Abstract:
Tilt is reduced or eliminated in captured digital images. Edges in a first image are detected. Angles corresponding to the detected edges are determined. A dominant angle is selected from the determined angles. The first image is rotated according to the selected dominant angle to generate a second image. The second image is a de-tilted version of the first image.
Abstract:
The subject disclosure is directed towards controlling the intensity of illumination of a scene or part of a scene, including to conserve illumination power. Quality of depth data in stereo images may be measured with different illumination states; environmental conditions, such as ambient light, natural texture may affect the quality. The illumination intensity may be controllably varied to obtain sufficient quality while conserving power. The control may be directed to one or more regions of interest corresponding to an entire scene or part of a scene.
Abstract:
The subject disclosure is directed towards active depth sensing based upon moving a projector or projector component to project a moving light pattern into a scene. Via the moving light pattern captured over a set of frames, e.g., by a stereo camera system, and estimating light intensity at sub-pixel locations in each stereo frame, higher resolution depth information at a sub-pixel level may be computed than is captured by the native camera resolution.
