论文摘要
在有限的二维像素化屏幕上多色图像的单一旋转提供了可逆性，组组成，从而提供了信息的保护。旋转已应用于单色图像数据集上，现在我们检查了由于单位转换下的输入图像的离散“不连续性”而近距离出现的吉布斯样振荡。延伸到三色图像，我们在这里检查了像素在振荡下显示颜色的显示，某些像素颜色值可能会超出其所需的常见数值范围[0，1]，在红色，绿色和蓝色强义颜色图像的缺失和饱和之间。
Unitary rotations of polychromatic images on finite two-dimensional pixellated screens provide invertibility, group composition, and thus conservation of information. Rotations have been applied on monochromatic image data sets, where we now examine closer the Gibbs-like oscillations that appear due to discrete "discontinuities" of the input images under unitary transformations. Extended to three-color images we examine here the display of color at the pixels where, due to the oscillations, some pixel color values may fall outside their required common numerical range [0, 1], between absence and saturation of the red, green, and blue formant color images.
