In a recent paper, Shawn Green and Daphne Bavelier show that playing an action video game markedly improved subjects performance on a range of visual skills related to detecting objects in briefly flashed displays. This is noteworthy as previous studies on perceptual learning, which have commonly focused on well-controlled and rather abstract tasks, found little transfer of learning to novel st...

We propose a scheme to recover the eye-contact between multiple users in Shared Mixed Reality Space. The eye-contact in a collaborating mixed reality space is lost as the side effect of wearing head-mounted displays (HMDs). We developed a method to synthesize 3D facial video in order to recover eye-contact which was lost by an HMD. Our method can synthesize facial video with arbitrary posture a...

High dynamic range (HDR) images and video contain pixels, which can represent much greater range of colors and brightness levels than that offered by existing, standard dynamic range images. Such “better pixels” greatly improve the overall quality of visual content, making it appear much more realistic and appealing to the audience. HDR is one of the key technologies of the future imaging pipel...

High resolution displays are increasingly popular, requiring most of the existing video content to be adapted to higher resolution. State-of-the-art super-resolution algorithms mainly address the visual quality of the output instead of real-time throughput. This paper introduces FAST, a framework to accelerate any image based super-resolution algorithm running on compressed videos. FAST leverag...

When interlaced scan (IS) is used for television transmission, the received video must be deinterlaced to be displayed on progressive scan (PS) displays. To achieve good performance, the deinterlacing operation is typically computationally expensive. We propose a receiver compatible approach which performs a deinterlacing operation inexpensively, with good performance. At the transmitter, the s...

We propose a fast, yet simple algorithm to find the Region of Interest (ROI) from a compressed MPEG video bitstream, with partial decoding. We have used the properties of the Human Visual System (HVS), applied in the DCT domain, to extract the ROIs. Though a lot of work has been done to obtain ROIs in images based on the HVS, all these systems work in the pixel domain. However, finding the ROIs...

FIG. 1. The image shows the HIV replication cycle, illustrated in LEGO mosaic. A full movie in stop action LEGO can be viewed at www.bushmanlab.org/lego. The video displays how the HIV virus binds to cells, how preintegration complexes enter the nucleus, how HIV DNA becomes integrated into human DNA, and how HIV particles assemble. The movie was made using frames made of LEGO pieces, which were...

Three alternatives to the traditional head mounted Virtual Reality display are described. One configuration is the Virtual Holographic Workstation; an external stereo CRT viewed by a user wearing head tracking stereo shutter glasses. Another is a Computer Augmented Reality camcorder, where virtual objects are composited onto live video using six axis tracking information about the location of t...

Omnidirectional image and video, also known as 360 image and 360 video, are gaining in popularity with the recent growth in availability of cameras and displays that can cope with such type of content. As omnidirectional visual content represents a larger set of information about the scene, it typically requires a much larger volume of information. Efficient compression of such content is there...
