Video inpainting consists in recovering the missing or corrupted parts of an image sequence so that the reconstructed sequence looks natural. For each frame, the reconstruction has to be spatially coherent with the rest of the image and temporally with respect to the reconstructions of adjacent frames. Most of existing methods only focus on inpainting foreground objects moving with a periodic m...

Coherent judgment is a cardinal feature of rational cognition. Six experiments revealed systematic violations of coherence in probability judgment in which participants assigned different probabilities to mathematically equiprobable events. Experiments 1-5 revealed a strict refocusing effect: Compared to an occurrence frame, a non-occurrence frame resulted in higher estimates if base-rate evide...

Motion segmentation is traditionally coupled with motion detection, where each image region corresponds to a particular motion model which accounts for the temporal changes in the region. Using the motion model to estimate the second frame from the rst frame, for example, should give a very low prediction error in the corresponding region. To relax the need for accurate motion models, it is pro...

A major challenge in video segmentation is that the foreground object may move quickly in the scene at the same time its appearance and shape evolves over time. While pairwise potentials used in graph-based algorithms help smooth labels between neighboring (super)pixels in space and time, they offer only a myopic view of consistency and can be misled by inter-frame optical flow errors. We propo...

Sophisticated video processing effects require both image and geometry information. We explore the possibility to augment a video camera with a recent infrared time-of-flight depth camera, to capture high-resolution RGB and low-resolution, noisy depth at video frame rates. To turn such a setup into a practical RGBZ video camera, we develop efficient data filtering techniques that are tailored t...

This paper presents a novel interface for 3D modeling in augmented reality, aiming at developing a form gradually in the early phase of a product design process. Previous VR/AR based modeling systems have focused largely on geometrical algorithms and system performance issues. From a designers’ perspective, this study analyzed the conventional form creating processes and developed a more intuit...

Rasterization hardware provides interactive frame rates for rendering dynamic scenes, but lacks the ability of ray tracing required for efficient global illumination simulation. Existing ray tracing based methods yield high quality renderings but are far too slow for interactive use. We present a new parallel global illumination algorithm that perfectly scales, has minimal preprocessing and com...

an experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. the first specimen was a reinforced concrete frame with solid-brick infill. the second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. the last specimen was a reinforced concrete frame without any infill. these three specimens were tested by pseudostatic method. di...

A polar-coded transmission (PCT) scheme with joint channel estimation and decoding is proposed for channels unknown state information (CSI). The CSI estimated via successive cancellation (SC) the constraints imposed by frozen bits. SC list an outer code improves performance, including resolving a phase ambiguity when using quadrature phase-shift keying (QPSK) Gray labeling. Simulations 5G polar...
