    摘要: A microlens on the end of an optical fiber has reduced back reflections to a light source, such as a pump laser diode. In a particular embodiment, the microlens is lapped on two radii, at least one of which is offset from the center axis of the fiber, to form a point on the end of the fiber, thus reducing a surface for reflecting light back to the light source. In another embodiment, the microlens is formed with two different side surface angles to accommodate misalignment of the light source to the fiber mount. In another embodiment a Fresnel lens structure on the end of the fiber operates optically as an angled chisel lens.

    摘要: Methods, apparatuses, and computer program products are herein provided for enabling hand gesture recognition using an example infrared (IR) enabled mobile terminal. One example method may include determining a hand region in at least one captured frame using an adaptive omnidirectional edge operator (AOEO). The method may further include determining a threshold for hand region extraction using a recursive binarization scheme. The method may also include determining a hand location using the determined threshold for the extracted hand region in the at least one captured frame. The method may also include determining a fingertip location based on the determined hand location. Similar and related example apparatuses and example computer program products are also provided.

    摘要: A method for providing a mechanism for gesture recognition may include causing down-sampling of image data received to generate down-sampled image blocks for a plurality of image frames, causing extraction of a plurality of features from the down-sampled image blocks, determining a moving status of the down-sampled image blocks based on changes in values of respective features in consecutive frames, and determining a direction of motion of an object in the image data based on movement of a first border and a second border of a projection histogram determined based on the moving status of respective down-sampled image blocks. A corresponding apparatus and computer program product are also provided.
