چکیده

Advances in solid state technologies have led to a range of CCD cameras from inexpensive video cameras to expensive scientific digital camera systems. The best choice (best value for money) depends heavily on the application. A state-of-the-art camera’s performance is limited by two fundamental laws of nature. Spatial resolution is limited by diffraction and noise is limited by quantum physics. The various noise sources (photon statistics, thermal, readout and quantization) are examined to help you understand some specific operating conditions such as cooling and the choice of readout rates. All CCD based systems can be combined with image intensifiers to boost the sensitivity, to avoid long integration times, or to (de)modulate the detected signal.

Quality comparison of direct digital panoramic radiography and computed radiography panoramic

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

محاسبۀ تابع انتقال مدولاسیون برای بررسی کنترل کیفی در رادیولوژی دیجیتال

The usage of digital radiology systems with insufficient quality control of digital image detectors can efface inherent superiorities of digital systems in comparison with analogue radiology systems and even makes an increased level of patients’ radiation doses. Modulation transfer function (MTF) is one of the most important parameters related to image quality and digital detectors efficiency. ...

Performance Evaluation of Local Detectors in the Presence of Noise for Multi-Sensor Remote Sensing Image Matching

Automatic, efficient, accurate, and stable image matching is one of the most critical issues in remote sensing, photogrammetry, and machine vision. In recent decades, various algorithms have been proposed based on the feature-based framework, which concentrates on detecting and describing local features. Understanding the characteristics of different matching algorithms in various applications ...

Processing Digital Image for Measurement of Crack Dimensions in Concrete

The elements of the concrete structure are most frequently affected by cracking. Crack detection is essential to ensure safety and performance during its service life. Cracks do not have a regular shape, in order to achieve the exact dimensions of the crack; the general mathematical formulae are by no means applicable. The authors have proposed a new method which aims to measure the crack dimen...
