	Recommendations and Guidelines for the Use of Digital Image Processing in the Criminal Justice System, Forensic ...
		Digital image processing is an accepted practice in forensic science.
		Image restoration is any process applied to an image that has been degraded by a known cause (e.g., defocus or motion blur) to partially or totally remove the effects of that degradation.
		Image processing does not mean that the input image is overwritten during the process.

	Olympus Microscopy Resource Center: Digital Image Processing Interactive Java Tutorials
		Digital images having higher gray-level resolution are composed with a larger number of gray shades and have a greater dynamic range than those of lower gray-level resolution.
		Image Averaging and Noise Removal - Random noise is a problem that often arises in fluorescence microscopy due to the extremely low light levels experienced with this technique, and its presence can seriously degrade the spatial resolution of a digital image.
		Median Filters for Digital Images - The median filter is an algorithm that is useful for the removal of impulse noise (also known as binary noise), which is manifested in a digital image by corruption of the captured image with bright and dark pixels that appear randomly throughout the spatial distribution.

	Olympus MIC-D: Digital Image Capture and Processing
		The result is often images that are severely degraded and compromised with respect to their potential, based on the power and versatility of the software utilized in the digital processing.
		A lack of sharpness in digital images captured with the microscope often results from poor focus adjustment, vibration, or the specimen not being flat with respect to the imaging plane.
		Zooming to enlarge image details is useful for the visualization of small structures present in a digital image, and scaling is often necessary to format a digital image to fit within the boundaries of a display medium, as in the case of displaying a collection of thumbnail images.

	Ted's Photographics - The Science of Photography - Digital Image Processing
		Digital imaging processes and traditional chemical methods are not mutually exclusive, they can be used together in a wide variety of combinations; and the principles of forming the image by light and lens are the same for chemical and digital processes.
		The image capture process of a digital camera is almost instantaneous as all the sensors are exposed at the same time also the number of pixels is fixed, therefore the image captured has a fixed resolution.
		The response of a digital image sensor to the colour spectrum does not match that of the human eye and filters have to be added, in addition to the colour separation filters, to reduce the sensor’s sensitivity to the near infrared end of the spectrum.

	Image interpretation & analysis - Digital Image Processing
		Digital image processing may involve numerous procedures including formatting and correcting of the data, digital enhancement to facilitate better visual interpretation, or even automated classification of targets and features entirely by computer.
		The objective of the second group of image processing functions grouped under the term of image enhancement, is solely to improve the appearance of the imagery to assist in visual interpretation and analysis.
		Image classification and analysis operations are used to digitally identify and classify pixels in the data.

	Digital image processing - Wikipedia, the free encyclopedia
		Digital image processing is the use of computer algorithms to perform image processing on digital images.
		Digital image processing has the same advantages (over analog image processing) as digital signal processing has (over analog signal processing) — it allows a much wider range of algorithms to be applied to the input data, and can avoid problems such as the build-up of noise and signal distortion during processing.
		Many of the techniques of digital image processing, or digital picture processing as it was often called, were developed in the 1960s at the Jet Propulsion Laboratory, MIT, Bell Labs, University of Maryland, and a few other places, with application to satellite imagery, wirephoto standards conversion, medical imaging, videophone, character recognition, and photo enhancement.

		Image- processing is a technical specialty related to computer graphics and achine vision (Kennie and McLaren, 1988; Friedhoff and Benzon, 1991).
		Digitizing the maps by semiautomated methods at 0.01 inches (0.25 mm) resolution, 3 arc-seconds or about 200 ft (63 m) on the ground, accounted for 1/6 of the approximately two billion elevations.
		Digital shaded-relief maps also lack the distortion inherent in photographs and radar images, and they are free of the clouds, vegetation, and cultural features that mask topographic form on satellite images.

	Final Project: Digital Image Processing
		The particular Landsat TM image which I used for this project was acquired in June; thus, the agricultural fields are almost all still bare.
		Since the image is now in a certain map projection, it should line up perfectly with other projected layers of data, such as political boundaries, land use, soil types, road networks, drainage systems, etc. If the image was collected recently, the information could be used to update outdated GIS layers.
		The characteristics of the TM image I used are summarized at the end of this section.
