Informative sensing : theory and applications
… images. We also considered designing an optimal color filter array for single-chip cameras. In this case, the feasible set of projections is highly restricted because multiplexing across pixels is not allowed. Nevertheless, our principle still applies. By minimizing the uncertainty of the …

The resolution enhancements of real-time captured images
… addresses in three ways. First, an improved color filter array interpolation algorithm is proposed, which offers high accuracy with reasonable performance. Second, the thesis discusses a mechanism in which real-time user feedback is given to aid in the capture and creation of mosaic images. …

Modeling and Analysis of Optical Blur for Everyday Photography
… crosstalk, and pixel multiplexing due to the color-filter-array. The coupling of the distortions are critical to deblurring quality but is non-trivial to invert efficiently. We propose a practical image formation model that captures all three distortions while enables fast restoration. Third, …

Fuzzy techniques for noise removal in image sequences and interval-valued fuzzy mathematical morphology
… processing techniques. A preprocessing module to filter the images often becomes necessary. After an introduction to fuzzy set theory and image processing, in the first main part of the thesis, several fuzzy logic based video filters are proposed: one filter for grayscale video sequences corrupted …

Denoising and Demosaicking of Color Images
Most digital cameras capture images through Color Filter Arrays (CFA), and reconstruct the full color image from the CFA image. Each CFA pixel only captures one primary color component at each pixel location; the other primary components will be estimated using information from neighboring pixels. …

Breaking Symmetry: A Study of Novel Phenomena in Asymmetric Nanoplasmonic Systems
<p>Offering tailorable optical properties not achievable with symmetric or periodic optical materials, chiral, weakly disordered, deterministic aperiodic, quasiperiodic and random structures make up a new wave of asymmetric optical systems demonstrating unprecedented control of light compared to …
