Processing Block Sample
At this page, you'll learn how to run the Processing Block Demo Sample on Windows and Linux.
The processing_block_demo sample demonstrates the usage of Processing Block API and compatible components.
To run the processing_block_demo sample you need to install Face SDK 3.15 or higher with Windows or Linux platform files (according to your operating system).
If Face SDK is not installed, follow the installation instructions Getting Started. Select platform in the "Selection Components" section.
If Face SDK is installed without Windows or Linux platform files, use the utility maintenancetool and install platform by selecting it in the "Selection Components" section.
How to launch
Startup arguments:
--input_image
- required, path to the input image file--unit_type
- optional, type of used processing block, default value is "objects", see the list of available types below--sdk_path
- optional, path to the Face SDK directory, default value is ".." to launch from the default location {Face SDK}/bin--use_cuda
- optional, acceleration of compatible blocks on GPU (CUDA), see Requirements
The basic format of console command to launch processing_block_demo from the bin directory:
- Linux:
./processing_block_demo [--input_image <path_to_image>] [--unit_type <type_of_processing_block>] [--sdk_path <path_to_sdk_directory>] [--use_cuda]
- Windows:
.\processing_block_demo.exe [--input_image <path_to_image>] [--unit_type <type_of_processing_block>] [--sdk_path <path_to_sdk_directory>] [--use_cuda]
List of available processing blocks (unit types)
- face - Face Detector
- body - Human Body Detector
- objects - Object Detector
- pose - Human Pose Estimator
- emotions - Emotion Estimator
- age - Age Estimator
- gender - Gender Estimator
- liveness - 2D RGB Liveness Estimator
- quality - Quality Assessment Estimator
Launch example
Console commands to launch the sample from the bin directory with the "body" processing block (unit type):
- Linux:
./processing_block_demo --input_image group/01.jpg --unit_type body
- Windows:
.\processing_block_demo.exe --input_image group\01.jpg --unit_type body
The results of processing will be displayed in the window.
Result of body detection
Error messages, if any, are also printed in the console.
Troubleshooting
Error
Assertion failed (ERROR: not found libonnxruntime.so), error code: 0x032ad038
:- Check existence of the file lib/libonnxruntime.so in the Face SDK's root directory
- Add the path to the directory that contains the file libonnxruntime.so to environment variable
LD_LIBRARY_PATH
Error
Assertion failed (ERROR: not found onnxruntime.dll), error code: 0x032ad038
:- Check existence of the file bin\onnxruntime.dll in the Face SDK's root directory
Source code of the processing_block_demo sample available at the link. Also, the source code and instructions of building (file README.txt) are available in the examples/cpp/ directory of the Face SDK distributive.
