High-contrast Coronagraphic Techniques

EAS Publications Series, 2010
The direct detection of very faint companions to bright stars requires the development of effective high-contrast detection techniques, and the past decade has seen remarkable conceptual and instrumental progress in this area. New coronagraphic and interferometric techniques are regularly being deployed for on-sky tests and observations, and extreme ...

Nonlinear technique for the enhancement of extremely high contrast images

SPIE Proceedings, 2008
An adaptive technique for image enhancement based on a specifically designed nonlinear function is presented in this paper. The enhancement technique constitutes three main processes-adaptive intensity enhancement, contrast adjustment, and color restoration.

A New Technique for High Contrast Development in Rapid Processing

The Journal of Photographic Science, 1984
AbstractA rapid developing system with a high contrast comparable to that of the lith system is described. The mechanism of the high contrast development has been investigated by using a model system. It has been found that a considerable amount of semiquinone is formed in a high pH and high-sulphite developer and a specific retardation effect by some ...

An Adaptive and Non Linear Technique for Enhancement of Extremely High Contrast Images

35th IEEE Applied Imagery and Pattern Recognition Workshop (AIPR'06), 2006
In night time surveillance, there is a possibility of having extremely bright and dark regions in some image frames of a video sequence. A novel non linear image enhancement algorithm for digital images captured under such extremely non-uniform lighting conditions is proposed in this paper. The new technique constitutes three processes viz.

TECHNIQUE FOR SELECTIVE MICROANGIOGRAPHY OF SKIN FLAPS WITH HIGH CONTRAST AND FINE DETAIL

Journal of Reconstructive Microsurgery, 2000
The technical factors of microangiography were studied, and the authors found that the main limiting factors in resolution were the injection pressure of the contrast medium and the thickness of the materials. A gentle manual hand pressure injection, with the aid of visual monitoring under the operating microscope, were keys to obtaining beautiful ...
