Enhancing the Image of Nursing
JONA: The Journal of Nursing Administration, 1989A Task Force from a Midwestern teaching hospital developed a comprehensive strategy to enhance the image of nursing in both the hospital and the community. Nursing administrators will find the Task Force's process and outcomes useful in addressing the image of nursing in their own institutions.

Gastrointestinal Endoscopy, 2011
The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee provides reviews of emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methodology is used, with MEDLINE and PubMed literature searches to identify pertinent clinical studies on the topic.

Publisher Summary With image enhancement, the visibility of selected features in an image can be improved, but the inherent information content cannot be increased. The design of a good image enhancement algorithm should consider the specific features of interest in the microscopic image and the imaging process itself. The image enhancement algorithms

Journal of Gastroenterology, 2011
Narrow band imaging (NBI) can emphasize images of the surface microvasculature of lesions, because the central wavelengths of the NBI filter are 415 and 540 nm and these wavelengths are well absorbed by hemoglobin. Flexible spectral imaging color enhancement (FICE) increases the contrast in depictions of mucosal lesions.

Radiology, 1980
The enhancement of radiographic and fluoroscopic images using simple video analog techniques is described. In each instance, both the degree of enhancement and the features of the image to be enhanced are under the direct control of the radiologist. Noise is suppressed with a sharp cut-off, low-pass filter. Three types of analog circuits are discussed.

Optical Society of America Annual Meeting, 1991
Blockwise transform image enhancement techniques are discussed. Previously, transform image enhancement has usually been based on the discrete Fourier transform (DFT) applied to the whole image. Two major drawbacks with the DFT are high complexity of implementation involving complex multiplications and additions, with intermediate results being complex

Enhanced Visualization of Hyperspectral Images
IEEE Geoscience and Remote Sensing Letters, 2010An enhanced visualization algorithm for hyperspectral images (HSI) is presented in this paper. The visualization is based on the projection onto color matching functions of the human vision system. A contrast enhancement procedure is introduced making use of multiband gradient information.

Image detection and enhancement
Applied Optics, 1981An optimal filtering approach is taken to the problem of detecting and enhancing a photographic image immersed in background or noise. The minimum mean square error criterion is shown to be not relevant to the optical employment of the Wiener filter.

Image enhancement and restoration
1975The aim of collecting data is to gain meaningful information about a phenomenon of interest. Unfortunately, often the phenomenon is not a direct physical observable. Instead, e.g., the data at hand may be a linear superposition of the desired quantities.

Image enhancement is a well established field in image processing. The main objective of image enhancement is to increase the perceptual information contained in an image for better representation using some intermediate steps, like, contrast enhancement, debluring, denoising etc.
