20120140091 | METHOD AND APPARATUS FOR RECOGNIZING A PROTRUSION ON A FACE - A method and apparatus for recognizing a protrusion on a face is proposed. The apparatus forms two images, wherein one is formed in a condition in which a target is lighted and another is formed in a condition in which the target is non-lighted. Face regions are detected from the images respectively and then are compared each other. Then, analyzing change in intensity for indicating change in contrast of the compared regions is performed. Based on the result of the analyzing, it is determined whether there is a protrusion in a face presented in the images. | 06-07-2012 |
20120294535 | FACE DETECTION METHOD AND APPARATUS - Image fragments are formed in regions corresponding to circles searched from an input image. In a cascade of homogeneous classifiers, each classifier classifies input vectors corresponding to the image fragments into a face type and a non-face type. This procedure is performed on all images included in an image pyramid and the coordinates of a face detected based on the results of the procedures on all images. | 11-22-2012 |

20090245294 | Fibre Laser with Intra-cavity Frequency Doubling - The invention disclosed herein relates to fibre lasers with intra-cavity frequency doubling. In one embodiment, the invention is directed to a fibre laser with intra-cavity frequency doubling characterized in that a non-linear crystal of type II phase matching is used to thereby enable operation of the fibre laser without selection of polarisation of the generated fundamental radiation. The non-linear crystal is oriented so as to minimise the walk-off angle of the second harmonic radiation, and a second dichroic mirror together with one of a plurality of focusing elements forms a telescopic reflector that provides for focusing and compensation of the spatial walk-off effect of the non-linear crystal. | 10-01-2009 |
