Theories of interorganizational coordination propose that that the fit between information processing capabilities (structure, process and technology) and information processing needs (environmental, partnership and task uncertainty) is a strong determinant of IOS performance. Recently, electronic marketplaces have replaced many traditional interorganizational systems (IOS). While traditional I...

Fatigue detection has many applications, one of them is intelligent transportation for accident prevention. It challenging to detect driver fatigue adopting photometric stereo and 3D fatigue-related facial action unit identification. During reconstruction shadows are encountered, causing error, therefore, accurate shadow removal crucial. This study presents a novel snake based approach handling...

This paper presents a novel approach to the problem of computing the matching-cost for stereo vision. The approach is based upon a Convolutional Neural Network that is used to compute the similarity of input patches from stereo image pairs. In combination with state-ofthe-art stereo pipeline steps, the method achieves top results in major stereo benchmarks. The paper introduces the problem of s...

In deep learning-based local stereo matching methods, larger image patches usually bring better accuracy. However, it is unrealistic to increase the size of patch without restriction. Arbitrarily extending will change method into global method, and accuracy be saturated. We simplified existing Siamese convolutional network by reducing number parameters propose an efficient CNN based structure, ...

Different auction-based approaches have been used to allocate resources in Grids, but none of them provide the design choice for a specific economic model while considering the interest of all participants in the market. In this paper, we implement an auction-based framework for producer and consumer matchmaking in an ad-hoc Grid. In ad-hoc Grids, where the availability of resources and tasks i...

The ambiguity of natural language can be an important source of creative concepts. In compositional languages, a many-to-many network of associations exists linking concepts by the polysemy and synonymy of utterances. This network allows utterances to represent the combination of concepts, forming new and potentially interesting compound meanings. At the same time, new experiences of external a...

Let A = {a1, a2, . . . , as} and {b1, b2, . . . , bt} with s+r = n, the many to many point matching with demands and capacities matches each point ai ∈ A to at least αi and at most α ′ i points in B, and each point bj ∈ B to at least βj and at most β ′j points in A for all 1 ≤ i ≤ s and 1 ≤ j ≤ t. In this paper, we present an O(n) time and O(n) space algorithm for this problem.

This study investigates the geometric accuracy of DSMs and orthoimages, which are obtained from high resolution satellite stereo pairs of in-track, cross-track and mixed satellite images. Four IKONOS and two QuickBird panchromatic images are used to constitute 15 stereo pairs, and are processed to generate DSMs and orthoimages. A geometric stereo model, which represents the stereo acquisition g...
