Abstract: One or more implementations access a digital image and determine whether at least one portion of the digital image includes one or more bands having a difference in color. The determination is based on at least two candidate scales. One or more implementations access a digital image and assess at least a portion of the digital image for the existence of one or more bands having a difference in color. The assessing includes determining a fraction of pixels in the portion having a color value offset by an offset value from a color value of a particular pixel in the portion.

Abstract: One or more implementations access a digital image containing one or more bands. Adjacent bands of the one or more bands have a difference in color resulting in a contour between the adjacent bands. The one or more implementations apply an algorithm to at least a portion of the digital image for reducing visibility of a contour. The algorithm is based on a value representing the fraction of pixels in a region of the digital image having a particular color value.

Abstract translation: 一个或多个实现访问包含一个或多个频带的数字图像。 一个或多个频带的相邻频带具有不同的颜色，导致相邻频带之间的轮廓。 所述一个或多个实现将算法应用于数字图像的至少一部分，以减少轮廓的可视性。 该算法基于表示具有特定颜色值的数字图像的区域中的像素的分数的值。
