摘要： Detection of a facial attribute such as a smile or gender in a human face in an image is performed by embodiments of the present invention in a computationally efficient manner. First, a face in the image is detected to produce a facial image. Facial landmarks are detected in the facial image. The facial image is aligned and normalized based on the detected facial landmarks to produce a normalized facial image. Local features from selected local regions are extracted from the normalized facial image. A facial attribute is predicted in each selected local region by inputting each selected local feature into a weak classifier having a multi-layer perceptron (MLP) structure. Finally, output data is aggregated from each weak classifier component to generate all indication that the facial attribute is detected in the facial image.

摘要： A multi-core processor system may support 3D image rendering on an autostereoscopic display. The 3D image rendering includes pre-processing of depth map and 3D image wrapping tasks. The pre-processing of depth map may include a foreground prior depth image smoothing technique, which may perform a depth gradient detection and a smoothing task. The depth gradient detection task may detect areas with large depth gradient and the smoothing task may transform the large depth gradient into a linearly changing shape using low-strength, low-pass filtering techniques. The 3D image wrapping may include vectorizing the code for 3D image wrapping of row pixels using an efficient single instruction multiple data (SIMD) technique. After vectorizing, an API such as OpenMP may be used to parallelize the 3D image wrapping procedure. The 3D image wrapping using OpenMP may be performed on rows of the 3D image and on images of the multiple view images.
