0. Introduction

This is the largest lake for many ready-to-use SOTA models.

1. Models: Trained state-of-the-art models for various vision tasks in ONNXRuntime backend
2. No-Code Modules: Easy interface to use those models for both prediction and visualizing output. No coding is needed. The interface is universal among all models in this library.
3. Extentiability: Customizable modules to use it for applications such as realtime inference and web application.

1. Installation

Install directly from this repository.

$cd BiWAKO
$pip install -e .

Warning

Downloading from pip server is currently suspended in order to simplify dependency requirements. We will update it soon.

2. Usage

No matter which model you use, these interface is the same.

import BiWAKO

# 1. Initialize Model
model = BiWAKO.MiDAS(model="mono_depth_small")

# 2. Feed Image (accept cv2 image or path to the image)
prediction = model.predict(image_or_image_path)

# 3. Visiualize result as a cv2 image
result_img = model.render(prediction, image_or_image_path)

More specifically...

1. Instantiate model with BiWAKO.ModelName(weight). The ModelName and weight corresponding to the task you want to work on can be found at the table in the next section. Weight file is automaticaly downloaded.
2. call predict(image). image can be either path to the image or cv2 image array.
3. call render(prediction, image). prediction is the return value of predict() method and image is the same as above. Some model takes optional arguments to control details in the output.

2-2 High Level APIs

We also provides some APIs to even accelerate productions. See API page for further details/

5. Deployment

It is extremely easy to use BiWAKO at application layer.

1. Real Time Prediction

Any model can be used in the same way to run real-time inference.

2. FastAPI Implementation

Like the above example, you can build simple Backend API for inference on web server. We have prepared sample deployment of the library with FastAPI.Read this for details.

3. Video Prediction

We also provides pre-defined video prediction API. Read this for details
