Image compression is a technique used to reduce the storage required to save an image. The existing image coding methods cannot support content based image compression and enlargement for arbitrary resolution display devices. In multimedia communications, image retargeting is generally required at the user end. The work presented in this paper addresses the increasing demand of visual signal de...

The system propose a video retargeting algorithm to resize images based on the extracted saliency information from the compressed domain. The system utilizes DCT coefficients in JP2 bit stream to perform saliency detection with the consideration of the human visual sensitivity. Valuable retargeting requires emphasize the main satisfied while retain immediate context with minimal visual deformat...

Aims and objectives: To translate and validate a Taiwanese version of the Self-Efficacy for Appropriate Medication Use Scale (SEAMS). Background: The major barrier in the management of atrial fibrillation is the lack of selfefficacy to medications adherence. Patients’ knowledge of the nature of atrial fibrillation and cardiovascular, cerebrovascular risk factors and anticoagulants is a signific...

Polygonal meshes are widely used to represent the shape of 3D objects and the generation of multi-resolution models has been a significant research topic in computer graphics. In this paper, we demonstrate how to generate multi-resolution models through 2D image processing techniques. The goal of generating multi-resolution models is accomplished by resizing the corresponding geometry images of...

We present a high-efficiency approach to optimally enhance image composition using a crop-andwarp-based algorithm. We have designed a piecewise quadratic aesthetic energy function with linear inequality constraints that measures the distance between original positions and the aesthetic target positions of visual elements, to assess the target image composition. The target image is cropped by a ...

T he knuckleball is perhaps the most mysterious of baseball pitches. It is thrown slower than normal pitches, it is barely spinning, and it appears to float to home plate. Its motion seems to be very unpredictable by anyone: the batter, the catcher, and even the pitcher himself. Moreover, there is a common perception that a knuck-leball does not follow a smooth path to home plate, but instead "...

Multireference configuration interaction calculations have been performed on the excited state energy surfaces of the methyleneimmonium cation using recently developed methods for the computation of analytic gradients and nonadiabatic coupling terms. Excited-state structures and minima on the crossing seam have been determined. It was found that the topology of the methyleneimmonium surfaces is...

We propose a novel space deformation method based on domain-decomposition to animate character skin. The method supports smoothness and local controllability of deformations, and can achieve interactive interpolating rates. Given a character, we partition it into multiple domains according to skinning weights, and attach each to a linear system, without seam artifacts. Examples are presented fo...

We develop a canonical Wick rotation-rescaling theory in 3-dimensional gravity. This includes (a) A simultaneous classification: this shows how generic maximal globally hyperbolic spacetimes of arbitrary constant curvature, which admit a complete Cauchy surface, as well as complex projective structures on arbitrary surfaces, are all different materializations of “more fundamental” encoding stru...

We propose the space of axis-aligned deformations as the meaningful space for content-aware image retargeting. Such deformations exclude local rotations, avoiding harmful visual distortions, and they are parameterized in 1D. We show that standard warping energies for image retargeting can be minimized in the space of axis-aligned deformations while guaranteeing that bijectivity constraints are ...
