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)
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)
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 high-fidelity color reproduction, and medical doctors visually evaluated the reproduced image quality. As a result, 1) the 6-band 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)
