Abstract: A method for tracking an object in a plurality of frames includes obtaining a contour of an object in a frame. For each remaining frame among the plurality of frames, the following steps are performed. A probability map generator generates a plurality of probability maps containing probability values for one or more pixels for a current frame. A contour is estimated for the current frame based on the plurality of probability maps. User input is obtained for refining the estimated contour. Based on the user input, one or more local regions to be added and/or removed are identified and recorded in a local region list. The local region list is maintained and updated during the tracking process and is used together with the probability map generator.

Abstract: Surface asperities, such as roughness characteristics, are reduced or otherwise mitigated via the control of surface regions including the asperities in different regimes. In accordance with various embodiments, the height of both high-frequency and low-frequency surface asperities is reduced by controlling characteristics of a surface region under a first regime to flow material from the surface asperities. A second regime is implemented to reduce a height of high-frequency surface asperities in the surface region by controlling characteristics of the surface region under a second regime to flow material that is predominantly from the high-frequency surface asperities, the controlled characteristics in the second regime being different than the controlled characteristics in the first regime. Such aspects may include, for example, controlling melt pools in each regime via energy pulses, to respectively mitigate/reduce the asperities.

Abstract: Eyewear exhibiting a variable light transmittance functionality is achieved by including a smart lens incorporating an electrochromic (EC) polymer, switchable between a first state and a second state in response to a voltage selectively applied thereto. The smart eyewear includes the smart lens, a voltage source, and a support. The EC polymer transmits more light in the first state than in the second state, because changing the state of the EC polymer varies the light transmittance of the smart lens. The voltage source is configured to provide the voltage required to switch the EC polymer between the first state and the second state, while the support member is configured to support the smart lens and enable a user to wear the smart eyewear. Embodiments can include sensors and controllers to automate the switching, as well as energy harvesting elements to increase battery life.

Abstract: A flexible electrochromic (EC) panel that is usable for a display device or for other applications in which at least a region of the panel is selectively caused to change opacity. An exemplary EC panel includes an electrochromic working layer or electrode formed of a PProDOT-Me2 polymer film that is deposited on an indium tin oxide (ITO)-coated polyethylene terephthalate (PET) flexible substrate. Similarly, a counter electrode is formed by depositing a vanadium oxide-titanium oxide (V2O5—TiO2) composite film on another ITO PET coated flexible substrate. An ultraviolet light-cured film sealant is employed to seal the flexible panel and also serves as a spacer between the working and counter electrodes. The film sealant is patterned to define a volume for injecting an electrolyte solution through an inlet port provided in the film sealant. The inlet port is then closed. The EC panel can readily be flexed without damage.
