    摘要： A system and method of the present disclosure provides a region based error diffusion algorithm or function for reducing artifacts in images. The system and method utilizes knowledge of a region of interest (ROI) in an image and applies effects like dithering or error diffusion to the area or region that shows the artifacts, e.g., a banding phenomenon. The system and method provide for defining a region in at least one first image, the defined region having at least one artifact, tracking the defined region to at least one second image, and applying an error diffusion function to the defined region to mask the at least one artifact in the at least one first and second images.

    摘要： A system and method for scaling images are provided. An upscaling algorithm or function is employed that increases the size of an image and then filters the upscaled image to remove aliasing artifacts. The system and method provides for acquiring an image of a first size, detecting the geometry of the image, scaling the image to a second size, and filtering the scaled image with at least one filter based on the detected geometry. During the filtering process, the edges of objects in the upscaled image are detected and different filter frequency responses are provided for the detected edges. Providing different filter frequency responses for the detected edges preserves more details for line images.

    摘要： A system and methods for creating user definable windows for applying image processing, particularly useful in a post-production color correction equipment. The system allows a user of an image processing system such as a scene by scene color corrector to define a color region of interest in an image for purposes of applying image processing only to the region of interest, with automatic tracking of that region of interest over a plurality of frames in a scene. The user defined window, comprising a closed polygon, is converted on a frame-by-frame basis to a matte that is keyed with image processing such as color correction values. The user defined windows can be edited and stored and recalled for use in other frames. The color region of interest is automatically tracked from a beginning frame to the ending frame of a scene, with a vector window defined for each frame, so as to adapt to and compensate for changes in shape, size, and geometry of the region of interest during the succession of frames in the scene.

    摘要： A system and methods for creating user definable windows for applying image processing, particularly useful in a post-production color correction equipment. The luminance values of a key image are captured in a key frame buffer. The key image is edited in a "paint" mode to enhance the luminance values or eliminate regions of the image, to define a region of interest. The key image is then converted to a 1-bit image. The 1-bit image is vectorized to derive a user defined window. The user defined window, comprising a closed polygon, is converted on a frame-by-frame basis to a bit map matte that is keyed with image processing such as color correction values. The user defined windows can be edited and stored and recalled for use in other frames. A user defined window for a first frame of a scene can be transformed or morphed into a user defined window for a final frame of a scene, with the system automatically interpolating between the beginning window and the ending window so that the window is automatically moved, resized, and changed in geometry during the succession of frames in a scene.
