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...

In this work, we show how the decomposition of a problem into a set of simpler and independent subproblems can be applied to automatic configuration. In particular, we describe a dynamic decomposition technique exploiting the compositional structure of complex objects. We show experimentally that such a decomposition can give greater improvements in the reduction of the computational effort tha...

A new issue in texture analysis is its extension to temporal domain, known as dynamic texture. Many real-world textures are dynamic textures whose retrieval from a video database should be based on both dynamic and static features. In this article, a method for extracting features revealing fundamental properties of dynamic textures is presented. Their interpretation enables qualitative request...
