METHOD AND APPARATUS FOR ADAPTIVE ANALYSIS OF SPEAKING FORM

摘要

A method and an apparatus for analyzing an adaptive speaking screen are provided to determine a speaking screen through screen analysis and update a reference feature value to a feature value and a reference edge feature value by the determined speaking screen, thereby analyzing the speaking screen adaptively according to environment. A method for analyzing an adaptive speaking screen comprises the following steps of: receiving the speaking screen of a speaker from the outside(501); selecting at least one moving region in the received speaking screen of the speaker(503); extracting the contrast ratio distributed value and feature value of the at least one moving region respectively(505); comparing the respectively extracted contrast ratio distributed value and feature value with a preset reference feature value to select at least one moving region having the contrast ratio distributed value and feature value corresponding to the preset reference feature value(507); determining a region, which exists in an upper part as much as a predetermined position in the at least one selected moving region, as a comparison target candidate region(509); selecting a speaking region matching a preset reference screen more than a threshold value out of comparison target candidate regions(511,515); extracting the feature value and contrast ratio of the speaking region(519); and updating the extracted feature value and contrast ratio to the preset reference feature value(521).
