Dense image matching methods enable the extraction of 3D surface geometry from images acquired from multiple views. Tpyical applications vary from aerial imaging, where such methods can be used to retrieve digital surface models with high density, up to cultural heritage data recording, where the acquisition of images using digital cameras represents an efficient method to retrieve 3D data for ...

The history of stereo analysis of images dates back more than one hundred years, but stereo analysis of image sequences is a fairly recent subject. Sequences allow time-propagation of results, but also come with particular characteristics such as being of lower resolution, or with less contrast. This article discusses the application of belief propagation (BP), which is widely used for solving ...

Disparity map generation is a significant component of vision-based driver assistance systems. This paper describes an efficient implementation of a belief propagation algorithm on a graphics card (GPU) using CUDA (Compute Uniform Device Architecture) that can be used to speed up stereo image processing by between 30 and 250 times. For evaluation purposes, different kinds of images have been us...

The limitations of estimating structure from either stereo or motion alone can be addressed by the use of stereo image sequences; however, many existing techniques for processing stereo sequences rely on having accurate feature correspondences initially. In this paper, we present an iterative feature matching and shape reconstruction algorithm. The proposed method simultaneously resolves matchi...

Today, communication devices are evolving towards friendly–user interactivity while permanently eyeing towards 3D display technologies. As such, 3D face generation, modelling and animation techniques are in the frontline to design realistic animated 3D talking faces. Simple, reliable and economic, 2D image processing techniques have been widely used to reconstruct 3D faces. This paper focuses o...

Stereo video is regarded as an important developing trend of video technology and there is an increasing need to develop efficient and perceptually consistent methods for stereo video quality evaluation in the fields of stereo video signal processing. In this paper, a perceptual metric for stereo video quality evaluation is proposed based on the state-of-the-art physiological and psychological ...

The ability to obtain the accurate three-dimensional position information in the presence of limited sensor resolution is a crucial task in computer vision and other triangulation systems. Sensors for computer processing applications produce sampled quantized data, whose spatial resolution is determined by limits in device technology and bandwidth. In computer vision and photogrammetry, normall...

This paper describes analytical and digital photogrammetric methods of a stereo pair of scanning electron microscope (SEM) photographs. Analytical method was applied to a triplet of stereo SEM photographs of an impression left by the diamond indenter of Vicker's hardness tester. The height error of the three dimensional measurement was ±5% and the precision is sufficient for surface shape analy...
