Lip Contour Detection

The term of lip segmentation is really essential concept in many kinds of multimedia systems which also include video conferencing, lip reading, communication systems. It is a very helpful and useful concept in the various kinds of images or video acquisition devices which have encouraged the development of many kinds of computer vision applications such as vision based surveillance along with vision based machine interfaces and vision based biometrics etc.

According to the team of researchers and SEO Jaipur this is the reason that lip becomes a wider field among the technology. An algorithm has been presented by the researchers for the purpose of extraction of lip contour. For this purpose, two algorithms have been used by the researchers in which the first algorithm is based on the colour algorithm that has been derived from the polynomial along with the assumption of the colour of lips that should lie in the range of blue.

The accuracy of the algorithm which has been proposed first by the researchers is 91% in case of normal skin people as well as 95% in the fairer skin colour people. In addition to this, the second algorithm is based on the model based which can give accuracy up to 96%. The concept of the detection of the lip colour is the basic procedure of mouth feature extraction.

It has the ability to form a preliminary stage of face image analysis that is important for numerous application areas which also man machine interaction based on the list of cbse board school in Mansarovar observed human behaviour, video telephony, and face as well as person identification, biomedical speech recognition, face and visual speech synthesis and facial expression classification etc.

According to the team of researchers, all of these applications are requiring an efficient as well as fully automated mouth feature extraction method which can be achieved by using an automatic lip contour detection technique. By observing the pixels in the lips, it has been found by the researchers that lip colour of the fairer skin from dark red to purple as well as for normal skin colour people in its the range of blue normal light conductions.

If we see this from the perspective of the human visual perception by SEO Jaipur, then we will find that lips are very easy in order to be differentiating from the face as well as cause of the several contrasts in colours.
