Davis King e3aeab5293 Changed the scan_image_pyramid serialization version number since the 
recent changes make its feature representation incompatible with
previous versions.
 2013-04-02 21:45:46 -04:00
Davis King eca9345fe3 Fixed a bug I just introduced into the scan_image_pyramid. 2013-04-02 21:43:28 -04:00
Davis King c943eb23a2 Added an additional threshold for each detection template. This is useful 
since some detection templates may be larger than others and therefore
naturally accumulate larger scores, therefore necessitating larger threshold
values.

Davis King 5ca5ced275 Fixed a bug which was introduced a few days ago. The problem was that the 
validation routines set the detection threshold to negative infinity in an
attempt to elicit all the possible detections for the purpose of computing mean
average precision scores.  This works fine when using the scan_image_boxes
object but causes the detection quality to degrade when the scan_image_pyramid
is used since this object performs random subsampling to avoid producing an
excessive number of detections.  The fix is to allow the user to set the
adjust_threshold parameter themselves to whatever value they feel is reasonable
rather than hard coding it to negative infinity.

Davis King a1a0e782a1 Upgraded the object_detector so that you can use the adjust_threshold 
argument for all versions of the operator() method.

Davis King f2426231b9 Changed the object_detector interface slightly. In particular, it now handles 
the adjust_threshold argument slightly differently in that it does not add it
to the output detection score anymore.
 2013-03-31 15:18:24 -04:00
Davis King 238effb9c6 Changed average_precision() to use interpolated precision. So now it uses the 
same metric as the one used by the Pascal VOC.

Davis King a924bdad61 Filled out spec for find_candidate_object_locations() 2013-03-24 10:57:40 -04:00
Davis King b638145fb6 Moved the responsibility for automatically filling out a test_box_overlap 
object from the structural_object_detection_trainer to the
structural_svm_object_detection_problem.  This allows us to use image scanners
which require an image be loaded before get_best_matching_rect() can be called.
I also made it so that the scanner loading (and therefore feature extraction)
is threaded.  Previously, it only used a single core.
 2013-03-23 19:49:42 -04:00
Davis King d81641cd8e These templates ostensibly allowed a user to supply their own version of the 
test_box_overlap object.  However, one place in the code assumed the
test_box_overlap object was used and so this feature has actually been broken
for some time.  Moreover, it's probably just confusing and excessively complex
to have this level of user modifiability so I removed the option and hard coded
everything to use the test_box_overlap object.  This makes the code
significantly clearer.
