摘要： A camera and method which selectively applies image content adjustments to elements contained in the image material. By way of example, the method involves registration of user touch screen input and determination of the arbitrary extent of a specific element in the captured image material at the location at which touch input was registered. Once selected, the element can be highlighted on the display, and additional user input may be optionally input to control what type of adjustment is to be applied. Then the element within the captured image material is processed to apply automatic, or user-selected, adjustments to the content of said element in relation to the remainder of the captured image. The adjustments to the image element may comprise any conventional forms of image editing, such as saturation, white balance, exposure, sizing, noise reduction, sharpening, blurring, deleting and so forth.

摘要： A three-dimensional (3D) acquisition and visualization system for personal electronic devices comprises two digital cameras which function in a variety of ways. The two digital cameras acquire 3D data which is then displayed on an auto-stereoscopic display. For clarity and ease of use, the two digital cameras also function as eye-tracking devices helping to project the proper image at the correct angle to the user. The two digital cameras also function to aid in autofocusing at the correct depth. Each personal electronic device is also able to store, transmit and display the acquired 3D data.

摘要： A system, method, and computer-readable medium for detecting and eliminating correspondence errors associated with image occlusions. In a first embodiment of the invention, the method applies traditional correspondence methods for matching points in two images, a left image (FIG. 1A) and a right image (FIG. 1B), taken of the same scene. The method applies the correspondence method to locate a matching a point (310) in the right image (FIG. 1B) with a “best match” point (320) in the left image (FIG. 1A). A set of matching points (310, 320) is generated. A second search is then performed by using the best match point (320) in the right image (FIG. 1B) as the basis for an additional correspondence search in the left image (FIG. 1A). The range of match candidates in the second search is such that points to the left of the starting point (310) are not tested as match candidates. The point (330) generated in the second search may be the same point (310) that was used in the first search or may be a different point altogether. The results of the second search are selected as the match candidates.

摘要： A radiographic imaging system (100) comprises an X-ray tube (110), a sensor plate (120), and a graphics engine (130). The tube (110) and the sensor plate (120) rotate synchronously about a patient (150) and expose a stereoscopic pair of images which are transmitted to the graphics engine (130). The graphics engine (130) determines (312) the geometry of the system (100). If (314) the pair of images are toed-in relative to each other, the graphics engine (130) converts (316) the images into a parallel geometry. Likewise, the graphics engine (130) also processes (320) the images for keystone distortion, if necessary. Simply flipping the images in the stereo pair distorts the depth of objects in the stereoscopic image. Instead of simply flipping the images, it is desirable to “go behind” the screen (412A) and look at the image from the back. In order to produce a stereoscopic image having this viewpoint, the graphics engine (130) uses the geometry of the radiographic system (100) to adjust (324) the screen parallax of the image after the constituent images are flipped (322) and provide the desired three-dimensional perspective.

摘要： A method (500) adjusts the epipolar lines associated with two or more images (110,120) taken of the same scene such that the images (110,120) are and vertically aligned. The method (500) creates two or more search columns on the first image. The images (110,120) are split into grayscale sub-images corresponding to each color coordinate used to describe the color of a point in the image. A matching algorithm is applied to each point in the search column in each sub-image pair to calculate the vertical shift between the matched points. The shift values calculated for the matched points are then extrapolated across the entire image and used to align the points in the first (110) and second (120) image.

摘要： A system, method, and computer-readable medium for capturing radiographic images and processing the captured images into stereo images. The images are captured using an X-ray imaging system that rotates freely about an anchor point and captures images of the patient or other object from different angles. The images are transmitted to a graphics engine (130) that rotates and adjusts points in the images in order to place them in the same plane and may also combines the two images into a single stereo image. Additional error processing methods are provided in order to reduce resulting distortion.
