چکیده

The large amounts of digital image data now becoming available make softcopy imagery exploitation a desirable ca­ pability. One aspect of digital imagery exploitation, image magnification is studied. Two filtering techniques to main^ tain image sharpness as digital images are enlarged are developed. The most promising technique includes the use of a model of the retina of the eye. An example is presented which illustrates the definition of frequency domain filters to satisfy the objective of sharpness maintenance.

A Proposed Simple Teleradiology System Using a Digital Camera

Background & Aims: Teleradiology as an efficient way for avoiding unnecessary transfer of patients to special medical centers requires the images with digital format. However, in some developing countries, including Iran, imaging is being done using non digital devices. In such cases, changing analog images into digital ones can solve the problem. The method which is nowadays used for digita...

Increase in Accuracy of Passive Auto Focusing by a New Sharpness Function

Passive auto-focusing is a key feature in digital cameras and smart-phones which uses the image sharpness function to capture focused images without any user intervention. A focused image is obtained by adjusting the distance between the lens and the image sensor using the sharpness of captured image. This paper introduces a sharpness function for achieving passive auto-focusing in digital came...
