Digital Imaging Technology

This invited paper will address several emerging technologies that have an impact on scientists moving into digital imaging technology and raise a few concerns about this digital technology that may not have reached our group.The quality of inkjet printers has moved forward at a staggering rate. The latest printers from Epson (the 900 series) have achieved a milestone in image quality that is very significant and yet is difficult to find in the specification sheet. The “dots” which the company claims can be as small as 3 picoliters are sufficiently small that they cannot be seen with the naked eye. with an improved algorithm, the image quality in 1440 × 720 mode is as good as any dye-sublimation printer. The current 980 when printing in 1440 mode prints at twice the speed as the older 900. At only $250, it actually becomes cost effective to replace 900's with 980's solely based on the amount of time that is saved (even at a University).

In Virtue Of

In this chapter, I examine one sense in which digital images are digital; namely, in virtue of being made and presented with digital technology. I begin by outlining some general theoretical commitments regarding the nature and conditions of appreciation. Broadly speaking, the appreciation of art is to be understood in terms of the differential exercise of cognitive skills. Such skills can be exercised when an appreciator takes into account the distinctively digital technology involved in both the production and the screening of digital images. I give some important background on the functioning of computers and digital display tools. This background helps us understand the debate surrounding potential aesthetic losses and gains when working creatively with digital, as opposed to analog, tools.

Complete Process

The process of digital imaging in microscopy is a series of operations, each contributing to the quality of the final image that is displayed on the computer monitor. The operations include sample preparation and staining by histology, optical image formation by the microscope, digital image sampling by the camera sensor, postprocessing and compression, transmission across the network and display on the monitor. There is an extensive literature about digital imaging and each step of the process is fairly well understood. However, the complete process is very hard to standardize or even to understand fully. The important concepts for pathology imaging standards are: (1) systems should be able to share image files, (2) the standards should allow the transmission of information on baseline colours and recommended display parameters, (3) the images should be useful to the pathologist, not necessarily better or worse than direct examination of a slide under the microscope, (4) a mechanism to evaluate image quality objectively should be present, (5) a mechanism to adjust and correct the minor errors of tissue processing should be developed, (6) a public organization should support pathologists in the development of standards.

AbstractIn this work, we developed a method to handle the image quality test-tool precisely. This test-tool is important to evaluate the quality of the medical images for pre-treatment planning phase. But the achieved images are estimated by naked eyes, which does not provide the precise result. Our main goal is to get the desired image parameters numerically. This numerical estimation overcomes the limitation of naked eye observation. Hence, it enhances the pre-treatment planning. The ETR-1 test-tool is considered here. The contrast, the low contrast details and line-pairs (lp/mm) were estimated.

Project Report

The goal of this project report, sponsored by The National Endowment for the Humanities, Division of Preservation and Access, is “to offer some guidance to libraries, archives, and museums in their efforts to convert photographic collections to digital form.” To date, there are no standards for measuring the quality of digital images created from photographs. Therefore, this report is primarily concerned with developing tools to measure image quality. Other technical and managerial issues related to digital imaging projects in general are also addressed.
