The constraints are the number of characters, variable kerning, and any spacing or line break decisions made by the word processing software. Use of a variable-width font massively prunes the search space, since far fewer strings will match redaction box length pixel-perfectly. Suggesting matching solutions requires a forward model of the string to pixel transformation, and a probabilistic model assigning probabilities to redacted strings. The forward model requires domain knowledge…</p><p>3 points; 0 discussion replies on HN. <a href="https://hackerpaper.kaipfister.de/p/2206.02285/">Paper and source history</a>.
