[`rembg-aws-lambda`](https://pypi.org/project/rembg-aws-lambda/) is a tool to remove images background.

**Check out my similar project, [`profile-photo`](https://github.com/rnag/profile-photo),
which can create a [headshot](https://www.nfi.edu/headshot-photo/) from an image.**
## Requirements
```
python: >3.7, <3.11
```
## Installation
CPU support:
```bash
pip install rembg-aws-lambda
```
GPU support:
First of all, you need to check if your system supports the `onnxruntime-gpu`.
Go to https://onnxruntime.ai and check the installation matrix.
<p style="display: flex;align-items: center;justify-content: center;">
<img src="https://raw.githubusercontent.com/rnag/rembg-aws-lambda/master/onnxruntime-installation-matrix.png" width="400" />
</p>
If yes, just run:
```bash
pip install rembg-aws-lambda[gpu]
```
## Usage as a library
Input and output as bytes
```python
from rembg import remove
input_path = 'input.png'
output_path = 'output.png'
with open(input_path, 'rb') as i:
with open(output_path, 'wb') as o:
input = i.read()
output = remove(input)
o.write(output)
```
Input and output as a PIL image
```python
from rembg import remove
from PIL import Image
input_path = 'input.png'
output_path = 'output.png'
input = Image.open(input_path)
output = remove(input)
output.save(output_path)
```
Input and output as a numpy array
```python
from rembg import remove
import cv2
input_path = 'input.png'
output_path = 'output.png'
input = cv2.imread(input_path)
output = remove(input)
cv2.imwrite(output_path, output)
```
How to iterate over files in a performatic way
```python
from pathlib import Path
from rembg import remove, new_session
session = new_session()
for file in Path('path/to/folder').glob('*.png'):
input_path = str(file)
output_path = str(file.parent / (file.stem + ".out.png"))
with open(input_path, 'rb') as i:
with open(output_path, 'wb') as o:
input = i.read()
output = remove(input, session=session)
o.write(output)
```
## Models
All models are downloaded and saved in the user home folder in the `.u2net` directory.
The available models are:
- u2net ([download](https://github.com/danielgatis/rembg/releases/download/v0.0.0/u2net.onnx), [source](https://github.com/xuebinqin/U-2-Net)): A pre-trained model for general use cases.
- u2netp ([download](https://github.com/danielgatis/rembg/releases/download/v0.0.0/u2netp.onnx), [source](https://github.com/xuebinqin/U-2-Net)): A lightweight version of u2net model.
- u2net_human_seg ([download](https://github.com/danielgatis/rembg/releases/download/v0.0.0/u2net_human_seg.onnx), [source](https://github.com/xuebinqin/U-2-Net)): A pre-trained model for human segmentation.
- u2net_cloth_seg ([download](https://github.com/danielgatis/rembg/releases/download/v0.0.0/u2net_cloth_seg.onnx), [source](https://github.com/levindabhi/cloth-segmentation)): A pre-trained model for Cloths Parsing from human portrait. Here clothes are parsed into 3 category: Upper body, Lower body and Full body.
- silueta ([download](https://github.com/danielgatis/rembg/releases/download/v0.0.0/silueta.onnx), [source](https://github.com/xuebinqin/U-2-Net/issues/295)): Same as u2net but the size is reduced to 43Mb.
