High Quality of Digital Watermarking Images

The most important requirement of watermarking system is the quality of watermarked image. In most applications, the watermarking algorithm must embed the watermark such that this does not affect the quality of the underlying host data. In order to improve the quality of watermarked image of the bit-plane model, the watermark object will be inserted to the selected bit-plane and the other 7 bit...

Image quality in digital radiographic systems.

The aim of the present study was to evaluate the image quality of four direct digital radiographic systems. Radiographs were made of the maxillary central incisor and mandibular left molar regions of a dry skull, and an aluminum step-wedge. The X-ray generator operated at 10 mA. 60 and 70 kVp, and images were acquired with 3, 5, 8, 12, 24 and 48 exposure pulses. Six well-trained observers class...

Scalable edge enhancement with automatic optimization for digital radiographic images

The ability to resolve 2ne picture detail is of paramount importance in medical imaging systems for viewing small tissue, bone structure and anatomy in X-ray images. In this paper, we present a new digital radiographic image processing system with the property of scalability and adaptability. (i) A new automatic optimization algorithm is proposed for display. (ii) An adaptive detection of a reg...

Digital intraoral radiographic quality assurance and control in private practice.

At present, the American Dental Association and the American Academy of Oral Maxillofacial Radiology have guidelines for the dental environment that include quality assurance and control of film-based radiography. Approximately 19%-30% of US dental offices currently use some form of digital intraoral radiography, and growth is expected to continue. It is anticipated that new tools and guideline...
