103+
attribution notices from the Source form of the Work,
104+
excluding those notices that do not pertain to any part of
105+
the Derivative Works; and
106+
107+
(d) If the Work includes a "NOTICE" text file as part of its
108+
distribution, then any Derivative Works that You distribute must
109+
include a readable copy of the attribution notices contained
110+
within such NOTICE file, excluding those notices that do not
111+
pertain to any part of the Derivative Works, in at least one
112+
of the following places: within a NOTICE text file distributed
113+
as part of the Derivative Works; within the Source form or
114+
documentation, if provided along with the Derivative Works; or,
115+

129+
the conditions stated in this License.
130+
131+
5. Submission of Contributions. Unless You explicitly state otherwise,
132+
any Contribution intentionally submitted for inclusion in the Work
133+
by You to the Licensor shall be under the terms and conditions of
134+
this License, without any additional terms or conditions.
135+
Notwithstanding the above, nothing herein shall supersede or modify
136+
the terms of any separate license agreement you may have executed
137+
with Licensor regarding such Contributions.
138+
139+
6. Trademarks. This License does not grant permission to use the trade
140+
names, trademarks, service marks, or product names of the Licensor,
141+
except as required for reasonable and customary use in describing the

144+
7. Disclaimer of Warranty. Unless required by applicable law or
145+
agreed to in writing, Licensor provides the Work (and each
146+
Contributor provides its Contributions) on an "AS IS" BASIS,
147+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148+
implied, including, without limitation, any warranties or conditions
149+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150+
PARTICULAR PURPOSE. You are solely responsible for determining the
151+
appropriateness of using or redistributing the Work and assume any
152+
risks associated with Your exercise of permissions under this License.
153+
154+
8. Limitation of Liability. In no event and under no legal theory,
155+
whether in tort (including negligence), contract, or otherwise,
156+
unless required by applicable law (such as deliberate and grossly
157+
negligent acts) or agreed to in writing, shall any Contributor be
158+
liable to You for damages, including any direct, indirect, special,
159+
incidental, or consequential damages of any character arising as a
160+
result of this License or out of the use or inability to use the
161+
Work (including but not limited to damages for loss of goodwill,
162+
work stoppage, computer failure or malfunction, or any and all
163+
other commercial damages or losses), even if such Contributor
164+
has been advised of the possibility of such damages.
165+
166+
9. Accepting Warranty or Additional Liability. While redistributing
167+
the Work or Derivative Works thereof, You may choose to offer,
168+
and charge a fee for, acceptance of support, warranty, indemnity,
169+
or other liability obligations and/or rights consistent with this
170+
License. However, in accepting such obligations, You may act only
171+
on Your own behalf and on Your sole responsibility, not on behalf
172+
of any other Contributor, and only if You agree to indemnify,
173+
defend, and hold each Contributor harmless for any liability
174+
incurred by, or claims asserted against, such Contributor by reason
175+
of your accepting any such warranty or additional liability.

# ros2_openvino_toolkit
2+
3+
## 1. Introduction
4+
The [OpenVINO™](https://software.intel.com/en-us/openvino-toolkit) toolkit quickly deploys applications and solutions that emulate human vision. Based on Convolutional Neural Networks (CNN), the Toolkit extends computer vision (CV) workloads across Intel® hardware, maximizing performance.
5+
6+
This project is a ROS2 wrapper for CV API of [OpenVINO™](https://software.intel.com/en-us/openvino-toolkit), providing the following features:
7+
* Support CPU and GPU platforms
8+
* Support standard USB camera and Intel® RealSense™ camera
9+
* Support Video or Image file as detection source
10+
* Face detection
11+
* Emotion recognition
12+
* Age and gender recognition
13+
* Head pose recognition
14+
* Demo application to show above detection and recognitions
15+
16+
## 2. Prerequisite
17+
- An x86_64 computer running Ubuntu 16.04. Below processors are supported:
18+
* 6th-8th Generation Intel® Core™
19+
* Intel® Xeon® v5 family
20+
* Intel® Xeon® v6 family
21+
- ROS2 [Bouncy](https://github.com/ros2/ros2/wiki)
22+
- [OpenVINO™ Toolkit](https://software.intel.com/en-us/openvino-toolkit)
23+
- RGB Camera, e.g. RealSense D400 Series or standard USB camera or Video/Image File
24+
- Graphics are required only if you use a GPU. The official system requirements for GPU are:
25+
* 6th to 8th generation Intel® Core™ processors with Iris® Pro graphics and Intel® HD Graphics
26+
* 6th to 8th generation Intel® Xeon® processors with Iris Pro graphics and Intel HD Graphics (excluding the e5 product family, which does not have graphics)
27+
* Intel® Pentium® processors N4200/5, N3350/5, N3450/5 with Intel HD Graphics
28+
29+
Use one of the following methods to determine the GPU on your hardware:
30+
1. [lspci] command: GPU info may lie in the [VGA compatible controller] line.
31+
2. Ubuntu system: Menu [System Settings] --> [Details] may help you find the graphics information.
32+
3. Openvino: Download the install package, install_GUI.sh inside will check the GPU information before installation.
33+
34+

38+
* [Install from package](https://github.com/IntelRealSense/librealsense/blob/v2.14.1/doc/distribution_linux.md)
39+

```/openvino_toolkit/age_genders```([people_msgs:msg:AgeGenderStamped](https://github.intel.com/otc-rse/ros2_openvino/blob/master/people_msgs/msg/AgeGenderStamped.msg))
140+
- Head Pose:
141+
```/openvino_toolkit/headposes```([people_msgs:msg:HeadPoseStamped](https://github.intel.com/otc-rse/ros2_openvino/blob/master/people_msgs/msg/HeadPoseStamped.msg))
142+
143+
## 7. Known Issues
144+
- Parameters "-m_ag, -m_hp, -m_em" should be optional, but samples throw exception without them.
145+
- Parameters "-n_ag, -n_hp, -n_em" doesn't work. The maximum number of face/age/headpose/emotion is always 16.
146+
- Standard USB camera can be unexpected launched with input parameter "-i RealSenseCamera".
