Detect difference between two images.
By separating each image into few parts, Gazo-san only detects difference on matched parts between two images. Optional shows decrease or increase part on two images.
You can use Gazo-san with docker.
Get image from docker hub
docker pull lifullsetg/gazo-san
Clone this repository
git clone https://github.com/lifull-dev/Gazo-san.git
Go into the repository
cd Gazo-san

Output file:
- output_diff.png: Show the difference on matched parts, it's created base on old image.
- output_delete.png: Show the decrease parts to new image, it's created base on old image.
- output_add.png: Show the increase parts to old image, it's created base on new image.
Each color stands for:
- Green rectangle:
- The parts decrease to new image.
- The parts increase to old image.
- Red rectangle: Matched parts in both image.
- Color in red : Difference in matched part.

Execute image difference calculate.
Usage: ./gazosan PATH_TO_NEW_FILE PATH_TO_OLD_FILE OUTPUT_NAME [options]
options
-v, --verbose Enable verbose output message
--create-change-image Create increase and decrease part image
-h, --help Print help
