  • Publication number: 20140064604
    Abstract: A method for objectively evaluating quality of a stereo image is provided. The method obtains a cyclopean image of a stereo image formed in the human visual system by simulating a process that the human visual system deals with the stereo image. The cyclopean image includes three areas: an occlusion area, a binocular fusion area and a binocular suppression area. Representing characteristics of the image according to the singular value of the image has a strong stability. According characteristics of different areas of the human visual system while dealing with the cyclopean image, the distortion degree of the cyclopean image corresponding to the testing stereo image is presented by the singular value distance between cyclopean images respectively corresponding to the testing stereo image and the reference stereo image, in such a manner that an overall visual quality of the testing stereo image is finally evaluated.

  • Publication number: 20140054727
    Abstract: A method of forming a transistor is disclosed, in which gate-to-substrate leakage is addressed by forming and maintaining a conformal oxide layer overlying the transistor gate. Using the method disclosed for an n-type device, the conformal oxide layer can be formed as part of the source-drain doping process. Subsequent removal of residual phosphorous dopants from the surface of the oxide layer is accomplished without significant erosion of the oxide layer. The removal step uses a selective deglazing process that employs a hydrolytic reaction, and an acid-base neutralization reaction that includes an ammonium hydroxide component.

  • Publication number: 20140010399
    Abstract: An acoustic system includes a receiver (or microphone), a tube, or a moisture resistant screen. The receiver is capable of outputting an audio signal, while the microphone receives an audio signal. The tube is in connection with the receiver (or microphone) and the audio signal travels along a length of the tube. The moisture resistant screen is fitted at an end of the tube. The moisture resistant screen prevents moisture from passing along the tube toward the receiver, and causes an amount of damping to the audio signal. The moisture resistant screen is configured to have a submersion rating greater than or equal to 7 IP.
