In this paper we present a simple and affordable method to generate high quality video from a high dynamic range scene. It is performed without utilizing extra lighting, neither alternating exposures, nor operating with dual-camera set-ups. Our input is an interlaced video alternating row pairs with different ISO values, as some DSLR camera models can provide. The proposed algorithm involves tw...

progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. both general services administration (gsa) and united states department of d...

A framing camera incorporating an ultra high resolution CCD detector array comprised of 9,216 x 9,216 pixels is discussed. The detector array measures 8 x 8 centimeters and has been scaled to be fabricated in one piece on a 5inch diameter silicon wafer. Pixel size is 8.75 x 8.75 microns which gives 57 lp/mm resolution. The detector array features a two frame per second readout capability which ...

In this work, we give parallel transport frame of a curve and we introduce the relations between the frame and Frenet frame of the curve in 4-dimensional Euclidean space. The relation which is well known in Euclidean 3-space is generalized for the …rst time in 4-dimensional Euclidean space. Then we obtain the condition for spherical curves using the parallel transport frame of them. The conditi...

Robotic systems can achieve real-time visual odometry by extracting a fixed number of invariant keypoints from the current camera frame, matching them against keypoints from a previous frame, and calculating camera motion from matching pairs. If keypoints are selected by response only they can become concentrated in a small image region. This decreases the chance for keypoints to match between ...

Steel Plate Shear Wall (SPSW) is an emerging seismic load-resistant system that, compared to other systems, enjoys the advantages of stable ductile behavior, fewer detailing requirements, rapid constructability, and economy. American seismic provisions decree that a SPSW should be designed as a moment frame with a web infill plate. Specifically, in case of buildings taller than 160 ft, it decre...

Whenever approximate 3D geometry is projectively texture-mapped from different directions simultaneously, annoyingly visible aliasing artifacts are the result. To prevent such ghosting in projective texturing and image-based rendering, we propose a new GPU-based rendering strategy and a new, viewdependent definition of ghosting. The algorithm is applicable to any kind of image-based rendering m...

Rapid camera rotations (e.g. camera shake) are a significant problem when real-time computer vision algorithms are applied to video from a handheld or head-mounted camera. Such camera motions cause image features to move large distances in the image and cause significant motion blur. Here we propose a very fast method of estimating the camera rotation from a single frame which does not require ...

In this paper, we investigate the issue of accurate estimation of the three-dimensional (3D) coordinates of a static scene from real images, combining xation and stereo cues. We may need to compute 3D data in many applications: vehicle positioning and maneuver, object observation and recognition, moving or xed obstacle avoidance, 3D mapping for surveillance, etc. More speci cally, we discuss th...

Augmented Reality (AR) tries to seamlessly integrate virtual content into the real world of user. Ideally, would behave exactly like objects. This necessitates a correct and precise estimation user’s viewpoint (or that camera) with regard content’s coordinate system. Therefore, real-time establishment 3-dimension (3D) maps in scenes is particularly important for augmented reality technology. So...
