I recently discovered by chance that some of my category patterns
have been assigned to really many items, without any more "sub-specification".
(For example "cartoon" + "politics").
So it would be very helpful if XnViewMP would support in identifying
those patterns so one has the chance to find a "seperation category" for them.
An improvement of the Special item "Uncategorized" (= pattern "all none").
It should be not too difficult to identify the patterns:
A row for every item.
The columns are of all existing categories.
Sort (stable!) the list from column 1 to last.
Count the occurences of the category patterns.
Show the top 10.
If the users clicks on top6:
in the category filter pane the corresponding categorys are bold
and the assigned items are shown.
Cool?

Re: Special Items: Top10 assigned category patterns
2 years later...
I corrected an error in the description of the algorithm above,
so it may be better understandable.
("A row for every item")
Also I recently realized the "algorithm" by myself (in C++).
The field it is operating in is the rows (= objects)
and the columns (categories). Bit-wise entry for every category.
Determing the max values takes less than a second
for 1e6 objects, 1e3 categories, 50% assigments.
With SQLite it might be realized similar (I don't know).
Pierre, I could send you the c++ code if you like.
But I have the impression my suggestion for improvement
have to be explained?

Hello,
Thanks for suggesting !
I personnally don't understand what is the issue and the suggestion... But I am absolutly not in the developper team !!
