# barcode detection
> detect barcodes in images and draw a border with a custom color around them
```shell
$ python3 barcode-detector.py --path example.tif --color "255:0:255"
```
## Usage
```
usage: barcode-detector.py [-h] -p PATH [-c COLOR]
options:
-h, --help show this help message and exit
-p PATH, --path PATH Path to the input image
-c COLOR, --color COLOR Color of the border, fmt: r:g:b
```
## Inner workings
The barcode detector works by applying several filters to an image and
extracting the contours of the barcodes. If a barcode could not be detected
consider tweaking constants in the source file.
The algorithm is made up of the following filters and stages:
1. sharr gradient in x and y direction
2. subtract y from x gradient for finding barcode region
3. blur and threshold
4. Closing kernel
5. Series of dilations and erosions
6. Largest contour should be the barcode
