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...

In-House Handmade Camera for Indocyanine Green Video Angiography

Background and Aim: Vascular imaging during surgical procedures is very important and has many applications.  There are several methods for intraoperative vascular assessment such as intraoperative angiography, Doppler, and fluorescence-based techniques. The latter group and specially the Indocyanine Green (ICG) Video Angiography (VA) is commonly used for vascular surgery and sentinel node...

Digital Mapping Camera System

Parallel Signal Processing System for a Super High-Resolution Digital Camera

The technology of the digital still camera has recently achieved remarkable progress. The number of pixels in the main stream of consumer-use cameras has reached the 3 million-range, with 5 million the maximum. And for professional-use, the number of pixels has reached the 16 million. Digital still cameras convert signal data generated from these pixel CCD's to luminosity signals and chromatici...

Eye Contact Camera System for VIDEO Conference

We took the face, especially eye or eye gaze, into consideration for discussing the non-verbal interface media. We proposed a method for generating eye-contacted facial images by computer image processing for enforcing and improving the quality of facial, nonverbal communication on the net such as VIDEO Conference. We second proposed a passive eye-camera system based on the facial image process...
