Abstract: Techniques are disclosed for performing flood-fill operations on vector artwork. In one embodiment, a region under a point of interest (POI) of vector artwork is rasterized and flood-filled, and an initial bounding shape around that area is used as a first guess as to the area to be filled. In other cases, the initial bounding shape is created around some initial area that includes the POI (no rasterization). In any such case, vector objects having bounding shapes that intersect the initial bounding shape are identified and fed into a planar map. After map planarization, a new bounding shape is created around a new area resulting from the planarizing and that includes the POI. In response to that bounding shape not extending beyond the initial bounding shape, a vector-based flood-fill operation can be performed on that new area. Process repeats if new bounding shape extends beyond previous bounding shape.

Abstract: Visually defining terminology in a paragraph by invoking a multi-media viewer to rotate a subject-object and zoom-in on the associated feature in response to clicking on the terminology; higher resolution, or a different image capture technique is then overlaid. Viewer re-positions near terminology clicked. Clicking on a feature answers a question. Two viewers are synchronized to display the same pose to facilitate a phone conversation; synchronization session is initiated by a pattern of sounds transmitted over the phone. Viewer analytics information is a heat map indicating angles seen, paused, zoomed-in, or terminology clicked; ranks different marketing message wording. After webpage loads, an image having a special pattern within its filename is replaced with multi-media viewer. Upon loading or providing additional subject-object data, advertisements are shown if a subscription fee is not paid. Clipboard data is copied to another computer by a pattern of sounds transmitted over the phone.

Abstract: An originating user captures an original image with mobile equipment. The image is displayed on the originating user's mobile equipment with first annotations. First data information (R1) including the time and the location of the mobile equipment together with information that the first annotations has been displayed is sent to a server. The originating user transmits the image to a second equipment of at least one second user. The image is displayed on the second equipment. Second annotations are displayed to said second user in combination with said image. Second data information (R2) including the time and the location of equipment of the second user together with information that the second annotations has been displayed is sent to the server. The server determines from the location and/or time whether said image is an original image captured by the originating user, or a transmitted image displayed to a second user.

In one embodiment, the distortion information associated with a lens is determined. The distortion information is stored. A captured image taken by that lens is processed, with reference to the distortion information.

Abstract: A system for enhancing an image displayed on a display unit of an aircraft is shown and described. The system includes an enhanced vision system that detects a scene and enhances the scene for display on the display unit. The enhanced vision system includes a sensor having a filter configured to filter out all but at least one narrowband spectrum of light from the scene to detect elements of a first color. The enhanced vision system causes remaining content of the scene to be removed from the filter output for completing the detection of the elements of the first color. The enhanced vision system enhances the elements of the first color on the display unit.

Abstract: A method for removing cyclic noise from a borehole image includes transforming the image into the frequency domain using a two-dimensional (2-D) transform (e.g., using a discrete cosine transform). The cyclic noise components (peaks) are removed from the transformed image which is then inverse transformed back into the spatial domain using an inverse 2-D transform to obtain a corrected image. An automated method enables the cyclic peaks to be identified and removed from the borehole image via downhole processing.
