摘要： Methods and apparatus for soft edge masking. A soft edge masking technique may be provided via which, starting from an initial, potentially very rough and approximate border selection mask, the user may selectively apply brush strokes to areas of an image to selectively improve the border region of the mask, thus providing softness details in border regions which contain soft objects such as hair and fur. A stroke may be an additive stroke indicating a particular region in which detail from an original image is to be added to a composite image, or a subtractive stroke indicating a particular region in which detail is to be removed from the composite image. The stroke may also indicate a strength parameter value that may be used to indicate an amount of bias to be used in opacity calculations for the affected pixels.

摘要： A system and method of creating interactive visual content in which base visual content, a selection of a trigger event associated with the base visual content, and intermediate visual content are received as an input. Viewing visual content derived from the base visual content is automatically generated. The viewing visual content can be displayed by a viewing application executing on a computer. A set of regions of the interactive visual content in which swap visual content is to be displayed by the viewing application when the trigger event occurs is automatically generated. For example, regions of the viewing visual content that are to be replace by the swap visual content when the trigger event occurs can be identified. Also, the swap visual content is automatically generated from the intermediate visual content. In addition, instructions operable to cause the computer executing the viewing application to display the swap visual content in the identified regions when the trigger event occurs is automatically generated. Moreover, the intermediate visual content can be received by providing a user interface enabling a designer to edit the intermediate visual content as an integral unit.

摘要： Various embodiments of methods and apparatus for removing unwanted background color from a border region surrounding a foreground object in an image in order to composite the foreground object of the image with a new background image are described. Embodiments of color decontamination for image compositing may accept an image and an alpha matte corresponding to the image as input. In some embodiments, estimated foreground colors are determined for pixels in a border region between the foreground and the background of the input image. In some embodiments, the input image may be created by down-sampling a higher resolution image and pixels with estimated foreground colors may be up-sampled. In some embodiments, a composite image may be created based on the input image, the alpha matte, the estimated foreground colors of pixels in the border region and a new background image. In some embodiments, a texture preserving luminance blending operation may be performed using the estimated foreground colors for pixels in the border region to create refined foreground colors for pixels in the border region. In some embodiments, a composite image may be created further based on the refined foreground colors for pixels in the border region. In some embodiments, parameters controlling the creation of a composite image may be set in response to user input.
摘要翻译：描述了用于从图像中的前景对象周围的边界区域去除不想要的背景颜色以便将图像的前景对象与新的背景图像合成的方法和装置的各种实施例。用于图像合成的颜色去污的实施例可以接受与图像相对应的图像和α遮罩作为输入。在一些实施例中，为输入图像的前景和背景之间的边界区域中的像素确定估计的前景颜色。在一些实施例中，可以通过对较高分辨率图像进行下采样来创建输入图像，并且可以对具有估计的前景颜色的像素进行上采样。在一些实施例中，可以基于输入图像，阿尔法无光泽，边界区域中的像素的估计前景颜色和新的背景图像来创建合成图像。在一些实施例中，可以使用边界区域中的像素的估计前景颜色来执行保持亮度混合操作的纹理，以创建边界区域中的像素的精细前景颜色。在一些实施例中，可以基于边界区域中的像素的精细前景颜色进一步创建合成图像。在一些实施例中，可以响应于用户输入来设置控制合成图像的创建的参数。
