Implement a frame selection method for crispier/better models #14

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

Experiments show, that intelligent selection of the frames (use only the
frames with high energy) to build the model increases the quality of the
similarity models.

Implement this technique!

I just talked to a colleague of mine who experimented with the frame selection
method. Implementing it will be easy. Just drop 50% of the silent frames (Sort 
all
frames by power, drop the 50% silent ones). I guess that should be done in
libmirageaudio.

An initial version is in the svn. I still need to write a test-tool to ensure
everything is working as expected. So I'm not closing this issue yet.

The test tool would take a Genre-labeled music collection and do an automatic
genre-classification.

I guess this change means that the similarity models should be re-computed ?
If yes, I'll update MirageDbMigrator for that.

The models are compatible, but the newer ones should be slightly better. I'm 
still
writing a test program to test if the new mirage models work as expected.

I've run a Genre Classification Test, and on my small collection (100pcs) 
everything
looks fine/normal. (Mirage/Test.cs)

So everything should be in place and working. I'm closing this bug.
