TAPPAS is Hailo's set of full application examples, implementing pipeline elements and pre-trained AI tasks.

Demonstrating Hailo's system integration scenario of specific use cases on predefined systems (software and Hardware platforms). It can be used for evaluations, reference code and demos:

• Accelerating time to market by reducing development time and deployment effort
• Simplifying integration with Hailo’s runtime SW stack
• Providing a starting point for customers to fine-tune their applications

• Hailo-8 device
• HailoRT PCIe driver installed
• At least 6GB's of free disk space

* It is recommended to start your development journey by first installing the Hailo SW Suite

• Cross compile - A guide for cross-compiling

TAPPAS comes with a rich set of pre-configured pipelines optimized for different common hosts.

Pipelines that run a single network. The diagram below shows the pipeline data-flow.

The following table details the currently available examples.

	General	i.MX8	i.MX6	RPi4	x86 Hardware Accelerated	Rockchip

Object Detection
Pose Estimation
Semantic Segmentation

Instance segmentation
Classification with Python Postprocessing
Object Detection Multiple Devices (Century)

Examples of basic pipelines running two networks. The parallel networks pipeline is an simple extension of the single network pipeline and is shown in the following diagram:

The cascaded (serial) flow shows two networks running in series. This example pipeline is of the popular configuration where the first network is a detector which finds some Region-of-Interest (ROI) in the input image and the second network processes the cropped ROI (a face-detection-and-landmarking use case of this pipeline is shown at the top of this guide). The pipeline is shown in the following diagram:

	General	i.MX8	i.MX6	RPi4	x86 Hardware Accelerated	Rockchip
Parallel - Object Det + Depth Estimation
Parallel - Object Det + Pose Estimation
Cascaded - Face Detection & Landmarks
Cascaded - Person Det & Single Person Pose Estimation
Cascaded - Face Detection & Recognition

Our LPR reference application demonstrates the use of 3 networks, with a database. The pipeline demonstrates inference based decision making (Vehicle detection) for secondary inference tasks (License plate data extraction). This allows multiple networks to cooperate in the pipeline for reactive behavior.

Our Multi-Person Multi-Camera Tracking reference application demonstrates person tracking across multiple streams using RE-ID tracking. The pipeline demonstrates another method for inference based decision making that also connects between different video streams.

Our VMS reference application demonstrates the use of 5 networks over multiple streams, and is a reference for video management system applications.
