What is the face recognition?

Face recognition is a computer technique that uses an algorithm to find and recognize the face in the image, and this technology has several uses. Although many different facial recognition algorithms are available, most programs are used to locate the face. Recognition of the face of images not only finds a face, but most algorithms also show the user's accurate face location in the image, making it easier to find a certain face in a crowded or blurred image. In the entertainment industry, facial recognition is used to watch the face to capture movement that is used for more realistic animation. Another common use of this technique is the safety of face recognition; The algorithm is usually specialized in this case to recognize only certain faces. The edge detection is usual, because it is usually not as reliable as eye detection. When detecting the edge, the algorithm is looking for edges and curves that are common on the human face. Eye detection is looking for eyes even if theyWhich algorithms can be able to recognize them only if the image shows a person to which they look forward to both eyes.

In addition to finding a face, this algorithm of recognition usually shows the exact coordinates of the face pixels. For most users, especially in bright photographs in which the face is easily found, this may not be very important. If users search blurry and crowded images, the accurate placement of pixels may be known to find and identify the person in the figure.

Further use for algorithms of facial recognition is in entertainment, especially when capturing movement and animation of performance. In this technique, actors and actresses act in front of a blue screen while reading their lines. This allows you to capture facial and body movements, making it easier to model movements and increase realism. Actors and actresses wear special electrodes and algorithm recognition on their facesFace follows all facial movements used for expressions. This algorithm is specialized in translating face images in real life into animated images.

Specialized algorithms of facial facial recognition are used in safety systems that depend on the permission of visitors of their faces. Unlike other algorithms that just find the face, these algorithms are programmed to find a certain face. Usually these algorithms must find common elements of a face of a certain person - such as eyes, jaws, ears and cheekbones - and then compare the face with one in their image database. If the faces are the same, then the visitor is awarded access.
