Abstract: Embodiments described herein are directed to methods and systems for facilitating control of smoothness of transitions between images. In embodiments, a difference of color values of pixels between a foreground image and the background image are identified along a boundary associated with a location at which to paste the foreground image relative to the background image. Thereafter, recursive down sampling of a region of pixels within the boundary by a sampling factor is performed to produce a plurality of down sampled images having color difference indicators associated with each pixel of the down sampled images. Such color difference indicators indicate whether a difference of color value exists for the corresponding pixel. To effectuate a seamless transition, the color difference indicators are normalized in association with each recursively down sampled image.

Abstract translation: 本文描述的实施例涉及用于有助于控制图像之间的转换的平滑度的方法和系统。 在实施例中，沿着与相对于背景图像粘贴前景图像的位置相关联的边界来识别前景图像和背景图像之间的像素的颜色值的差异。 此后，执行边界内像素区域采样因子的递减采样，以产生具有与下采样图像的每个像素相关联的色差指示符的多个下采样图像。 这些色差指示符表示对应的像素是否存在颜色值的差异。 为了实现无缝转换，色差指标与每个递归下采样图像相关联地归一化。
