Illumination variation is a big problem in object recognition, which usually requires costly compensation prior to classification. It would be desirable have an image-to-image transform, uncovers only the structure of for efficient matching. In this context contribution our work two-fold. First, we introduce illumination invariant local features detection. For computation propose modified census transform enhances original Zabih and Woodfill. We show some shortcomings how get over them with...

Several of the more important endmember-finding algorithms for hyperspectral data are discussed and some their shortcomings highlighted. A new algorithm - iterated constrained endmembers (ICE) which attempts to address these is introduced. An example its use given. There also a discussion advantages disadvantages normalizing spectra before application ICE or other algorithms.

Hub networks play an important role in many transportation and telecommunications systems. This paper introduces a new model called the hub arc location model. Rather than locate discrete facilities, this locates arcs, which have reduced unit flow costs. Four special cases of general are examined detail. We provide motivation for models, present examples optimal solutions, using data U.S. air passenger traffic. Results used to compare costs, locations, locations with corresponding median...

Understanding potential future influence of environmental, economic, and social drivers on land-use sustainability is critical for guiding strategic decisions that can help nations adapt to change, anticipate opportunities, cope with surprises. Using the Land-Use Trade-Offs (LUTO) model, we undertook a comprehensive, detailed, integrated, quantitative scenario analysis Australia's agricultural land from 2013–2050, under interacting global change domestic policies, considering key...

The study of norms is paramount importance in understanding human behavior. An interdisciplinary literature, using varying definitions and conceptions, shows when why emerge spread, what form they can take, how are enforced. Here, we focus on theoretical empirical literature that treats as a factor influencing We first present new taxonomy norms, which builds upon merges previous taxonomies, to distinguish between different types enforcement mechanisms. then provide conceptual framework...

The problem of locating hub facilities arises in the design transportation and telecommunications networks. p-hub median belongs to a class discrete location-allocation problems which all hubs are fully interconnected. Nonhub nodes may be either uniquely or multiply allocated hubs. uncapacitated total number hubs, p is specified priori. We describe novel exact-solution approach for solving multiple-allocation case show how similar method can adapted more difficult single-allocation case....

A companion paper (Campbell et al. 2005) introduces new hub arc location models and analyzes optimal solutions, with special attention to spatial pattens relationships. This provides integer programming formulations solution algorithms for these problems. We describe two approaches in detail compare their performance, using standard data sets. present implementation details show how can be fine tuned based on characteristics of the data.

In this paper we use a divide-and-conquer approach to tackle large-scale optimization problems with overlapping components. Decomposition for an problem is challenging as its components depend on one another. The existing decomposition methods typically assign all the linked decision variables into group, thus cannot reduce original size. To address issue modify Recursive Differential Grouping (RDG) method decompose problems, by breaking linkage at shared multiple evaluate efficacy of our...

The problem of scheduling aircraft landings on one or more runways is an interesting that similar to a machine job with sequence-dependent processing times and earliness tardiness penalties. aim optimally land set planes several in such way separation criteria between all pairs (not just successive ones) are satisfied. Each plane has allowable time window as well target time. There costs associated landing either earlier later than this In paper, we present specialized simplex algorithm...

Due to the ongoing biodiversity crisis, many species including great apes like chimpanzees are on brink of extinction. Consequently, there is an urgent need protect remaining populations threatened species. To overcome catastrophic decline biodiversity, biologists and gamekeepers recently started use remote cameras recording devices for wildlife monitoring in order estimate size populations. However, manual analysis resulting image video material extremely tedious, time consuming, cost...
