# Sample applications

Source: [https://docs.qualcomm.com/doc/80-70020-50/topic/example-applications.html](https://docs.qualcomm.com/doc/80-70020-50/topic/example-applications.html)

The Qualcomm IM SDK includes sample applications that enable you to explore the AI/ML
        and multimedia features. Additionally, Python-based samples are available for common use
        cases. These applications function as a reference for running custom use cases on Qualcomm
        Linux and Ubuntu Server.

Important: 
                
- Ensure that the host computer uses Ubuntu 22.04.
- [Get started with the Qualcomm IM
                            SDK](https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-51/install-sdk.html) for your Qualcomm Linux 1.5 or Ubuntu Server.
- This document has commands that you must invoke either on the Linux host
                            computer or on the Qualcomm Dragonwing^™^ Development Kits
                            (also referred as target device):

    - **In the terminal of the target device**: Refers to the commands
                                that you must run inside the target device
    - **In the terminal of the host computer**: Refers to the commands
                                that you must run on the Linux host computer
- The sample applications and AI procedures in this guide are compatible with
                        Qualcomm AI^®^ Runtime SDK v2.35 and LiteRT (or TFLite) v2.16.1.
                        Ensure that you download the matching SDKs to your host computer before
                        starting AI/ML development.

Note:
- This guide isn't applicable for Qualcomm Dragonwing^TM^ IQ-615.
- For information about new features, sample applications, resolved issues, and
                    limitations, see [Qualcomm Intelligent Multimedia SDK (IM SDK) Release Notes](https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-52/qim-sdk-release-1-5.html).

Use the following sample applications to run different use cases related to retail, AI
            Edge Box, IP camera, drones, and robotics.

- AI/ML applications focus on the AI and ML capabilities.
- Multimedia applications use the camera, video, and audio features.
- Python-based applications use Python to run the AI/ML and multimedia use cases. For
                more information, see [Python applications](https://docs.qualcomm.com/doc/80-70020-50/topic/python-sample-applications.html).

To run the AI/ML and multimedia sample applications using a GUI-based application without
            any host setup, see [Run sample applications using Qdemo](https://docs.qualcomm.com/bundle/publicresource/topics/80-70020-253/run-sample-apps-qdemo.html#run-sample-applications-using-qdemo).
