NASA is continuously gathering high dimensional image data with instruments such as the Jet Propulsion Laboratory's Airborne Visible-Infrared Imaging Spectrometer (AVIRIS). This advanced sensor fo... View full abstract»

    We connect to the two recent IEEE Signal Processing Magazine special issues on digital signal processing (DSP) on multicore processors (November 2009 and March 2010) and address an issue that was not addressed in the articles there, which we believe has important consequences for DSP algorithm design in the future. The basic observation that we start out with is that in DSP algorithm design, there... View full abstract»

  • The Gaussian Data Assumption Leads to the Largest Cramér-Rao Bound [Lecture Notes]

    The Gaussian data assumption is sometimes criticized as being unrealistic in certain applications. While this is a valid criticism, it is also true that the Gaussian assumption is a natural choice when nothing is known about the exact data distribution. The argument typically used to motivate this choice relies on the fact that the Gaussian distribution leads to the largest Cramer-Rao bound (CRB) ... View full abstract»

    Sampling rate conversion (SRC) is usually performed in the time domain by using the operations of up-sampling, filtering, and down-sampling. However, it is also possible to perform the SRC in the frequency domain by formulating the desired spectrum from the spectrum of an input signal. This article shows how to perform SRC for both integer and fractional-rate conversion by manipulating the discret... View full abstract»

    A t the recent ACM Multimedia conference in Florence, Ramesh Jain boldly and succinctly stated, "Content without context is meaningless." He presented a paper on the topic at the conference's Brave New Ideas session and challenged multimedia researchers to "stop ignoring the elephant in the room" (context) and to recognize that by reducing problems to being entirely content focused, they are doing...
