Characterized by a plurality of local linear transform function vector extraction method and apparatus and image recognition method and apparatus using the same are disclosed. Local linear way feature vector extraction using a conversion function of (a) class learning image of a second predetermined number of separated into local groups and the average vector of each local group that is separate from the local linear conversion function consisting of a first predetermined number generating and stored in the database; (B) by comparing the input image vector and the average vector of each of the local group assigning the input image to the local group; And (c) a step of extracting a feature vector by the vector projection locally linear transformation function of the local group assigned to the input image. Accordingly, it classified as a local group of the predetermined number of the degree of change is large for a number of data structures having parent dollar tea distribution according to the pose and lighting, obtained by learning the local linear transformation function for each local group, the local linear by extracting a feature vector of the registration image and the recognized image by using the conversion function it can recognize the image to greater accuracy.
