FACE DETECTION BASED ON PCA-LDA

摘要

PURPOSE: A method and a device for detecting a face are provided to precisely detect a face area by using a PCA(Principle Component Analysis) and an LDA(Linear Discriminant Analysis) representing a complex pattern of the face to a few main component values. CONSTITUTION: A preprocessor(602) preprocesses an image inputted from a camera(601). An image size changer(603) changes the size of the preprocessed image. A PCA-LDA converter(604) performs the PCA-LDA conversion for each image. A template matching engine(605) detects the most similar target area by matching the PCA-LDA converted image with a template. A template storage(606) stores the template previously prepared from the template matching. An image size adjuster(607) adjusts the size of the image area extracted as a template matching result.
