  • Publication number: 20150195540
    Abstract: System and method embodiments are provided for achieving improved View Synthesis Distortion (VSD) calculation and more accurate distortion estimation of encoded video frames. An embodiment method includes obtaining a depth map value for a video frame and determining a weighting factor for depth distortion in accordance with the depth map value. The weighting factor maps a pixel range of the depth map value to an output function having higher values for closer image objects and lower values for farther image objects. The VSD for the video frame is then calculated as a function of absolute horizontal texture gradients weighted by a depth distortion value and the weighting factor determined in accordance with the depth map value.

  • Patent number: 8461114
    Abstract: Modulating the interaction between ErbB2 and Erbin is an effective method for treating one or more symptoms of ErbB2-mediated disorders. It has been discovered that Erbin stabilizes ErbB2 in vivo and inhibiting the formation of heterodimers between Erbin and ErbB2 reduces or inhibits the biological activity of ErbB2 relative to control levels. Reducing the biological activity of ErbB2 is useful in the treatment of conditions characterized by the overexpression or misregulation of ErbB2. These conditions include, but are not limited to breast cancer and prostate cancer. Alternatively, agonist of Erbin that promote or enhance the interaction of Erbin with ErbB2 can be useful in the treatment of certain neurological disorders. It has also been discovered that Erbin plays a role in the myelination of neurons of the peripheral nervous system.
