Abstract:

The author presents a feature-guided convolution method for rendering a 3D triangular mesh. In Their work, they compute feature directions on the vertices of a mesh and generate noise on the faces of a mesh. After projecting the directions and noise into 2D image space, the author executes convolution to render the mesh. They used three feature directions: a principal direction, the tangent of an isocurve of view-dependent features, and the tangent of an isophote curve. By controlling the value of noise, the author can produce several non-photorealistic rendering effects such as pencil drawing

Abstract:

To provide with an effective method for non-photorealistic rendering for computer generated images with sketch artistic appearances from 2D images motivates our work in this paper. The character of lines, details in the source image can be smoothed by the technique of guided filter, and then the abstract smooth appearance of the image can be simulated. In addition, the smooth effect can be enlarged and enhanced by the technique of improved line integral convolution, so the final sketch artistic image can be obtained. Experimental results show that the proposed method can simulate the real sket

Abstract:

The process of creating nonphotorealistic rendering images and animations can be enjoyable if a useful method is involved. We use an evolutionary algorithm to generate painterly styles of images. Given an input image as the reference target, a cloud model-based evolutionary algorithm that will rerender the target image with nonphotorealistic effects is evolved. The resulting animations have an interesting characteristic in which the target slowly emerges from a set of strokes. A number of experiments are performed, as well as visual comparisons, quantitative comparisons, and user studies. The

Abstract:

Image-Based Rendering (IBR) has made impressive progress towards highly realistic, interactive 3D navigation for many scenes, including cityscapes. However, cars are ubiquitous in such scenes; multi-view stereo reconstruction provides proxy geometry for IBR, but has difficulty with shiny car bodies, and leaves holes in place of reflective, semi-transparent windows on cars. We present a new approach allowing free-viewpoint IBR of cars based on an approximate analytic reflection flow computation on curved windows. Our method has three components: a refinement step of reconstructed car geometry g

Abstract:

Shallow depth-of-field (DoF), focusing on the region of interest by blurring out the rest of the image, is challenging in computer vision and computational photography. It can be achieved either by adjusting the parameters (e.g., aperture and focal length) of a single-lens reflex camera or computational techniques. In this paper, we investigate the latter one, i.e., explore a computational method to render shallow DoF. The previous methods either rely on portrait segmentation or stereo sensing, which can only be applied to portrait photos and require stereo inputs. To address these issues, we

In order to overcome these challenges, in this paper we propose to transfer the knowledge of a network learned from natural images to a sketch network - a new deep net architecture which we term as cousin network.

Despite the fact that the second harmonics could provide information sensitive to the structural health condition, the diminutive amplitude of the measured second-order harmonic guided wave still limits the applications of the second-harmonic generation–based nonlinear guided wav

Depth image-based rendering (DIBR) plays an important role in 3D video and free viewpoint video synthesis. However, artifacts might occur in the synthesized view due to viewpoint changes and stereo depth estimation errors. Holes are usually out-of-field regions and disocclusions, and filling them appropriately becomes a challenge. In this paper, a virtual view synthesis approach based on asymmetric bidirectional DIBR is proposed. A depth image preprocessing method is applied to detect and correct unreliable depth values around the foreground edges. For the primary view, all pixels are warped t

The fluoroscopic anatomy of the sacrum can be difficult to understand, and this is why sacroplasty is considered more challenging than ordinary vertebroplasties. Purpose: To demonstrate the planning of the procedure and the effectiveness of treatment with sacroplasty by means of three-dimensional computed tomography (3D CT) by combining multiplanar reconstructions (MPR) and volume-rendering technique (VRT). Material and Methods: Five elderly, osteoporotic patients with intense pelvic

AbstractSubarachnoid haemorrhage (SAH) is a consistent presentation of haemorrhagic stroke of significance to clinicians in neurocritical care, inducing consequent effects on non-neurological systems, while at the same time, rendering the brain vulnerable to secondary physiological insult modifying neurological outcome, despite control of the original point of haemorrhage. Coordinated treatment depends on comprehensive evaluation of both cerebral and systemic physiology, identifying and treating impaired function. The presence of a dedicated neurocritical care team can benefit outcome. Protoco

US National Security Strategy, 2017, mentioned China as a revisionist state, an economic competitor and a challenger. US NSC China declared to compete with China under the guided principles of realism. US actions and strategies make an interesting argument to validate that USA has fallen in the Thucydides Trap, not because China has pushed the US, but because fear has engulfed her and has adopted an appropriate form of war. This article explores the approaches adopted by USA in her Hybrid War against China. It discusses the surge in attacks on China political Center of Gravity. It analyses the

Abstract:

Multiview video plus depth is one of the mainstream representations of 3D scenes in emerging free viewpoint video, which generates virtual 3D synthesized images through a depth-image-based-rendering (DIBR) technique. However, the inaccuracy of depth maps and imperfect DIBR techniques result in different geometric distortions that seriously deteriorate the users’ visual perception. An effective 3D synthesized image quality assessment (IQA) metric can simulate human visual perception and determine the application feasibility of the synthesized content. In this paper, a no-reference IQA metric ba

Abstract:

AbstractThe politics of parenthood is a major battleground in disputes about gender equality. In contemporary debates on parental leave reform, notions about ‘equal’ parenthood and parental ‘choice’ compete. Earmarked leave for fathers, the so-called ‘daddy quota’ – a hallmark of Nordic welfare states, is increasingly being discussed in other types of welfare state. Further increases in earmarked leave is thus of interest to the policy debate in other countries, too. This article examines the reception among political actors in Norway of a proposal in 2008 to divide the existing parental leave

Abstract:

Neurite growth cones detect and respond to guidance cues in their local environment that determine stereotyped pathways during development and regeneration. Micropatterns of laminin (which was found to adsorb preferentially to photolithographically defined hydrophobic areas of micropatterns) were here used to model adhesive pathways that might influence neurite extension. The responses of growth cones were determined by the degree of guidance of neurite extension and also by examining growth cone morphology. These parameters were found to be strongly dependent on the geometry of the patterned
