OCEAN Lena

Algorithms for image processing, designed for OCEAN Protocol compute to data (samples).

Requirements

• Python 3.7+

Installation for testing and development

#get repo
git clone git clone https://github.com/calina-c/ocean-lena.git
cd ocean-lena

#set up virtualenv
python -m venv venv
source venv/bin/activate

#install virtualenv dependencies
pip install -r requirements.txt

Local usage

Run any of the algorithms locally e.g. for grayscale:

python grayscale.py local

The result will be saved in output/grayscale.png. The output folder is gitignored.

Running for OCEAN compute-to-data

Assumes "DIDS" is set as an environment variable, input relies in /data/ddos, and output is sent to data/outputs/result):

python grayscale.py
