We demonstrate two novel editing procedures in the context of fantasy card art. Palette transfer applies a specified reference palette to a given card. For fantasy art, the desired change in palette can be very large, leading to huge changes in the "look" of the art. We demonstrate that a pipeline of vector quantization; matching; and "vector dequantization" (using a diffusion model) produces successful extreme palette transfers. Segment control allows an artist to move one or more image segments, and to optionally specify the desired color of the result. The combination of these two types of edit yields valuable workflows, including: move a segment, then recolor; recolor, then force some segments to take a prescribed color. We demonstrate our methods on the challenging Yu-Gi-Oh card art dataset.

翻译：我们在奇幻卡牌艺术领域展示了两种新颖的编辑流程。调色板迁移可将指定的参考色板应用于给定卡牌。针对奇幻艺术，调色板的预期变化幅度可能极大，导致艺术风格"外观"发生显著改变。我们证明：通过向量量化、匹配与"向量反量化"（采用扩散模型）的流水线，能够实现成功的极端调色板迁移。分段控制功能允许艺术家移动一个或多个图像片段，并可选择性地指定结果所需的颜色。这两种编辑类型的组合产生了有价值的操作流程，包括：移动片段后重新着色；重新着色后强制某些片段采用预设颜色。我们在具有挑战性的《游戏王》卡牌艺术数据集上验证了所提方法。
