This branch of camorama has been adapted to try out various computer-vision
filters, starting with a Reichardt motion detection filter.
These filters are added in addition to the ones already in camorama.

----------------------------
camorama - view, alter and save images from a webcam
how to build:
./configure
make
su
make installl
how to run:
camorama (options)
options:
-h usage
-V version info
-D debugging info
-d <video_device> use <video_device> instead of the default (/dev/video0)
-M use maximum capture size (depends on camera)
-m use minimum capture size (depends on camera)
-H use middle capture size (depends on camera)
-x <width> width of capture
-y <height> height of capture
gui:
sliders for various image properties. if something doesn't work, it is not supported by your camera/driver.
buttons turn on various filters
fix colour: bgr->rgb conversion
wacky: started out as an edge detection function, turned into, um, this ;-)
threshold: any pixel with an averave value < x turns black or > x turns white. x is adjustable with the dither slider
channel threshold: same as above, but does it for each channel, red, green and blue.
sobel: didn't turn out right, but i thought this looked cool too :).
edge detect: shoddy laplace edge detection function
negative: makes picture negative
mirror: mirror image
colour: colour or bw
smooth: smooths image
other buttons: capture - capture image - see prefs.
preferences:
general:
- local capture - capture to hard drive
- remote capture - capture and upload via ftp
- automatic capture - capture images automatically
- capture interval - time between captures, in minutes
local capture:
- directory - dir where captures will be saved
- filename - filename for captures
- append time to filename - should camorama append the time to the filename. if not, it will overwrite the last image if it has the same name.
- image type - what to save the image as.
- add timestamp - put a timestamp in the lower left corner of the image (can be customized)
remote capture:
- ftp host - where you want to upload your image
- username - username on ftp server
- password - password on server. this will be stored by gconf, in ~/.gconf/apps/camorama/preferences, so if you are concerned about security, don't use this feature.
- save directory - where to save the file on the server. using the full pathname seems to work better.
- filename - filename for captures
- append time to filename - should camorama append the time to the filename. if not, it will overwrite the last image if it has the same name.
- image type - what to save the image as.
- add timestamp - put a timestamp in the lower left corner of the image (can be customized)
timestamp: you can use the date/time, a custom string, or both together.
- use custom string - use a custom string in the timestamp
- custom string - string you want to use in the timestamp
- draw date/time - add date/time in the timestamp
problems:
- runs slow on quickcam and when the capture size is large - getting much better....
please email me if you have any problems building or running camorama or if you have any comments/questions <greg@fixedgear.org>.
tested cams:
- creative webcam 3
- quickcam express
- 3com homeconnect camera - using the 3comhc driver, not the default kernel driver
requirements:
- a working version of gnome 2 (http://www.gnome.org)
- video for linux (http://www.exploits.org/v4l)

these are projects that i looked at when creating camorama:
- gspy (gspy.sourceforge.net) - gnome/v4l stuff, code for image timestamp
- gqcam - gnome/v4l stuff - the more i work on camorama, the more it becomes gqcam2 ;)
- xawtv - v4l stuff
- metacity-setup (http://plastercast.tzo.com/~plastercast/Projects/) - configure scripts and gnome2 stuff
- Mark McClelland for the code for YUV->RGB conversion
- gnomemeeting for the eggtray icon stuff (system tray applet).
