Each possible face candidates are normalized to reduce lightning effect caused due to uneven illumination and the shirring effect due to head movement. Then the genetic algorithm is used to generate all the possible face regions which include the eyebrows, the iris, the nostril and the mouth corners.
A reliable face-detection approach based on the genetic algorithm and the eigen-face technique: Firstly, the possible human eye regions are detected by testing all the valley regions in the gray-level image. Any facial feature changes in the database will invalidate the matching process. Image matches with the image stores in database. It is analogous to image detection in which the image of a person is matched bit by bit. Face-detection algorithms focus on the detection of frontal human faces. Examples include upper torsos, pedestrians, and cars. In object-class detection, the task is to find the locations and sizes of all objects in an image that belong to a given class. Face detection can be regarded as a specific case of object-class detection. Face detection also refers to the psychological process by which humans locate and attend to faces in a visual scene. The main elements of this technology are as follows: a) Face Detection b) Face Recognition a) Face Detection: Face detection is a computer technology being used in a variety of applications that identifies human faces in digital images. This system uses Haar cascade algorithm based on viola and jones algorithm for detecting and recognizing the faces. So, why not shift to an automated attendance system which works on face recognition technique? Be it a class room or entry gates it will mark the attendance of the students, professors, employees, etc. Also, for professors or employees at institutes or organizations the biometric system serves one at a time. This process is quite hectic and time consuming. students and this sheet further go to the admin department with updates the final excel sheet.
The current method that colleges use is that the professor passes a sheet or make roll calls and mark the attendance of the students and this sheet further goes to the admin department with updates the final excel sheet. Most of the institutes and organizations follow the manual method using old paper and file method and some of them have shifted to biometric technique. In many Institution and Organization, the attendance is a very important factor to maintain the record of lectures, salary and work hours etc.
