Abstract: A method, system and computer readable media for real-time chromakey matting using image statistics. To identify the chroma key spectrum, the system/method executes in three stages. In an off-line training stage, the system performs semi-automatic calibration of the chroma key parameterization. In the real-time classification stage, the system estimates the alpha matte on a GPU. Finally, an optional error minimization stage improves the estimated matte, accounting for misclassifications and signal noise. Given the resulting matte, standard alpha blending composites the virtual scene with the video feed to create the illusion that both worlds coexist.

Abstract: A method for assigning background pixels an appropriate color to fill all remaining background pixels by a computer after standard paint and overscan techniques to prevent and reduce artifacts. The method includes computing an initial mipmap level and keeping track of which pixels are background pixels. Four pixels at a subsequent mipmap level correspond to a single pixel at a higher level. If the four pixels at the lower level are background pixels, then the single pixel is also a background pixel and a corresponding color is used. Otherwise, the color of the single pixel is the average of non-background pixels.

Abstract: Embodiments of the present invention blend frames over a specified spatial and temporal extent to produce a smoothly animated appearance at a reduced frame rate.

Spatial averaging is used in conjunction with temporal averaging to reduce the rate at which images, including desktop images, are composed and to reduce the amount of graphics memory bandwidth needed for the composition.

Abstract: A de-interlacing methodology generates frames from interlaced video signals by incorporating data from multiple fields into an interpolation-based de-interlacing process. Pixels directly above and below a blank pixel location and pixels immediately before and after the blank pixel location (in the fields immediately preceding and following, respectively, the blank pixel field) can be used to interpolate a pixel value for the blank pixel location. The use of pixel data from multiple fields improves the resolution of the interpolation process, thereby improving output frame accuracy. Adjacent pixel values can also be adjusted to further improve the consistency of the visual display provided by the output frames.

Then, a moving average processing is executed by using only some reference pixels j of which the absolute value of the difference between each of their output levels and the output level of the notable pixel i is smaller than a threshold value.

Abstract: Methods, systems, and computer readable media use closed contours of a modeled surface for various purposes such as displaying a contour map of the modeled surface or computing volumetrics. For the closed contours, a colorfilled contour map may be displayed where each contour level is represented as a shape that has an opaque fill color by calculating the area of each shape and displaying the shapes in decreasing order of area. Where both elevations and depressions are present, such that elevations have a positive area and depressions have a negative area, the shapes are displayed in decreasing order of the absolute value of area. Where null values in the modeled surface are present such that unclosed contours result, values are substituted into the null values to close the contours. These closed contours may then be used for various purposes, such as calculating volumetrics of the modeled surface or generating the colorfilled contour map display according to the area of the closed contours.

In this method, the weighted-averaging is performed after the number of pixels are reduced by the simple-averaging, and this can obtain the reduced image of high quality without overloading the software and hardware. In addition, the edging can be easily performed at the same time as the weighted-averaging.
