1b5483eef9 templatematch: Produce a warning message if we can't load a template image 2014-07-28 14:18:02 -03:00

88cb33a1dc templatematch: Match rectangle grows redder with increased match certainty
This is useful for debugging your matches as it indicates how certain the
match was in addition to its position.

b608767288 templatematch: Allow changing template property on the fly
Previously changing the template property resulted in an exception
thrown from cvMatchTemplate, because "dist_image" (the intermediate
match-certainty-distribution) was the wrong size (because the
template image size had changed).

Locking has also been added to allow changing the properties (e.g. the
pattern to match) while the pipeline is playing.

 * gst_element_post_message is moved outside of the lock, because it will
   call into arbitrary user code (otherwise, if that user code calls into
   gst_templatematch_set_property on this same thread it would deadlock).

 * gst_template_match_load_template: If we fail to load the new template
   we still unload the previous template, so this element becomes a no-op
   in the pipeline. The alternative would be to keep the previous template;
   I believe unloading the previous template is a better choice, because it
   is consistent with the state this element would be in if it fails to
   load the very first template at start-up.

Thanks to Will Manley for the bulk of this work; any errors are probably
mine.

c77808055d templatematch: Pass video through when nothing to match against
The early return was bypassing the call to gst_pad_push. With no
filter->template (and thus no filter->cvTemplateImage) the rest of this
function is essentially a no-op (except for the call to gst_pad_push).

This (plus the previous commit) allows templatematch to be
enabled/disabled without removing it entirely from the pipeline, by
setting/unsetting the template property.

056d652b92 templatematch: Remove no-op call to gst_templatematch_load_template
We have just set filter->template to NULL, so
gst_templatematch_load_template did nothing.

42a83d2c64 cvvideofilter: Don't try to make buffer writable

e8d569f54d faceblur: set maximum feature size to 0x0
Previously faces would only be detected if they were at least 30x30 pixels
large and at most 32x32 pixels. We keep the minimum setting (maybe needs
a property as in facedetect) but disable the maximum feature size.

b33b1390cc facedetect: set maximum feature size to 0x0
This disables the "max feature size" feature. The current configuration
is totally busted: The max feature size is hard-coded to 2 pixels more
than the user-supplied min feature size which pretty much means you need
to guess the size of the person's face to within a few pixels to get the
code to find it.

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.

6e43f75df3 opencv: fix caps issues and extend supported caps for some elements
Some elements had vague caps, such as "video/x-raw-rgb", which caused problems
at least with textwrite. For other elements, the underlying OpenCV functions
support more than just one image type, so I increased the number of supported
caps.

I created a utility function "gst_opencv_caps_from_cv_image_type", so each
element creates caps directly from OpenCV image types, such as CV_8UC1 for
8-bit grayscale. This function uses gstvideo to create uniform caps.

960ccc118f opencv: define CV_NO_BACKWARD_COMPATIBILITY to suppress warnings caused by compat header
Compile with -DCV_NO_BACKWARD_COMPATIBILITY for now, so that the compat header
doesn't get included, which causes compiler warnings that (it seems) can't be
switched off easily. As a result, we also specify a max. version in configure,
so the build doesn't break if our code doesn't compile against newer opencv
versions any more with that flag.

41b9b76fa5 opencv: avoid 'unused' compiler warnings with inline functions in opencv headers
Override CV_INLINE to avoid 'unused' gcc warnings. GLib will take care of defining
'inline' sufficiently and OpenCV's define isn't good enough to avoid 'unused'
compiler warnings (at least in version 2.1.0).
