A service system is a popular concept in academia and industry. At the same time, it is a challenging concept to represent, due to its recursive nature and difficulty to relate it to entities in reality. In this paper we present an ontology for modeling service systems using the SEAM systemic method. Our ontology represents an updated and minimalistic version of the existing SEAM service modeli...
Steganalysis and forgery detection in image forensics are generally investigated separately. We have designed a method targeting the detection of both steganography and seam-carved forgery in JPEG images. We analyze the neighboring joint density of the DCT coefficients, and reveal the difference between untouched image and the modified version. In realistic detection, untouched image and the mo...
In gen(-, ral ,a seam may f ai I as a result of longitudinal or transverse loading. Previous workers have reported transverse seam strength to be a prime requirement in most cases of Joining woven fabrics by the means of sewn seams. Transverse seam breaks can be divided into two types: Type I in which only the sewinq thread breaks (with Lhe fabric undamaged); and Irype II in which only the fabr...
Many aesthetic models in computer vision suffer from two shortcomings: 1) the low descriptiveness and interpretability of those hand-crafted aesthetic criteria (i.e., nonindicative of region-level aesthetics), and 2) the difficulty of engineering aesthetic features adaptively and automatically toward different image sets. To remedy these problems, we develop a deep architecture to learn aesthet...
The development of the south polar Chasma Australe re-entrant has been discussed for several years and a variety of theories including eolian, aquatic, subglacial and tectonic mechanisms have been proposed for its formation. Morphological observations and studies of recent imagery support the idea of successive headward erosion and removal of volatile–rich sub–surface material combined with col...
A thin coal seam mined as a protective coal seam above a gas outburst coal seam plays a central role in decreasing the degree of stress placed on a protected seam, thus increasing gas permeability levels and desorption capacities to dramatically eliminate gas outburst risk for the protected seam. However, when multiple layers of coal seams are present, stress-relieved gas from adjacent coal sea...
In recent years, image retargeting has been an active research topic due to the rapid growth of mobile devices and display screens with different resolutions and aspect ratios. To address this problem, various content-aware image-retargeting approaches have been proposed to retarget images while preserving important regions and minimizing distortions. In our research, the goal is to propose a n...
We have been studying an in-situ 3D modeling and authoring system, AR Diorama. In the AR Diorama system, a user is able to reconstruct a 3D model of a real object of concern and describe behaviors of the model by stroke input. In this article, we will introduce two ongoing studies on interactive 3D reconstruction techniques. First technique is feature-based. Natural feature points are first ext...
With the increasing popularity of smartphones and similar mobile devices, the demand for media to consume on the go rises. As most images and videos today are captured with HD or even higher resolutions, there is a need to adapt them in a content-aware fashion before they can be watched comfortably on screens with small sizes and varying aspect ratios. This process is called retargeting. Most d...
