Patent number: 8804122Abstract: A method for determining a surface profile of subject's skin includes illuminating the subject with light from a plurality of light sources. The plurality of light sources having distinct colors is configured to illuminate the subject from distinct locations. A multi-color image of the subject is obtained. The multi-color image includes respective values corresponding to respective intensities of light of respective colors for each region of the subject. A surface profile of the subject is determined in accordance with the respective values corresponding to the respective intensities of light of the respective colors.Type: GrantFiled: September 22, 2011Date of Patent: August 12, 2014Assignee: Brightex Bio-Photonics LLCInventors: Rajeshwar Chhibber, Ashutosh Chhibbar, Shefali Sharma

Patent number: 8705815Abstract: Systems and methods are provided for automatic identification of a person based on an analysis of the person's skin. In one embodiment, a method for automatically identifying a person comprises acquiring white-light and UV images of a portion of the person's skin, generating a skin mask from the white-light image, and comparing the skin mask with a pre-stored skin mask of the person. If a substantial match is not found between the two skin masks, the person is not identified, and an error message such as “wrong person” or “person unknown” is returned. Otherwise, the method proceeds to obtain results associated with certain skin conditions using at least the UV image. The results are compared with pre-stored results to determine if the person is the right person or the wrong person.Type: GrantFiled: March 5, 2012Date of Patent: April 22, 2014Assignee: Brightex Bio-Photonics LLCInventors: Rajeshwar Chhibber, Ashutosh Chhibber, Shefali Sharma
