An active pixel masking system for automatic glare suppression uses a variably transmissive screen such as an LCD in front of a lens. A measurement by an image sensor of oversaturated pixels from one or more extremely bright lights is used to generate corresponding opaque pixels in the variably transmissive screen, thereby preventing the excess light from entering the lens, and thereby clarifying the appearance of any objects near to the bright light. A continuous reading of a motion picture image is used to move the location and area of the opaque pixels in response to the motion and area of the light.

Disclosed are systems and methods for providing video content while inhibiting the copying of that content for later viewing. Video images may be made difficult to copy for presentation at later times by the omission or addition of content developed in relation to the particular initial viewing. For instance, video information may be customized by omitting information that is not likely to be substantially perceived by the initial viewer but that is substantially likely to be perceived as missing by at least some other viewers. As another example, video information may be customized for a particular viewing instance so that it contains modified, selected or injected information that is likely to be perceived as non-disruptive or unnoticeable by the original viewer but that would be perceived as substantially noticeable and / or disruptive by some other viewers, including when parts of more than one such video information are combined in an effort to remove customization related to their respective original viewings.

Knowledge of the profile of a road surface—most importantly its defects—is a must to construct an acceptable road surface in this day of high speed traffic. Measurement and calculation of the surface during the process of forming the road—when the road material is still plastic—provides the opportunity to repair unacceptable defects while the road surface material can still be worked. The benefits include a smoother, more durable surface at a lesser cost than methods used on hardened road surfaces. Shown herein is for a method and apparatus for calculating a surface's elevation profile using measurements taken by non-contact devices at a number of locations. Since non-contact sensors are used, elevation profiles of wet concrete can be measured and calculated. Such an apparatus can be mounted on a road paving machine to provide a real time feedback of the surface so corrections to the surface and to the paving machine's operation can be made as required. Alternatively, the method and apparatus can be used just after the pavement is formed but while the pavement is still in a plastic condition so that defects can be corrected before the pavement has hardened.

A method of processing digital source images, each represented by pixel matrices, to obtain from two or more source images, representing one and the same real scene and acquired by utilizing different exposure levels, a final digital image capable of reproducing the real scene with an exposure latitude greater than that of each of the source images.

Thanks to a special filtering to which the weighting coefficients are subjected before the weighted mean operation, the method obtains a final image in which the source images are harmoniously combined with each other.

Medical software tools platform utilizes a surgical display to provide access to specific medical software tools, such as medically-oriented applications or tools, that can assist those in the operating room, such as a surgeon or surgical team, with a surgery. In particular, an optical sensor located within an endoscopic camera may register subtle differences in color characteristics reflected from a tissue surface and in turn transmit the information to a medical image processing system. Moreover, the new tools are intended to help surgeons better determine the boundaries between healthy and diseased regions during surgical procedures. Various tools are intended to be used in procedures where indocyanine green (ICG) fluorescent dye is used.
