Detection and Recognition of Face in Real-Time

Face detection is process of detecting face in a digital image with the help of some facial characteristics of face. Face detection is a complex process for computer vision field. There are many factors like illumination variations, different type of face expressions, several environmental factors that could impact the face detection. The suggested methodology is based on extracting features from the input image. For feature extraction system applies Haar features. Each Haar feature is created to identify distinct facial characteristics. First of all we have to find best threshold a value from the training set for each feature to determine whether corresponding feature is present or not in the input image. Selected Haar features ought to have a low error rate and be clear. Each Haar feature’s input image goes through before being scanned to produce a single value that will be compare with threshold value.
