Digital Image Integrity
The integrity of a digital image is paramount in fields such as forensics, medical imaging, and military and industrial photography. Courts make decisions affecting an individual’s liberty based, in part, on images presented as evidence. Physicians and researchers make diagnoses based on imaging—holding people’s lives in the balance. Military photographs may determine target locations based on ...
متن کاملMedical Image Integrity Control Combining Digital Signature and Lossless Watermarking
Enforcing protection of medical content becomes a major issue of computer security. Since medical contents are more and more widely distributed, it is necessary to develop security mechanism to guarantee their confidentiality, integrity and traceability in an autonomous way. In this context, watermarking has been recently proposed as a complementary mechanism for medical data protection. In thi...
متن کاملImage quality enhancement in digital panoramic radiograph
One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...
متن کاملA Robust Digital Image Watermarking Scheme Based on DWT
In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...
متن کاملRigour and grounded theory research.
BACKGROUND Grounded theory methodology is a suitable qualitative research approach for clinical inquiry into nursing practice, leading to theory development in nursing. Given the variations in, and subjectivity attached to, the manner in which qualitative research is carried out, it is important for researchers to explain the process of how a theory about a nursing phenomenon was generated. Sim...
