Davis King 3511853f68 updated a comment 2012-01-01 11:05:38 -05:00
Davis King 88f8a52568 Moved sum_filter() into the file with all the other filtering routines. 2012-01-01 10:50:12 -05:00
Davis King 103073424e Clarified spec 2011-12-31 17:32:29 -05:00
Davis King 828f834dec Made the spatial filtering routines return a rectangle which tells you what 
part of the image wasn't just zero padding along the border.
 2011-12-31 17:07:26 -05:00
Davis King c01d248a3f Added some overloads of shrink_rect() and grow_rect() which 
allow you to adjust the width and height independently.
 2011-12-31 17:03:48 -05:00
Davis King bcf8df16c8 Renamed a test function so it doesn't show up in the ctags list. 2011-12-31 16:40:31 -05:00
Davis King 4bf6655ed6 Added the spatially_filter_image_separable_down() routine which is just a version 
of spatially_filter_image_separable() that does downsampling at the same time
as it does the filtering.
 2011-12-31 16:32:26 -05:00
Davis King ea897b9e54 Made the border_enumerator a little more flexible. Now the border 
doesn't need to be the same size on all sides of a rectangle.
 2011-12-31 16:18:07 -05:00
Davis King 7bd1884154 Fixed bugs in this test 2011-12-31 15:51:55 -05:00

Davis King 3714ff54ce Gave the spatially_filter_image routines the ability to add their 
results to an output image rather than overwrite the contents
of the output image.
 2011-12-30 23:48:23 -05:00

calling get_best_matching_rect().
 2011-12-29 10:28:03 -05:00
Davis King 04626317fb Made this object cache image scanner objects internally rather than 
reconstruct them for each separation oracle call.
 2011-12-29 09:37:27 -05:00

 2011-12-26 12:33:42 -05:00
Davis King 06dc489cc5 Added some more tests and also fixed the existing ones to work 
given the recent changes to the object detection tools.

Davis King c2ad96983c Added the setup_hashed_features() helper routine for configuring 
a scan_image_pyramid when it is used with a hashed_feature_image
and projection_function.
 2011-12-26 12:13:10 -05:00

Davis King 2e98a785bc Removed constness from the operator() member functions of the object_detector 
since they logically modify the state of the object detector now that
we are exposing the state of the underlying image scanner.
 2011-12-26 09:34:24 -05:00
Davis King bf0ed361d7 Refactored code into a cleaner form. 2011-12-26 09:27:31 -05:00

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.
 2011-12-26 00:11:17 -05:00
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.
 2011-12-25 22:46:56 -05:00
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.
 2011-12-25 14:21:37 -05:00
