HPTiny Neural Network

---

Hi!

My name is Claudemir Casa and i created HPTiny, but what is HPTiny?

hptiny is a compact model trained to be faster and smaller. The initial idea of this project is train a model to detect human body visible parts and expand to specific regions. Our model is trained over ONNX, this allows the model to be executed in real time on mobile devices and embedded devices, it also allows the model to be converted to other neural network architectures. The model is not as accurate as a full model, but it's being constantly updated for best results.

I want to answer a few questions:

• Yes, you can use the template for personal and commercial applications with reference to the original author, me :)
• This is a compact model, with less precision.
• To access the database you must contact me via email claudemir.casa@ufpr.br
• You can download published article at HPNET: DETECTING HUMAN PARTS IN THE WILD

What is ONNX?

The Open Neural Network eXchange (ONNX) is an open format to represent deep learning models. With ONNX, developers can move models between state-of-the-art tools and choose the combination that is best for them. ONNX is developed and supported by a community of partners.

Model Visualization

You can see visualizations of each model's network architecture by using Netron or VisualDL.

How to run the model

We provide compressed binary versions of the model here. To execute them simply unzip the specific file and read instructions of readme.txt file.

Dataset

We use a subset of images extracted from Google Open Images Dataset containing 127,000 images that were randomly extracted using the OIDv4_ToolKit tool. The database is really great, if you have interest contact us by email.

Statistics

These are the statistics of the last iteration performed. They are based on a subsample of the original image database that contains 127,000 images.
