Work in progress. Stay tuned.
Description
Allows fast prototyping in Python for OpenCV
Offers primitives and simplified interfaces to streamline prototypes construction in Python.
Facilitates:
Windows construction and management
Trackbar construction
Configuration save/load (including trackbar values)
Key binding (e.g. for trackbar control, configuration save/load)
Video capturing and modification
Work with images
Work with text
Frames transformation
Samples
Color Palette
Let’s replace 37 lines of source code from Trackbar as the Color Palette tutorial with ocvproto-based implementation:
from ocvproto.toolbox import WindowManager, Canvas
with WindowManager() as wm:
rgb = wm.window.add_trackbar_group(['R', 'G', 'B'], max=255)
for _ in wm.app.loop():
wm.set_frame(Canvas(512, 300, color=rgb))
Camera capture
Now let’s capture video camera stream into ocvproto.avi file, being able to adjust blur.
Let’s also setup config filepath (ocvproto.json) - this allows us to store current trackbar values (s key) and load them (r key). It is useful to restore settings between sessions.
We bind z key to take camera shots.
from ocvproto.toolbox import WindowManager, Camera
with WindowManager() as wm:
wm.app.set_config('ocvproto.json')
blur = wm.window.add_trackbar_group(['x', 'y'], 'Blur', default=1)
with Camera() as cam:
wm.app.bind_key('z', cam.dump_image)
for _ in wm.app.loop():
cam.read()
cam.blur(blur)
cam.dump()
wm.set_frame(cam)
