Visually Lossless Threshold: JPEG 2000 compression of Digital Chest Radiographs

radiologic examination and they account for a large portion of medical image data. For example, 16,110 chest radiographs were performed, resulting in a data volume of 229.9 gigabytes accumulated at the Seoul National University Bundang Hospital in September 2009. Irreversible (“lossy”) image compression appears to be an immediate and effective means to reduce operational costs on transmission a...
