Face detection consider image analysis and is one of the vital operations for people detection and face matching with existed data. Having enough information from an image is a method which examined in statistical and cognitive recognition which image processing and machine vision are tools of that. Image conception problem is related to have enough information from an image. In this approach, a new method for face detection proposed based on Eigen face as feature extraction and Bat algorithm as classification. This method used for finding people faces as vector in images. The obtained results show that proposed method have high accuracy and speed in comparison to other methods.
