For the past few days, I’ve been trying to determine — yet again, with new criteria — how much read noise is necessary to properly dither an analog to digital converter of a given precision. Specifically, I’m trying to figure out what the relationship is between dither and quantizing precision when resolving detail is the… [Read More]

Dither and image detail, low contrast
Yesterday and the day before, I wrote a post aimed at discovering the relationship between dither and quantizing precision when resolving detail was the main criterion. The conclusion was that, just as for the avoidance of posterization (see here, here, and here), half a least-significant bit (LSB) was enough noise for most purposes. For critical… [Read More]
