Electrophysiological and fMRI-based investigations of the ventral temporal cortex of primates provide strong support for regional specialization for the processing of faces. These responses are most frequently found in or near the fusiform gyrus, but there is substantial variability in their anatomical location and response properties. An outstanding question is the extent to which ventral temp...

Application of digital signal processing to audio is often limited by available converter technology and recorder datawidth to processes with controlled dynamic range. In digital mixing consoles some analogue gain control is normally required to achieve adequate performance for the input channel ADCs and digital multi-track recorders. This paper examines such dynamic range bottlenecks and deriv...

F ield programmable gate array (FPGA) components are widely used nowdays to implement various algorithms, such as digital filtering, in real time. The emergence of dynamically reconfigurable FPGAs made it possible to reduce the number of necessary resources to carry out an image-processing task (tasks chain). In this article, an image-processing application, image rotation, that exploits the FP...

The high dynamic range of illumination may cause serious distortions and problems in the view and further processing of digital images. In this paper a new fuzzy based tone reproduction pre-processing algorithm is introduced which may help in developing the hardly or non viewable features and content of the images making easier the further processing.

This paper discusses a dynamic method of edge detection which works from a sequence of frames. Most edge detection algorithms process image information statically, regardless of whether the application is static i.e. whether the input is a singular, unique image or a dynamic sequence of frames used for tracking or optic flow extraction. As many applications are dynamic, such as robotics, autono...

Louis Perrochon ABSTRACT Complex Event Processing (CEP) is an upcoming technology to test, analyze verify, monitor or just study complex programs or systems. CEP is particularly well suited for complexity arising from asynchronous, non-deterministic execution in distributed systems. Application domains include: software engineering, manufacturing, network management, etc. We present the archite...

Due to dynamic range compression and contrast enhancement realized simultaneously in traditional image enhancement algorithm based on frequency domain, which cause the low contrast degree, an improved image enhancement algorithm based on fuzzy filter is proposed in this paper. According to subjective feeling of the human visual system to light luminance, the image is processed with the global b...

Analyzing large and distributed image datasets is a crucial step in understanding the structural and functional characteristics of biological systems. In this paper, we present the design and implementation of a toolkit that allows rapid and efficient development of biomedical image analysis applications in a distributed environment. This toolkit employs the Insight Segmentation and Registratio...

A directional hearing aid adapter was designed and implemented using Dynamic Translinear (DTL) circuit techniques. The signal-processing core was optimized to yield minimum current consumption for the specified dynamic range. In this paper the design and implementation of the core is presented. It consumes a current of 40 μA at a supply voltage of down to 1.0 V having a total integrated capacit...

We investigate the potential of strategic ship routing through dynamic currents derived from satellite altimetry by simulating current patterns in a dynamic Gulf Stream region to reflect present and improved current estimation capabilities, using dynamic programming to determine approximately 3-day routes through the current patterns, and estimating relative fuel savings that would be obtained ...
