ImageStat Flags

Each category of flags contains a specific set of image metrics that can be used with the imagestats and channelstats functions, and the Linter class. The how-to How to customize the metrics for data cleaning shows how to customize the metrics from a flag category.

In addition to the below values, supported group categories are:

ALL_HASHES : XXHASH | PCHASH
ALL_PIXELSTATS : MEAN | STD | VAR | SKEW | KURTOSIS | ENTROPY | PERCENTILES | HISTOGRAM
ALL_PROPERTIES : WIDTH | HEIGHT | SIZE | ASPECT_RATIO | CHANNELS | DEPTH
ALL_VISUALS : BRIGHTNESS | BLURRINESS | MISSING | ZERO
ALL_STATS : ALL_PIXELSTATS | ALL_PROPERTIES | ALL_VISUALS
ALL : ALL_HASHES | ALL_STATS
