# Whiteboard image color enhancement in Python

Enhance whiteboard images by applying image-processing techniques. Whiteboard image color enhancement is based on this [ImageMagick command line gist](https://gist.github.com/lelandbatey/8677901)

Converted following ImageMagick commands to **Python** and **OpenCV** by applying enhancement functions like

- Difference of Gaussian (DoG)

- Contrast Stretching

- Gamma Correction

```bash

-morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1

```

Run **whiteboard_image_enhance.py** by passing _input_ and _output image path_

```shell

$ python whiteboard_image_enhance.py -i input.jpg -o output.jpg

```

Read how to implement this in my blog [Whiteboard Image Enhancement](https://santhalakshminarayana.github.io/blog/whiteboard-image-enhancement-opencv-python)
