METHODS OF SIFTING OUT SIGNIFICANT VISUAL PATTERNS FROM VISUAL DATA

摘要

An embodiment of the invention provides a method performed by an electronic device. Under the method, the electronic device first analyzes significance-indication information of an image block of visual data to determine whether the image block encompasses a significant visual pattern. The significance-indication information includes the image block's time domain information and/or color domain information. Then, if the electronic device determines that the image block encompasses the significant visual pattern, it sifts the image block out from the visual data.
