2012-04-26	Add harris detector	Benjamin Franzke	2	-1/+235

2012-04-20	hst: Use the middle of a cell for visualization	Benjamin Franzke	1	-3/+3

2012-04-20	hst: Calculate cell position instead of caching	Benjamin Franzke	1	-21/+21
	Its easy to calculate the index from pointer offset, so we can avoid an initialization loop.
2012-04-20	Add hst: Histogramm based SegmenTation	Benjamin Franzke	2	-1/+131

2012-04-19	cvg: Cancel keyboard shortcut if another key is pressed in the meantime	Benjamin Franzke	1	-2/+8

2012-04-18	gauss_cv: Read path to ui-file from argv[0]	Benjamin Franzke	2	-3/+10
	So that gauss_cv doesnt need to be started from its folder.

2012-04-17	Add a very simple vignetting-reduction program	Benjamin Franzke	2	-1/+50

2012-04-05	capture: Use cvQueryFrame	Benjamin Franzke	1	-18/+7
	The splitted cvGrabFrame + cvRetrieveFrame doesnt work as documented anyway. cvGrabFrame _should_ be fast, but does select(2) with a timeout of 2 seconds on the v4l fd.

2012-03-31	roi: Let marked_image always point to a valid pixbuf	Benjamin Franzke	1	-11/+7
	Either by having an own backing storage or by being a reference to the input image.
2012-03-31	roi: Rename input to image	Benjamin Franzke	1	-18/+18

	All those gdk_pixbuf_getters suck

2012-03-31	roi: The configure-event is not yet needed	Benjamin Franzke	1	-8/+0

2012-03-31	roi: Make all functions static	Benjamin Franzke	1	-8/+8

2012-03-31	roi: Schedule rubberband drawing to draw-handler	Benjamin Franzke	1	-79/+68
	So that we get automatic double buffer handling.
2012-03-31	roi: Use gtk_render_{frame,background} for rubberband	Benjamin Franzke	1	-23/+20

2012-03-31	roi: Render only if selected width and height != 0	Benjamin Franzke	1	-1/+3

2012-03-24	wimmel_gl: Use GL_BGRA_EXT in readpixels	Benjamin Franzke	2	-5/+21
	That is the native format graphics cards use, so we reach a fastpath for the copy, which saves around 1s.
2012-03-21	wimmel_gl: Use luminance textures	Benjamin Franzke	2	-28/+33

2012-03-21	commands: Use a smaller scan area	Benjamin Franzke	1	-1/+1
