METHOD AND SYSTEM FOR CLASSIFYING IMAGING DEVICES

摘要

PURPOSE: A method and a system for classifying imaging devices are provided to improve compression efficiency and the video quality by sorting imaging devices from structured page information efficiently. CONSTITUTION: A method for classifying imaging devices includes assigning the imaging device based on the ratio between a perimeter of the imaging device and an occluded perimeter of the Image element, and coding the imaging device according to a coding scheme associated with the category to which the imaging device is classified(150). Exemplary applications include image compression, where categories include image foreground and background layers.
