    摘要： Detecting facial landmarks in a face detected in an image may be performed by first cropping a face rectangle region of the detected face in the image and generating an integral image based at least in part on the face rectangle region. Next, a cascade classifier may be executed for each facial landmark of the face rectangle region to produce one response image for each facial landmark based at least in part on the integral image. A plurality of Active Shape Model (ASM) initializations may be set up. ASM searching may be performed for each of the ASM initializations based at least in part on the response images, each ASM search resulting in a search result having a cost. Finally, a search result of the ASM searches having a lowest cost function may be selected, the selected search result indicating locations of the facial landmarks in the image.

    摘要： A naked-eye 3D TV wall is disclosed, which is composed of a full-color light-emitting diode (LED) display array and a slit grating (or a cylinder lens grating). The grating is placed in front of and parallel to the array, and a distance is made between the grating and the array. The grating direction of the array is provided as an oblique angle. A red, green and blue color LED tube are packed into one tube to make a full-color LED tube to emit full-color light, and the full-color LED tube is the element unit of the array. When a multi-view image is interlaced and displayed on the array, the resolution loss is shared in the horizontal and vertical directions. A 3D image will be watched on the wall without wearing special glasses.

    摘要： Techniques are disclosed that involve face detection. For instance, face detection tasks may be decomposed into sets of one or more sub-tasks. In turn the sub-tasks of the sets may be allocated across multiple image frames. This allocation may be based on a resource budget. In addition, face tracking tasks may be performed.

    摘要： Examples of systems and methods for transmitting facial motion data and animating an avatar are generally described herein. A system may include an image capture device to capture a series of images of a face, a facial recognition module to compute facial motion data for each of the images in the series of images, and a communication module to transmit the facial motion data to an animation device, wherein the animation device is to use the facial motion data to animate an avatar on the animation device.

    摘要： A mechanism is described for facilitating efficient free in-plane rotation landmark tracking of images on computing devices according to one embodiment. A method of embodiments, as described herein, includes detecting a first frame having a first image and a second frame having a second image, where the second image is rotated to a position away from the first image. The method may further include assigning a first parameter line and a second parameter line to the second image based on landmark positions associated with the first and second images, detecting a rotation angle between the first parameter line and the second parameter line, and rotating the second image back and forth within a distance associated with the rotation angle to verify positions of the first and second images.
