Image enhancement can effectively improve the perception of information from images. This paper provides a comparative study of enhancement approaches applied to digital images with special emphasis on medical images. The paper is organized as follows: Section I gives general introduction to image enhancement approaches along with their critical review.(More)
Medical sciences currently rely on the imaging technology and post processing of these medical images in order to diagnose the diseases. The acquisition of such images may get affected by inherent noise which can lead to false perception of the diagnostic image. To perceive these images correctly the effective image enhancement techniques are the foremost(More)
Imaging techniques are used to create images of structure, function and pathology of human body organs for cancer diagnosis. Various imaging techniques like X-ray, Positron Emission Tomography (PET), Ultrasound (US), MRI etc. are used for cancer diagnosis. These imaging techniques have gone through Lot of advancements during last few years. These techniques(More)
Image processing is processing of images using mathematical operations by using any form of signal processing for which the input is an image such as a photograph or video frame and the output may be either an image or a set of some parameters related to the image. Images quality is often degraded by noises. Noise can occur during image capture,(More)
