Visual information plays a significant role in face-to-face communication. Clearly, communication between people and machines would be more comfortable if a machine could understand people visually in much the same way as people do. 'OKAO Vision', which stands for face vision in Japanese, is the collection of OMRON's edge-cutting technologies in this area. By visually sensing and extracting useful information from face images, OMRON aims to provide various kinds of services optimized for each individual. These services will match their interfaces and contents to user's capabilities, preferences, condition, attributes, and applicability.

'OKAO Vision" is mainly composed by technologies as follows:

• Face Detection
  Localizing multiple faces in target images quickly and accurately.
  
  
• Facial Features Extraction
  Extracting feature position (e.g. eyebrow, eye, nose, mouth and face contour) in target face exactly.
  
  
• Face Recognition
  Recognizing a person by comparing his/her face with faces registered in database.
  
  
• Facial Attributes Estimation
  Estimating attributes of person such as gender, age and ethnicity with facial image.
