Face Image Normalization For Authentication Under Diverse Lighting Conditions, N/A

Defensive Publications Series

Authentication based on face recognition can fail under poor lighting or exposure conditions. This disclosure describes techniques to improve the brightness and/or contrast of a given facial image such that face recognition based authentication can be performed robustly over a wide range of lighting or exposure conditions. Brightness is improved using gamma correction, where the optimal gamma value is given by a low-complexity, closed-form formula. Contrast is improved by subjecting pixel intensities to a mapping that results in better color saturation, or a larger standard deviation of pixel intensities. The techniques work on near infra-red (NIR) as well as visible-spectrum …

Guiding Capture Of New Photos Based On Published Photos, Amy Zhang, Cliff Sze

Defensive Publications Series

This disclosure describes techniques for presenting recommendations that guide users to capture high-quality photos based on existing crowdsourced, popular, and/or shared photos.

Oled With Self Compensation, Hp Inc

Defensive Publications Series

This invention discloses a new structure and approach to detect and compensate OLED nonuniformity

issue, including image sticking. On the TFT backplane, there are driving TFT and sensing

TFT. During OLED light on, while most light goes to top direction to the user, a small amount of light

goes to sensing TFT and be detected. There by comparing the level of the response of each sensing

TFT, system is able to know the luminous difference of each pixel. And then, adjust the appropriate

driving voltage to make the luminous closer. This will minimize the image sticking.

Refining Shopping Search Queries And Results Based On Inferred Product Purchases, Matthew Sharifi, Victor Carbune

Defensive Publications Series

Knowing a user’s purchase history can be helpful in refining, rewriting, or correcting a shopping related search query the user enters since users often purchase products that are related to or same as products bought previously. However, the text input in searches for products is often short, ambiguous, or underspecified. Even in cases where a user includes relevant detail in a query, manual formulation of the search terms, often from memory, can result in errors. Current shopping search mechanisms do not help detect and refine underspecified or erroneous queries. This disclosure describes techniques to improve keyword-based product search by appropriate …

Determining Viewport Area In User Interfaces With Occluding Elements, Anonymous

Defensive Publications Series

This disclosure describes techniques for the determination of occluded and unoccluded spaces within a user interface.

Ambient Light Independent Depth Acquisition Using Switchable Ir Filter, Ping Tong Chu, Chung Chun Wan

Defensive Publications Series

Devices such as smartphones, tablets, etc. are equipped with cameras that have depth-sensing capabilities. The quality of depth acquisition in such devices is often limited by the cost, available physical space for depth-sensing hardware, and by the ambient light conditions in which an image is captured. This disclosure describes a depth-sensing camera system that utilizes a switchable infrared filter. In an IR-cut mode, used when ambient light is of sufficient quality, the filter allows visible light to pass through and cuts off IR. In an IR-pass mode, used in low light conditions, the filter allows IR to pass through while …
