omr

omr is a simple python2 optical mark recognition script. It takes as input an image of an answered answer sheet and outputs which alternatives were marked. Scroll down for an example.

Usage

$ python2 omr.py --help
usage: omr.py [-h] --input INPUT [--output OUTPUT] [--show]

optional arguments:
-h, --help       show this help message and exit
--input INPUT    Input image filename
--output OUTPUT  Output image filename
--show           Displays annotated image

Example

$ python omr.py --input img/answered-sheet-photo.jpg  --output /tmp/results.png --show

Q1: A
Q2: C
Q3: C
Q4: E
Q5: N/A
Q6: N/A
Q7: A
Q8: N/A
Q9: N/A
Q10: N/A

In this case, we used the following image as input:

And got the following output:

electron-quick-start

Clone and run for a quick way to see Electron in action.

This is a minimal Electron application based on the Quick Start Guide within the Electron documentation.

Use this app along with the Electron API Demos app for API code examples to help you get started.

A basic Electron application needs just these files:

package.json - Points to the app's main file and lists its details and dependencies.
main.js - Starts the app and creates a browser window to render HTML. This is the app's main process.
index.html - A web page to render. This is the app's renderer process.

You can learn more about each of these components within the Quick Start Guide.
