AGE GROUP CLASSIFICATION USING FACE FEATURES

ABSTRACT--

 Most of the facial features recognition, say for an example, character, gender and expression has been broadly envisioned. Programmed age assessment and prediction of future expressions have once in a while been examined. With the increase in age of human beings, we can see some gradual changes in their facial features. This paper aims to give a procedure to gauge age gathering that makes use of facial features. This procedure takes account of three stages: 1. Location, 2. Feature Extraction and 3. Classification. The geometric components of face pictures such as face edge, wrinkle topography, left eye to right eye separation, eye to nose separation, eye to jaw separation and eye to lip separation are calculated. By considering the surface and shape data, age grouping is done making use of K-Means bunching calculation. Age features are further ordered progressively based on the gathered data making use of K-Means bunching calculation. The acquired results are pretty vast and efficient. This paper can further be utilized for anticipating future confronts, arranging gender orientation, and expression recognition from images of the various faces.

INTRODUCTION

Facial features of respective faces can be used to identify individuals. The study of features of a face is known as “FACE RECOGNITION”, which is one of the important biometric methods used in the current scenario. As compared to conventional authentication strategies, Biometric methods are considered as highly significant and advantageous, because biometric features are unique individual to individual. This issue of individual verification and identification is a vast area for researchers. Commonly utilized validation strategies involve face, voice, fingerprint, ear, iris and retina and research in those areas are going on from over the last two decades. Conventionally, face recognition is used especially for the resolution of identification in several areas. It is also utilized for identifying several reports like land enrollment, travel papers, driver’s licenses and finding out any person within a security range. Pictures capturing facial features are progressively used for verification in high safety zone applications. As the age of an individual increases it results in the change of facial features, so the database needs to be upgraded as per these changes and to update the database is a challenging task. So our aim is to address the problem of facial ageing and to develop a mechanism that will identify any person with an accuracy of 100%. This paper aims successful age bunch estimation by utilizing facial components such as surface and shape from the image of the persons face.

For efficient results, computation of geometric elements of facial picture like wrinkle geology, face point, left to right eye separation, eye to nose separation, eye to jaw separation and eye to lip separation is performed. For the composition and shape data, classification of age has been done by making use of K- Means clustering algorithm. Age extents are organized progressively based on the gathered data utilizing K- Means clustering algorithm. For quite a long time, human facial image processing is one of the vibrant and intriguing exploration issues. As human faces give a considerable amount of data, numerous themes have drawn heaps of considerations and hence concentrated completely. Majority of them falls under “face recognition” . Few of the research focus on feature faces, remaking faces from some of the suggested features, collaborating the gender orientation, races, and expressions from facial images, and so on. Also, not that many studies have been done on age classification till now. Kwon and Lobo initially started researching on the age classification issue. They talk about the craniofacial research, dramatic cosmetics, plastic surgery, and discernment to find out the actual elements that changes as age increases. They divided grayscale facial pictures to three age groups i.e. babies, young adults and  senior adults. In the beginning, they connected deformable formats [9] and also snakes [7] to find out the essential elements, (like eyes, nose, mouth and so on) from a facial image, and based on that judged if it is a baby or adult by finding out the distance between these components. Initially, they made use of snakes to find out wrinkles on particular areas of the face in order to break down the facial image so as to decide the category like young or old. Known and Lobo declared that their results were promising and efficient. Their information set was having just 47 images, and the results that identified the images as baby was beneath 68%. Moreover, the routines they utilized for this area, i.e. deformable layouts and snakes, are computationally extravagant, but the framework won’t be suitable for ongoing research.
