Abstract: In a method for motion estimation using adaptive patterns in a video sequence compression system, an initial search pattern located at a center of a search window in a block of a video frame is determined. A location of a minimum block distortion measure (BDM) is searched in the initial search pattern. A horizontal search pattern for functioning on the search window is determined in the horizontal direction to search a location of a minimum BDM in the horizontal search pattern. A vertical search pattern for operating on the search window is determined in the vertical direction to search a location of a minimum BDM in the vertical search pattern. The location of the minimum BDM in each pattern is designated to be a motion vector. A search pattern to be used in a subsequent searching stage is determined based on the location of the minimum BDM in each pattern.

Abstract: PURPOSE: A method for detecting a face and an apparatus and a method for detecting an upper body are provided to accurately detect an upper body by combining a face detecting method, an omega area method, and a lateral/rear side detecting method. CONSTITUTION: An omega area detecting part(120) detects an omega area containing a shape composed of a face and shoulder lines from a subject image. A face detecting part(140) detects the face part of a human from the omega area. An upper body verifying part(160) verifies whether the subject image contains the upper body of the human based on the detection result of the face detecting part. Unless the face of the human is detected, a lateral/rear side verifying part(150) verifies the lateral side or the rear side of the human from the omega zone.

Abstract translation: 目的：提供一种用于检测面部的方法和装置以及用于检测上身的方法，以通过组合脸部检测方法，欧姆面积法和侧/侧检测方法来精确地检测上身。 构成：欧米加区域检测部件（120）从对象图像检测包含由脸部和肩部线构成的形状的欧米加区域。 脸部检测部（140）从欧米加区域检测人的脸部。 上身验证部（160）根据人脸检测部的检测结果来验证被摄体图像是否包含人的上身。 除非检测到人的脸部，否则侧/后侧验证部件（150）从欧米加区域验证人的侧面或背面。
