Image quality and image resolution
2013 Seventh International Conference on Sensing Technology (ICST), 201313 years after the introduction of the first digital airborne mapping camera in the ISPRS conference 2000 in Amsterdam, several digital cameras with more than 100 MPixels per image have been made available. They are now well established in the market and have replaced the analogue mapping cameras.

Analytica Chimica Acta, 2008
Imaging in Raman spectroscopy is a valuable tool for analytical chemistry. Although molecular characterization at micron level is achieved for many applications, it usually fails producing chemical images of micron size samples as expected in chemical, environmental and biological analysis.

Image super-resolution via multi-resolution image sequence
2013 International Conference on Wavelet Analysis and Pattern Recognition, 2013A novel super-resolution reconstruction algorithm of multi-resolution image sequence integrating the improved super-resolution reconstruction based on neighbor embedding with scale invariant feature transform (SIFT) is proposed in this paper. Firstly, SIFT key points in images are extracted.

High-resolution imaging ellipsometer
Applied Optics, 2002We report on a novel imaging ellipsometer using a high-numerical-aperture (NA) objective lens capable of measuring a two-dimensional ellipsometric signal with high resolution. Two-dimensional ellipsometric imaging is made possible by spatial filtering at the pupil plane of the objective.

High resolution stereoscopic imaging
Applied Optics, 1983In the usual method of stereoscopic imaging by observation at two different angles the resolution obtainable is poor. By imaging in a confocal scanning optical microscope with two different angles of observation the resolution is substantially improved. The method is applicable to phase and amplitude objects.

High resolution fluorographic imaging(?)
The British Journal of Radiology, 1985In the past 100 mm and 105 mm fluorography has played a role subordinate to full-size radiography in diagnostic radiology. Given the improvements in image quality achieved since the introduction of caesium iodide input screens (Baiter & Kuhl, 1980), and also given the growing awareness among the radiological community of the economic advantages of ...

Color image resolution conversion
IEEE Transactions on Image Processing, 2005In this paper, we look at the problem of spatially scaling color images. We focus on an approach that takes advantage of the human visual system's color spatial frequency sensitivity. The algorithm performs an efficient least-squares (LS) resolution conversion for the luminance channel and a low-complexity pixel replication/reduction in the chrominance
