In this paper, we present ARTTag, an aesthetic fiducial marker system, of which the design development can be performed with any color, texture, shape, or other features as long as circle pairs are integrated. By utilizing the projective properties of circular features, ARTTag is appropriate for detection, identification, and camera-based registration in augmented reality (AR) applications.

In this work, we propose a Virtual Reality based solution to provide a more natural and intuitive environment for controlling electrical operation centers. The research is being carried out with the collaboration of one electric company called Cemig. The novelty of this approach is the ability operators will have to manage the electric system and its electric components by being immersed within a 3D world, reflecting the very true arrangement found in the real electrical substation. Besides, the solution has been designed in a way to provide the operator with all supervisory data in the same virtual environment. We have conducted experiments with the electric company operators Mental efforts to understand the reality of the field have been reduced, according to Cemig's employees. They also claim that a unique environment with all data integrated is very important for taking engineering decisions.

Diffusion curves [Orzan et al. 2008] (DCs) has risen as an attractive vector primitive for representing complex colour gradients. Its flexible mathematical definition, taking curves with colour values as input, can be easily adopted by artists and designers because curves represent an intuitive approach to 2D drawing and design. However, the (Laplacian) diffusion process is computationally expensive and naive DCs (solving the large sparse PDE naively) are consequently unattractive as a practical vector graphics primitive. Lots of work has therefore been undertaken to identify a practical framework for defining and rendering DCs.

We propose a dynamic spatial augmented reality (SAR) system with effective machine learning techniques and edge-based object tracking. Real-time 3D pose estimation is the significant problem of projecting images on moving objects. However, camera-based feature detection is difficult, because most targets have a texture-less surface. Image projection and projected images also interfere with detection. Obtaining 3D shape information with stereo-paired cameras [Resch et al. 2016] is still a time-consuming process, and using a depth sensor with IR [Koizumi et al. 2015] is still unstable and have a fatal time-delay for the dynamic SAR. Therefore, we quickly and robustly estimate the 3D pose of the target objects by using effective machine learning with IR images. And by the combined use of high-speed edge-based object tracking, we realize a stable and low-delay SAR for moving objects.

The representation of texture is a major concern during fabrication and manufacturing in many industries. Thus, the approach for fabricating everyday objects and the digital expression of their textures before fabrication process has become a popular research area. Although it is easy to change the texture of objects in the digital world (i.e. just setting texture parameters), it is difficult to achieve this in the real world.

Digital characters are common in modern films visual effects and the demand for digital actors has increased during the past few years. The success of digitally created actors is related to their believability and, in particular, the realism of the animation and simulation of their faces. Facial expressions in computer graphics are commonly obtained through linear vertex interpolation techniques such as blend shapes. These enable high artistic control and fast interaction, but cannot properly reproduce collisions or other physical phenomena such as gravity and inertia. These effects can be achieved by applying simulation techniques over the animated facial geometry (e.g. muscle simulation), but could potentially alter the look of the desired facial expression and produce inconsistencies with the work approved in animation. Moreover, animating such muscle rigs can be very cumbersome.

Users always got bad experiences while using the general virtual reality head-mounted displays (HMDs) because of the low pixel density through optical lenses. For this reason, the narrow field-of-view (FoV) and high pixel density are the main goals we are going to pursue in the near-field video see-through augmented reality (AR) applications with sophisticated operations, such as the biological observation with AR microscope (e.g. Scope+ [Huang et al. 2015]), the AR surgery simulation, and telescope applications. Therefore with high resolution to see tiny objects clearly is the most important concern in this paper.

We present a fully automatic approach to real-time 3D face reconstruction from monocular in-the-wild videos. We use a 3D Morphable Face Model to obtain a semi-dense shape and combine it with a fast median-based super-resolution technique to obtain a high-fidelity textured 3D face model. Our system does not need prior training and is designed to work in uncontrolled scenarios.

These large collections of shapes can provide inspiration for designers or make it possible to synthesize new shapes by combining different parts from already existing shapes, which can be both easy to learn and a fast way of creating new shapes.

In 2009, the ACM/SIGGRAPH Education Committee established an Undergraduate Research Alliance [Undergraduate Research Alliance] to foster the development of undergraduate research, in computer graphics and interactive techniques, across all related disciplines. Since its inception, the Alliance has hosted sessions at the annual SIGGRAPH conferences to allow educators and other the chance to discuss what they have accomplished and what still needs to be done. If we in the SIGGRAPH community wish to continue to expand the envelope of knowledge, it is necessary that we engage students in the exploration of new ideas as early as possible in their education. The purpose of this poster, therefore, is to present a case study for undergraduate research with the hopes that it spurs others to join in this endeavor.
