We present two detectors which allow multiuser detection without a side channel in a dynamic CDMA system where users are constantly leaving and entering the system. These detectors, the Maximum Likelihood (ML) and Generalized Maximum Likelihood (GML) detectors, optimally detect a new user given only the chip rate and the spreading factor of the new user. Each of these detectors produces maximum...

Over the years a number of powerful people detectors have been proposed. While it is standard to test complete detectors on publicly available datasets, it is often unclear how the di erent components (e.g. features and classi ers) of the respective detectors compare. Therefore, this paper contributes a systematic comparison of the most prominent and successful people detectors. Based on this e...

In this paper, we describe a generic methodology for evaluating the labeling performance of feature detectors. We describe a method for generating a test set and apply the methodology to the performance assessment of three well-known corner detectors: the Kitchen-Rosenfeld, Paler et al., and Harris-Stephens corner detectors. The labeling deficiencies of each of these detectors is related to the...

We present smooth formulations of common vortex detectors that allow a seamless integration into the concept of interactive visual analysis of flow simulation data. We express the originally binary feature detectors as fuzzy-sets that can be combined using the linking and brushing concepts of interactive visual analysis. Both interaction and visualization gain from having multiple detectors con...

A systematic approach for the derivation of UWB detectors cannot be found in the literature. The detectors published up to now have been developed by inspection, using a heuristic approach. However, that solution prevents the optimization of UWB detector performance. A new approach is proposed here for the derivation of optimum waveform detectors that is valid for each type of carriers. To illu...

Parity is a key observable in nuclear spectroscopy. Linear polarization measurements of γ-rays are a probe to access the parities of energy levels. Utilizing the segmentation of detectors in the Segmented Germanium Array (SeGA) at the NSCL and analyzing the positions of interaction therein allows the detectors to be used as Compton polarimeters. Unlike other segmented detectors, SeGA detectors ...

A promising class of nonlinear multiuser detectors is introduced for CDMA systems. These “iterated-decision” multiuser detectors use optimized multipass algorithms to successively cancel multipleaccess interference (MAI) from received data and generate symbol decisions whose reliability increases monotonically with each iteration. They significantly outperform decorrelating detectors and linear...

This report describes the first stage in solving the structure from motion problem, which is to detect feature points and track them from frame to frame. A number of detectors from the literature, as well as some specially developed detectors, are assessed using a fly-over sequence of Parafield control tower. It is found by this measure that the Harris detector is the best of the conventional d...
