This paper describes a method for stereoscopic rectification with geometric distortion minimisation, to generate suitable image pairs for 3D viewing applications. The current state of the art technique is not optimal as it lacks appropriate mathematical constraints. We present a new approach that enforces the same distortion minimisation criterion with more computational efficiency whilst also ...

Most algorithms in 3-D Computer Vision rely on the pinhole camera model because of its simplicity, whereas video optics, especially wide-angle lens, generates a lot of non-linear distortion. In some applications, for instance in stereo vision systems and robotic systems, this distortion can be critical. Camera calibration consists of finding the mapping between the 3-D space and the camera plan...

In the studies related to multiple description coding (MDC), applying zero padding not only improves the spatial correlation between descriptions but also increases their sizes. However, as we pad more zeros, the spatial correlation does not improve linearly. Therefore, the distortion is not reduced as the same amount when the size increases. In this paper, we focus on how to efficiently find a...

Attitude of the Small satellite is prone to be affected by external disturbing factors due to its small inertia. As for Beijing-1 small satellite, jitter is induced and exhibited in the images taken while the outside disturbance is intense. The jitter is manifested as jagged lines and edges in the images, leading to distortion of geometric property of the objects. In this paper, properties of t...

In this paper, we present a noble pattern synthesis method of linear and planar array antennas, with non-uniform spacing, for simultaneous reduction of their side-lobe level and pattern distortion during beam steering. In the case of linear array, the Gauss-Newton method is applied to adjust the positions of elements, providing an optimal linear array in the sense of side-lobe level and pattern...

In this paper, calibrating a camera refers to the process of determining the transformation between a 3D object coordinate system and the 2D image coordinate system of the camera. Knowing this transformation, 3D position of a feature point seen in two cameras can be determined by using triangulation. Suppose a distortion-free lens is had, this 3D-2D transformation can be well approximated by a ...

We consider a joint source-channel coding system that protects an embedded wavelet bitstream against noise using a finite family of channel codes with error detection and error correction capability. The performance of this system may be measured by the expected distortion or by the expected number of correctly received source bits subject to a target total transmission rate. Whereas a rate-bas...

In this paper, we introduce a new piecewise linear parameterization of 3D surface patches which provides a basis for texture mapping, morphing, remeshing, and geometry imaging. To lower distortion when flatting a 3D surface patch, we propose a new method to locally calculate straightest distances with cutting planes. Our new and simple technique demonstrates competitive results to the current l...
