Chain-based framework to split image processing into components.

Project description

cv2studio

cv2studio is an OpenCV framework that give you an ability to decompose processing flow into components.

Features

  • Component-based development
  • Channel independence
  • Classes wrappers for HighGUI elements of OpenCV
  • Channel independence for components

Getting Started

The main principle behind this framework is decomposition. Splitting up a code into one-format components make it highly reusable. It becomes easy to develop different parts of video/image processing separately and share it with others.

Installing

To install the latest release:

pip install cv2studio

Usage

Importing

Before using features of the framework goes importing.

from cv2studio import App, Component

Component creation

To create a component describe a class derived from Component. To use this class it's required to declare the method process(self, img), where img is an image to be process. This function must return an image as well.

class Blur(Component):
    def process(self, img):
        img = cv2.GaussianBlur(img, (5, 5), 5)
        return img

This component apply blur to an input image.

App creation

To create an app that will hold processing components describe a class derived from 'App' and add components using add_component(component) method.

class VideoApp(App):
    def __init__(self, path):
        App.__init__(self, path, VIDEO)
        # self.add_component(MyComponent())
        self.add_component(Blur())

Running

To run the described app use main_loop method. It will start main processing loop with applying chain of added component.

app = VideoApp('path/to/video')
app.main_loop()

main_loop starts a video processing loop. For creating more complex app see the following examples.

Testing

To run tests run the following command:

pytest
