PictMatch

PictMatch is a picture comparator. This
software detects matches (duplicated pictures) across
different folders, by visual similarity (comparing
brightness, hue and saturation pixel by pixel) within a
configurable tolerance) or by exact byte-to-byte comparation
(much faster but less useful).

Crossing folder matches
(pictures in different folders) are also detected.
Duplicated pictures can be deleted, renamed or moved to a
directory. The program can show you the matches, so you can
decide which picture to keep, or the program can take the
actions automatically, based on picture resolutions, size
and contrast. Optionally, the program can create a BAT file
instead of taking the actions instantly. Pictures can also
be grouped by similarity into separated subdirectories making
it easier to organize them later. There is also the
option of generating a report, in four levels of detail,
which can be directed to screen, disk or both. Help file and
tutorial included.
