Nicolas Dufresne	ee940b130f	retinex: Port to GstOpencvVideoFilter base class ... This allow reducing slightly the code. It also fixes a bug caused by in-place buffer being mapped and never unmapped.	2016-12-04 14:49:05 -05:00
Philippe Renon	5594c7e53e	opencv: move base opencv filter class and utilities to gst-libs ... https://bugzilla.gnome.org/show_bug.cgi?id=774223	2016-11-14 18:25:57 +00:00
Luis de Bethencourt	447c1b1395	opencv: clean includes ... The opencv element includes were full of duplicates and uneeded headers. For example a few elements that stopped using gstcvopencvutils still included that header file.	2015-12-12 20:09:15 +00:00
Luis de Bethencourt	45d9184c88	opencv: use gst_opencv_video_filter_set_in_place() ... Using the gst_base_transform function directly won't work. Need to use gst_opencv_video_filter_set_in_place().	2015-09-29 20:00:14 +01:00
Руслан Ижбулатов	589407a077	opencv: Change opencv plugin to use opencv2-style includes ... If old opencv1-style legacy include directory is available, this change becomes purely cosmetic (maybe will compile a bit faster). It becomes an FTBFS fix when opencv1-style include directory is missing (possibly because opencv package maintainer decided not to pack it). https://bugzilla.gnome.org/show_bug.cgi?id=747705	2015-04-17 18:34:22 +02:00
Miguel Casas-Sanchez	407f3e1856	opencv: Add colour image enhancement element based on Retinex algorithm ... Add colour image enhancement element based on Retinex algorithm. Two types exist, namely basic and multiscale; both are described in this article: Rahman, Zia-ur, Daniel J. Jobson, and Glenn A. Woodell. "Multi-scale retinex for color image enhancement." Image Processing, 1996. Proceedings., International Conference on. Vol. 3. IEEE, 1996 Visually speaking the result looks a bit funny, but is pretty invariable to lightning changes, which is good for some applications, like image segmentation. https://bugzilla.gnome.org/show_bug.cgi?id=700977	2013-05-27 11:27:20 +02:00
