可回放的机器肖像工作室：你观看的绘画就是最终保留的肖像
The Drawing You Watch Is the Portrait You Keep: A Replayable Machine Portrait Studio
AI 导读
研究者构建了一个可回放的机器肖像工作室：用户选择八位虚构艺术家之一并保持静止 8 至 12 秒，随后在 44 秒内观看自己的画像逐步绘出，回放过程不调用模型。在 16 份生成的测试画稿中，每张画稿包含 8,784 至 16,378 个定时触点，约四分之三为固定网格填充，且几乎都短于一帧视频；同一台机器上重复编译同一份画稿四次，输出字节完全一致。

Abstract:Ask an image model for your portrait and a finished picture arrives: no first line, no second thoughts, no record of how it got there, and a different picture if you ask again. I built a portrait studio that works the other way. A sitter chooses one of eight fictional artists, each written with a city, a medium and a tempo of its own, holds still for 8 to 12 seconds, and watches a drawing of themselves appear over 44 seconds. One still is sent after consent, a hosted image model returns a private study the sitter never sees, and a compiler turns that study into one drawing document. The live drawing, the saved sheet, the vector export and the film all read that document, and a replay makes no model call, so the drawing you watch is the portrait you keep. I describe the compiler in enough detail to rebuild it and say plainly what it is: an authored reconstruction at a compressed speed, not a recorded hand. On 16 generated test studies a sheet holds 8,784 to 16,378 timed contacts, about three quarters of them fixed-grid fills and nearly all shorter than one video frame, and recompiling one study gave byte-identical output four times on one machine. The paper also traces a bug that matters more than any of that. The earlier compiler estimated the paper colour tile by tile, read dark skin as paper, and in all eight hands kept less of a deep-complexioned face than a fair one (13 to 48 percent against 41 to 56). On 80 generated studies the rebuilt engine keeps the complexion difference the study already has (raw retention 89 to 120 percent), so the fairness question has moved upstream, to the study and the hosted model. The two test sitters are generated and differ in more than complexion, and no real-face or perceptual study exists yet. The studio is live at this https URL.
