Abstract: Disclosed is a face verification method and apparatus. The method including analyzing a current frame of a verification image, determining a current frame state score of the verification image indicating whether the current frame is in a state predetermined as being appropriate for verification, determining whether the current frame state score satisfies a predetermined validity condition, and selectively, based on a result of the determining of whether the current frame state score satisfies the predetermined validity condition, extracting a feature from the current frame and performing verification by comparing a determined similarity between the extracted feature and a registered feature to a set verification threshold.

Abstract: A terminal and a method of reproducing a sound source which changes a reproducing attribute of a sound source based on input information and reproduced the changed sound source to provide an effect sound are provided. The method of reproducing a sound source, includes detecting generation of an input; extracting at least one sampling point with respect to the input while the input continues; analyzing input information based on the at least one sampling point; determining a reproducing attribute with respect to a sound source corresponding to the input information based on the input information; and reproducing the sound source corresponding to the input information according to the determined reproducing attribute.
Abstract translation: 提供一种终端和再现声源的方法，该声源基于输入信息改变声源的再现属性并再现改变的声源以提供效果声。 再现声源的方法包括检测输入的产生; 当输入继续时，提取相对于输入的至少一个采样点; 基于所述至少一个采样点分析输入信息; 基于输入信息确定与输入信息相对应的声源的再现属性; 以及根据确定的再现属性再现与输入信息对应的声源。

Abstract: A liveness test method and apparatus is disclosed. The liveness test method includes detecting a face region in an input image for a test target, implementing a first liveness test to determine a first liveness value based on a first image corresponding to the detected face region, implementing a second liveness test to determine a second liveness value based on a second image corresponding to a partial face region of the detected face region, implementing a third liveness test to determine a third liveness value based on an entirety of the input image or a full region of the input image that includes the detected face region and a region beyond the detected face region, and determining a result of the liveness test based on the first liveness value, the second liveness value, and the third liveness value.
