The present invention relates to a method, an apparatus and a computer readable recording medium for detecting the location of face feature point using an Adaboost learning algorithm. According to one embodiment of the present invention, a method for detecting the location of a face feature point comprises of: (a) a step of classifying a sub-window image into a first recommended feature point candidate image and a first non-recommended feature point candidate image using the first feature patterns selected by an Adaboost learning algorithm, and generating the first feature point candidate location information of the first recommended feature point candidate image; and (b) a step of re-classifying said sub-window image classified into said first non-recommended feature point candidate image, into a second recommended feature point candidate image and a second non-recommended feature point candidate image using second feature patterns selected by the Adaboost learning algorithm, and generating second feature point candidate location information of the second recommended feature point recommended candidate image, wherein said first feature patterns are determined based on the features of a common face image, and said second feature patterns are determined based on the features of an uncommon face image. |
