Davis King 806c637259 Made this trainer automatically determine decent parameters 
for the test_box_overlap object when it is used and the user
hasn't specifically assigned an overlap tester.

Davis King 9027f84ceb Fixed grammar 2011-12-25 23:14:03 -05:00
Davis King c0d38e4d6d The word "overlap" was used to describe the concept of a rectangle 
matching with a truth rectangle as well as overlap in the context of
non-max suppression of results.  Since these are two very separate
ideas I renamed some things to avoid any confusion.

Davis King 87366f5171 Refactored this object so it uses a hashing function supplied 
by a template argument rather than its own method.  By default,
this object will use the projection_hash.

Davis King cfd0c9941b Added asserts and filled out the spec files. 2011-12-25 13:27:12 -05:00

Davis King 320d56cea8 Added some basic locality sensitive hashing tools. 2011-12-25 11:36:53 -05:00
Davis King 3ebf0f2e3f Refined the scan_image_pyramid interface a little. In particular, I split the 
get_feature_vector() method into two separate functions so the interface
is a little simpler and more flexible.

backwards compatibility with the previous version though.

Davis King dcb8b6ff2a Changed code to avoid compiler warnings. Also added support for the 
difficult, truncated, and occluded metadata fields of the pascal datasets.
 2011-12-15 19:41:07 -05:00
Davis King 0ac4a54094 The object_detector had code in it which limited the number of outputs 
to 100 rectangles.  This has been removed.
 2011-12-15 18:26:29 -05:00
Davis King 7b591aba7a Made assign_image() and assign_image_scaled() capable of assigning to

Davis King b4ba2fce4b Fixed a bug which triggered when using variable length matrices 
as the feature vector type.
 2011-12-11 14:37:57 -05:00
Davis@potato-xp.localnet 560e5a4628 Changed code so it compiles in visual studio 2010 2011-12-11 13:42:32 -05:00
Davis King d89d784a95 Just added a try/catch block around the whole program. 2011-12-10 11:41:43 -05:00
Davis King cbcb80bfd2 Changed the add_probability() method of joint_probability_table so 
it does a saturating add rather than a normal add.  This ensures the
probability value stays exactly <= 1.  Previously, floating point
rounding error could cause it to be slightly above 1 and would therefore
cause some asserts to misfire during debugging mode.
