opencv-proto
https://github.com/idlesign/opencv-proto
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)Read the documentation.
