Digital Image Noise Estimation Using DWT Coefficients
IEEE Transactions on Image Processing, 2021Noise type and strength estimation are important in many image processing applications like denoising, compression, video tracking, etc. There are many existing methods for estimation of the type of noise and its strength in digital images. These methods

The image quality of a radiograph is determined by the local contrast, spatial resolution, latitude and the image noise. The goal of digital processing is to improve the visualisation of pathology by optimising these physical parameters. Processing parameters need to be chosen correctly in order to overcome the inverse relationship between contrast and

Image processing or digital image manipulation is one of the greatest advantages of digital radiography (DR). Preprocessing depends on the modality and corrects for system irregularities such as differential light detection efficiency, dead pixels, or dark noise. Processing is manipulation of the raw data just after acquisition.

Otolaryngologic Clinics of North America, 2002
The digital camera has become a valuable component of the clinical practice for many otolaryngologist head and neck surgeons. Because several technical details distinguish digital cameras from their standard 35-mm counterparts, having some knowledge of these features is crucial for integrating digital imaging successfully into a practice.

Catheterization and Cardiovascular Interventions, 1999
This tutorial introduces basic digital image processing concepts. An increasing fraction of fluoroscopic images are handled and processed using digital tools. The quality of an image in digital format depends on both the technical details of the digitization process and on the quality of the starting scene. Digital tools yield images that are difficult

Applied Optics, 1988
A new technique, digital image velocimetry, is proposed for measurement of instantaneous velocity fields of time dependent flows. A time sequence of single-exposure images of seed particles are captured with a high speed camera, and the sampled images are then digitized on an image processor, enhanced, and superposed to construct a multiple-exposure ...
