  • Patent number: 10535120
    Abstract: Mechanisms are provided to implement an adversarial network framework. Using an adversarial training technique, an image obfuscation engine operating as a generator in the adversarial network framework is trained to determine a privacy protection layer to be applied by the image obfuscation engine to input image data. The image obfuscation engine applies the determined privacy protection layer to an input image captured by an image capture device to generate obfuscated image data. The obfuscated image data is transmitted to a remotely located image recognition service, via at least one data network, for performance of image recognition operations.

  • Publication number: 20190372055
    Abstract: The present invention discloses a general, highly effective and scalable extraction-enhancing OLED display pixel structure based on embedding the OLED inside a three-dimensional reflective concave structure selectively filled with a high-index filler material. Such a structure is able to couple as much as possible internally generated photons into the filler region and then redirect otherwise confined light for out-coupling via the reflective concave structure. Ultimately high light extraction efficiency approaching ˜80% and excellent viewing characteristics are simultaneously achievable with optimized structures using highly transparent top electrodes. This scheme is scalable and wavelength insensitive, and thus can be generally applied to all red, green, and blue pixel OLEDs in high-resolution full-color displays.
