Camera Calibration from the Quasi-affine Invariance of Two Parallel Circles
Abstract. In this paper, a new camera calibration algorithm is proposed, which is from the quasi-affine invariance of two parallel circles. Two parallel circles here mean two circl...

Multi-Projector Displays Using Camera-Based Registration
Conventional projector-based display systems are typically designed around precise and regular configurations of projectors and display surfaces. While this results in rendering s...

Wavelet Based Noise Reduction in CT-Images Using Correlation Analysis
Abstract-- The projection data measured in computed tomography (CT) and, consequently, the slices reconstructed from these data are noisy. We present a new wavelet based structurep...
