		Microscope image processing is a broad term that covers the use of digital image processing techniques to process, analyze and present images obtained from a microscope.
		Such processing is now commonplace in a number of diverse fields such as medicine, biological research, cancer research, drug testing, metallurgy, etc. A number of manufacturers of microscopes now specifically design in features that allow interface to an image processing system.
		Since most microscopic samples are essentially transparent, and the depth of field of the focused sample is exceptionally narrow, it is possible to capture images "through" a three-dimensional object using 2D equipment.

		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.
		Image brightness (or luminous brightness) is a measure of intensity after the image has been acquired with a digital camera or digitized by an analog-to-digital converter.
		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.

		Each image appears in the window at a maximum size of 320 x 240 pixels by default, regardless of how large the original image is, unless the image size is smaller than the default value.
		When the target image is loaded into the software window, 8 control points appear superimposed on top of the image with three positioned along the left-hand edge, three along the right-hand edge, one in the upper center, and one in the lower center.
		Images will be stored at the same pixel size as the original, regardless of the size utilized in the background subtraction window display.

		Image subtraction is based on the assumption that the background (the cladding and any flaws in the fiber or microfluidic device) will remain constant over the lifetime of the experiment.
		The resolution of the processed image only needs to be good enough to succeed in the final goal of the image analysis, however, which in this case is bud recognition.
		The image is now binary and the moments of each cell are calculated to classify the cell as budding or not budding a daughter cell.

	Molecular Expressions Microscopy Primer: Digital Image Processing - Deconvolution in Optical Microscopy
		Deconvolution is a computationally intensive image processing technique that is being increasingly utilized for improving the contrast and resolution of digital images captured in the microscope.
		The foundations are based upon a suite of methods that are designed to remove or reverse the blurring present in microscope images induced by the limited aperture of the objective.
		Practically any image acquired on a digital fluorescence microscope can be deconvolved, and several new applications are being developed that apply deconvolution techniques to transmitted light images collected under a variety of contrast enhancing strategies.

	Microscope Image Processing
		The same situation obtains to image processing as obtains to all other areas, namely, the most bug free and stable programs are generally the free open source ones that have been in use for several years.
		Microscope images differ from images taken of most other subjects in a very important way, namely, the most important image characteristic is that it provide the best possible display of structures on the original subject.
		Images of slides stained with a single colour dye generally reveal the most detail when the image is recorded monochrome near the wavelength of maximum absorption of the dye.

		Van Leeuwenhoek's microscopes consisted of a single, small, convex lens mounted on a plate with a mechanism to hold the material to be examined (the sample or specimen).
		Compound optical microscopes can magnify an image up to 1000× and are used to study thin specimens as they have a very limited depth of field.
		The stereo microscope is often used to study the surfaces of solid specimens or to carry out close work such as sorting, dissection, microsurgery, watch-making, small circuit board manufacture or inspection, and the like.

		The most common type of microscope, and the first to be invented, is the optical microscope.
		This is an optical instrument containing one or more lenses that produce an enlarged image of the object, and works by refraction (the bending of light).
		Optical microscopes are restricted in their ability to resolve features by a phenomenon called diffraction which, based on the numerical aperture (NA or) of the optical system and the wavelengths of light used (), sets a definite limit () to the optical resolution.

	The Microscope Depot - Digital Camera Adapter Kit FAQs
		Although the adapter may fit on a particular microscope, there may be situations where you have to be extremely careful as the assembly may be unstable or may damage your microscope.
		It is a function of the microscope's projected image size, the lens size of the relay optical system (the Clearshot 600 in the case), the optics built into the camera and the camera's detector size.
		Even if the image you end up with has vignetting, the portion of the picture that contains the microscope's image is going to be so chock-full-of-pixels that you can still get a very high resolution picture.

	Types of Microscopes -- Parts of the Microscope
		Modern microscopes of this kind are usually more complex, with multiple lens components in both objective and eyepiece assemblies.
		Anton van Leeuwenhoek (1632-1723) is generally credited with bringing the microscope to the attention of biologists, even though simple magnifying lenses were already being produced in the 1500's, and the magnifying principle of water-filled glass bowls had been described by the Romans (Seneca).
		They were awkard in use but enabled van Leeuwenhoek to see highly detailed images, mainly because a single lens does not suffer the lens faults that are doubled or even multiplied when using several lenses in combination as in a compound microscope.

	The Paper Project - History of the Microscope
		If however, we are to include the ability to magnify items that are already visible to the naked eye, then we would have to go back to the Egyptians who knew and practiced the art of cutting a polishing stones.
		Based on the letters of William Boreel (the Dutch envoy to the Court of France) the father and son team of Hans and Zacharias Jansen are the inventors of the microscope.
		He made clear the difference between magnification and resolution and criticized the practice of using eye pieces with too high a magnification as "empty magnification." His widely used formula to calculate resolution is based on his wave light theory.

		The need for this technique lies in the fact that image data is a combination of the true image plus factors such as distortions or variations due to the instruments and techniques used to capture the image.
		Then all images are run through deconvolution algorithms to search for and determine any factors that contribute to image distortion..
		Once this is done, any image called up to be viewed or analyzed is corrected using the information derived from the deconvolution analysis of the entire set of images.
