URL: <http://savannah.gnu.org/bugs/?38179> Summary: cp2tform: 'projective' transform very slow Project: GNU Octave Submitted by: pantxo Submitted on: dim. 27 janv. 2013 22:46:56 GMT Category: Octave Forge Package Severity: 3 - Normal Priority: 5 - Normal Item Group: Performance Status: None Assigned to: None Originator Name: Originator Email: Open/Closed: Open Discussion Lock: Any Release: dev Operating System: Any _______________________________________________________ Details: Due to the use of svd() decomposition, projective transform is slow (N² -> can't accept very larger datasets). Attached is a patch that avoids the use of svd and makes the function run much faster. _______________________________________________________ File Attachments: ------------------------------------------------------- Date: dim. 27 janv. 2013 22:46:56 GMT Name: cp2tf_remsvd.patch Size: 794 o By: pantxo <http://savannah.gnu.org/bugs/download.php?file_id=27333> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?38179> _______________________________________________ Message posté via/par Savannah http://savannah.gnu.org/
