# ByakuganVisualizer

The ByakuganVisualizer repository hosts a Python tool designed to compare images and highlight their differences.
It simplifies the process of identifying disparities between images, making it ideal for tasks like testing and quality
assurance.
Moreover, it offers a color filter that can be used to correct images for **color-blind users**.

## Installation

```bash
pip install byakuganvisualizer
```

## Usage

### Command Line Interface

```
usage: byakugan_vision [-h] [--version] [--diff DIFF] [--filter {red,blue,green,yellow}] [--images IMAGES] [--deuteranomaly DEUTERANOMALY]
[--protanomaly PROTANOMALY] [--out_dir OUT_DIR]

ByakuganVisualizer: Tool for correcting the color palett for color blind people and highlighting differences of images.

options:
-h, --help show this help message and exit
--version show program's version number and exit
--diff DIFF String containing a list of tuples "Path_To_Image1a,Path_To_Image2a;Path_To_Image1b,Path_To_Image2b...". Each tuple
contains two paths to images to be compared.
--filter {red,blue,green,yellow}
Filter type (red, blue, green, yellow)
--images IMAGES List of image names to be manipulated by a filter. E.g.: A,B,C,D
--deuteranomaly DEUTERANOMALY
Expresses your degree of deuteranomaly, which will be used to correct the image. Default is 1.
--protanomaly PROTANOMALY
Expresses your degree of protanomaly, which will be used to correct the image. Default is 1.
--out_dir OUT_DIR Output directory for the difference images
```

### Python API

Please read the API documentation for the classes `Byakugan` and `ImageFilter` for more information.
You can simply import the classes as follows:

```python
from byakuganvisualizer.Byakugan import Byakugan
from byakuganvisualizer.ImageFilter import ImageFilter
```

## Image Correction for Color Blind People

In the following examples the image is corrected for deuteranomaly and protanomaly.
Correction in this context means that the image is adjusted to be more distinguishable for color-blind people.

**Note:** The float values for deuteranomaly and protanomaly are between 0 and 10. The default value is 1.
The used algorithm is based on the following paper: https://arxiv.org/abs/1711.10662.

The image used in the example is from the following source:
https://www.anime2you.de/news/606180/naruto-feiert-20-anime-jubilaeum/

### Deuteranomaly Correction

```bash
byakugan_vision --images "tests/test_images/naruto.jpg" --deuteranomaly 2
```

### Protanomaly Correction

```bash
byakugan_vision --images "tests/test_images/naruto.jpg" --protanomaly 2
```

### Deuteranomaly and Protanomaly Correction

```bash
byakugan_vision --images "tests/test_images/naruto.jpg" --deuteranomaly 2 --protanomaly 2
```

```bash
byakugan_vision --images "tests/test_images/naruto.jpg" --deuteranomaly 0.5 --protanomaly 0.5
```

### Filter an Image

```bash
byakugan_vision --images "tests/test_images/naruto.jpg" --filter red
```

## Differences between images

The left image used in the example is from the following source:
https://www.anime2you.de/news/606180/naruto-feiert-20-anime-jubilaeum/

### Difference with no Filter

```bash
byakugan_vision --diff "tests/test_images/naruto.jpg,tests/test_images/naruto_modified.jpg" --out_dir tests/test_images/diff
```

Note: The output depends on the order of the images in the tuple. The first image is subtracted from the second image.
That is why the following command results in a different output:

```bash
byakugan_vision --diff "tests/test_images/naruto_modified.jpg,tests/test_images/naruto.jpg" --out_dir tests/test_images/diff
```

### Red Filtered Difference

```bash
byakugan_vision --diff "tests/test_images/naruto.jpg,tests/test_images/naruto_modified.jpg" --filter red --out_dir tests/test_images/diff
```

### Blue Filtered Difference

```bash
byakugan_vision --diff "tests/test_images/naruto.jpg,tests/test_images/naruto_modified.jpg" --filter blue --out_dir tests/test_images/diff
```

### Green Filtered Difference

```bash
byakugan_vision --diff "tests/test_images/naruto.jpg,tests/test_images/naruto_modified.jpg" --filter green --out_dir tests/test_images/diff
```

### Yellow Filtered Difference

```bash
byakugan_vision --diff "tests/test_images/naruto.jpg,tests/test_images/naruto_modified.jpg" --filter yellow --out_dir tests/test_images/diff
```

## Byakugan

The [Bykugan](https://naruto.fandom.com/wiki/Byakugan) from Naruto is a powerful ability that grants users the ability
to see through objects, detect chakra, and perceive long distances, but users are born blind, relying solely on this
special vision.
