In order to solve the security problems associated with medical information and improve the robustness of watermarking algorithms for medical images, a unique approach to watermarking based on block operations is presented. This study considers the medical images as the cover image, with the watermark logo considered secret information that needs to be protected over the wireless transmission in telemedicine...
Image watermarking is an effective way to secure the ownership of digital photographs. This paper proposes a new methodology for integrating a watermark on the basis of various integrative strengths. The image is separated as 8 × 8 pixels blocks that do not overlap. The pixel size for each image block has been determined. For the embedding areas, picture blocks with the highest value have been chosen...
Breast Cancer is one of the major causes of death among women. Early diagnosis can improve the patient's survival rate. Traditional diagnosis method such as biopsy is not much efficient. However due to the large scale of the medical image data, Inspired by the advanced computing technology which is capable of performing image processing using computer aided diagnosis (CAD) systems to assist clinicians...
Orthogonal frequency Division Multiplexing (OFDM) is an attractive technology in Wireless Communication. High Peak-to-Average Power Ratio (PAPR) is one of the challenging issues in OFDM systems. High PAPR force the High Power Amplifier (HPA) to operate in its linear region with wide dynamic range, where the power efficiency is very poor. The poor power efficiency makes the reduction of PAPR more important...
