A blurred mass subtraction technique has been developed for mammography that will enhance small object contrast and visibility throughout the breast area. The procedure is easy to implement and requires no additional exposure. Perception of low-contrast objects is improved by eliminating extreme light and dark image areas. Contrast of structures within

Image enhancement in ultrasound imaging
2016 24th Signal Processing and Communication Application Conference (SIU), 2016In this paper, two different methods are suggested in order to provide image enhancement in ultrasonic B-mode imaging. By obtaining RF data from two different phantom used to form B-mode image, their spectral characteristics were observed. Then by forming RF envelope from obtained data, conversion of envelope to color image is provided.

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.

Recognition of Enhanced Images
11th International Multimedia Modelling Conference, 2005Image enhancement such as adjusting brightness and contrast is central to improving human visualization of images content. Images in desired enhanced quality facilitate analysis, interpretation, classification, information exchange, indexing and retrieval.

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.

We propose a modification of Wells' et. al. technique for bias field estimation and segmentation of MR images. Replacement of the class other that includes all tissue not modeled explicitly by Gaussians with small variance by a uniform probability density, and amending the EM algorithm appropriately, gives significantly better results.

Enhancing hyperspectral imaging
Nature Machine Intelligence, 2021Hyperspectral imaging can reveal important information without the need for staining. To extract information from this extensive data, however, new methods are needed that can interpret the spatial and spectral patterns present in the images.

The continued application of innovative imaging systems to endoscopic procedures has vastly improved the detection of indiscriminant tissue anomalies. This article describes the fundamental principles of these technologies and reviews the advances of each over the past 18 months, considering their utility in the diagnosis and surveillance of various ...

Color image enhancement is becoming an increasingly important research area. This paper reviews some image enhancement techniques developed specifically for gray-images and presents an extension and application to color images of a method that involves the decomposition of an image into background and texture components.
