High-fidelity color imaging technology that incorporates spectrum-based color reproduction system, called "natural vision" (NV) is applied to the field experiment of telemedicine. The experiment comprises mainly two parts; 1) High-fidelity color video of open surgery was captured by the six-band multispectral camera, and the image quality was visually(More)
Videos and still-images play quite important role in telemedicine, such as dermatology, teleconsultation, endoscopy, and surgery video. However, one of the problems is the lack of color reproducibility, since it is difficult to reproduce the original color of the object in conventional color imaging systems based on RGB (red, green, blue). Although the(More)
The video capture of surgery is becoming widely used but the colors reproduced by conventional RGB-based video systems differ from the original. In this work, 6-band multispectral video was applied to the open surgery for highfidelity color reproduction, and medical doctors visually evaluated the reproduced image quality. As a result, 1) the 6band video(More)
INTRODUCTION Patients with rheumatoid arthritis (RA) treated with abatacept (ABT) are at increased risk for vaccine-preventable infections. The aim of the present study is to evaluate the humoral response to 23-valent pneumococcal polysaccharide (PPSV23) vaccination in RA patients receiving ABT. METHODS The immunogenicity study was nested within a(More)
The major electronic absorption features in visible region were computationally investigated for a series of novel N-methylmaleimide derivatives. The newly synthesized compounds through the reaction of indolizines with N-methylmaleimides exhibited their maxima ranging 587-634 nm in solution at room temperature. Time dependent density functional theory(More)
We propose finding an optimal generalized color plane to carry out digital color image correlation. We seek the optimization of the correlation peak's sharpness and, for the purpose of analysis, we make some assumptions regarding the statistical properties of images to be considered. The analysis leads to a simple solution involving a projection onto the(More)
