In this paper we will present a novel approach of using surface patches for Image Based Rendering. Based on image sequences acquired with a freely moving portable multi-camera-rig we can extrapolate novel views of complex real scenes in realtime. The cameras are calibrated from the image sequence itself and dense depth maps are computed for each camera view using an improved multiview depth est...

Important scene information may be relayed to a blind person via mobility aids that incorporate an image to sound mapping. However, these devices are frequently both tiring and stressful to use. A new display technique, which combines a stereo edge depth map with a cartoonlike scene representation is described. Experimental results are included that demonstrate the effectiveness of the algorithm.

View-based 3D video streaming requires the compression and transmission of depth maps along with the video sequence. The requirements for representing these depth maps include moderately high compression, preservation of depth discontinuities, low complexity decoding, and to be in a form that is suitable for real-time rendering using graphics cards. This motivates a meshbased representation for...

This paper presents a method of converting a 2D still photo containing the head & shoulders of a human (e.g. a passport photo) to pseudo-3D, so that the depth can be perceived via stereopsis. This technology has the potential to be included in self-serve photo booths and, also as an added accessory (i.e. software package) for digital still cameras and scanners. The basis of the algorithm is to ...

Reliable depth estimation is important to many autonomous robotic systems and visual control algorithms. The Microsoft Kinect is a new, low cost game controller peripheral that calculates a depth map of the environment with good accuracy and high rate. In this paper we use the calibrated output of the depth sensor to obtain an accurate absolute depth map. Subsequently by using a Randomized Houg...

investigation of desertification trend needs understanding of phenomena creating changes singly or action and reaction together in the manner that these changes were ended up in land degradation. in investigation of pedological criterion onland degradation in quaternary rock units, first, a part of the rude-shoor watershed area was selected. after distinguishing target area, maps of slope class...

Coastal Fars gravimetry project in Fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. The Lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. Depth structural model of this anticline made in previous studies was based on geological evidences and structural geology measurements. In order t...
