High dynamic range digital audio is the next frontier in audio reproduction. Achieving it means removing the many errors that typically compromise accuracy and thus the sense of realism that enthusiasts desire. High dynamic range starts with the power supply, then the digital-to-analog conversion, and continues right through to the speakers’ output. If the DAC is flawed then nothing that follow...

Spectral filter arrays imaging exhibits a strong similarity with color filter arrays. This permits us to embed this technology in practical vision systems with little adaptation of the existing solutions. In this communication, we define an imaging pipeline that permits high dynamic range (HDR)-spectral imaging, which is extended from color filter arrays. We propose an implementation of this pi...

This paper presents a novel framework to extend the dynamic range of images called Unbounded High Dynamic Range (UHDR) photography with a modulo camera. A modulo camera could theoretically take unbounded radiance levels by keeping only the least significant bits. We show that with limited bit depth, very high radiance levels can be recovered from a single modulus image with our newly proposed u...

We describe the design and implementation of a high dynamic range (HDR) imaging system capable of capturing RGB color images with a dynamic range of 10,000,000 : 1 at 25 frames per second. We use a highly programmable camera unit with high throughput A/D conversion, data processing and data output. HDR acquisition is performed by multiple exposures in a continuous rolling shutter progression ov...

In this paper, we present a comprehensive tone reproduction curve based operator for the fast visualization of high dynamic range images. Image reproduction is a highly subjective process and different users will have very different preferences even for the same image. Therefore, a really useful tone-mapping tool for high dynamic range images should be fast and interactive, with which users can...

It is possible to interpret the shape of buildings based on synthetic aperture radar (SAR) images acquired using airborne SAR systems. However, the pixel values of SAR images have high dynamic range intensity, and SAR images are not displayable without dynamic range intensity compression. We therefore have developed a dynamic range intensity compression method suitable for SAR image features. U...

A Dynamic Data Driven Application Systems (DDDAS) approach is developed for evaluation of fluid-thermal systems wherein a complete specification of the boundary conditions is not known a priori and experimental diagnostics are restricted to a limited region of the flowfield. The methodology is applied to the configuration of a heated jet injected into a laminar boundary layer where the jet temp...

This work present several advances in the understanding of dynamic data structures in the bit-probe model: • We improve the lower bound record for dynamic language membership problems to Ω(( lg n lg lg n ) ). Surpassing Ω(lg n) was listed as the first open problem in a survey by Miltersen. • We prove a bound of Ω( lg n lg lg lg n ) for maintaining partial sums in Z/2Z. Previously, the known bou...

This paper describes the bubble drum set, along with several polyrhythm games and interactive music activities that have been developed to show its potential for use as an input controller. The bubble drum set combines various sizes of colorful exercise balls, held in place or suspended with conventional drum hardware and thus creating a trap kit configuration in which the spherical surfaces ca...
