DIGITAL PROCESSING METHOD OF APPEARANCE EXPRESSION TRANSFORM DATA

摘要

PURPOSE: A digital processing method of an appearance expression transform data is provided to reduce an undesired error in inverse transform data which is generated by a clipping or a rounding by correcting an error at a transform domain after forward transforming data processed at a real domain. CONSTITUTION: In a method of processing transform data for expressing an appearance, the transform data is inverse transformed into a real domain to form high-precis ion numbers(120). The high-precis ion numbers are transformed into an integer, and the integer is clipped to form initial converted data (140). The high-precis ion numbers are operated to generate an effect(310). The appearance is an image, and the affect is a chroma-key merging of two data sets.
