We are only interested in selected few features from the large number of features computed in part I which would enable us to detect the face with great precision. To this, we use the Adaboost Algorithm to pick the key features and to train classifiers that will use them. The purpose of this algorithm is to construct a strong classifier from a linear weak classification combination. Adaboost is an effective boosting algorithm combining simple statistical learners thus significantly reducing both the training error and the more elusive generalization error. A concept called Adaboost which selects the best features and then trains the classifiers which is used. This algorithm creates a sturdy classifier using a linear combination of weighted simple weak classifiers.

FIGURE 2: Flow chart of Cascade Classifier Finally, in the recognition module the fundamental components of the face from the new video are extracted. Then those features get compared with the list of elements stored during training and the ones with the best match is found and name of the person recognized is displayed. This monitoring system fulfills the basic needs of face detection and recognition system, also takes the cost into consideration to ensure the pervasive mode as economical as possible. Furthermore, it can also be combined with real-time analvsis algorithms.

This device is capable of identifying the faces of the image taken from HD Video to analyze and identify the faces. Fron Section IV above, face detection determines where a face is located in an image, and is achieved by scanning the different imag scales and extracting the exact patterns to identify the face. The Prototype is designed from OpenCV with the Haar-Like feature Face detection for hair classifiers is used to create a search window t hat slides through an image and tests whether or not a certail region of an image looks like face. To identify a certain picture as face or non-face, hair-like features and a large set of very weal classifier use one single feature. That function is defined by the prototype and its coordinate relative to the search window that i the origin of the feature's size. The search window scans the first c assifier on the cascade quickly if the classifier returns fals then the calculation on that window also ends and no detected facial (positive) occurs. In addition, if the classifier returns true then the window will be moved in the cascade to the next classifi window return true, the result will also return true for the detection o er to do the exact same thing. When all classifiers for tha f certain window face.

After the face detection step, human-face patches are removed from images via feature extraction phase. If we use these patches for face recognition directly, it may have some limitations; first, each patch usually holds over 1000 pixels, which are too enormous to build a robust recognition. Second, face patches may be taken under different illumination, with different face expressions, and with different camera alignment, and may suffer from occlusion and cluttering background. To overcome these drawbacks, we perform feature extractions to do dimensionality reduction, information packing, salience extraction, and noise cleaning. After this step, we transformed face patch into a vector with fixed dimension or a set of fiducial points and their corresponding locations. We can include feature extraction either in face detection or face recognition as per survey form some literatures.

Simply put, model training is the process of taking several face representation belonging to the same person, and creating a classifier that can recognize more instances of face portrayal from the same person. The most favored approach is to use a linear SVM.

In this step we will use Local Binary Pattern Histogram (LBPH) to consider the face structure and to evaluate patterns. We'll isolate and generalize the details so it can know what face belongs to somebody. FIGURE 7: Training Model

The table above shows the accuracy of the proposed model, and also shows the amount of correct and incorrect face-detected images given as the sample data collection.As, if we have all data models as correctly observed images, we can see it gives the highest precision. Whenever we send the suspected face to the device, it upgrades its data model with the provided face and tries to identify other faces matching the provided face so that it can automatically improve its models leading to correct facial recognition and automated facial identification takes place in live streaming videos or uploaded photographs.
