Applications Example - Switch Detection Video
This application offers a graphical interface for users to run an object detection demo using either CPU or GPU/NPU to perform inference on a video file.
- Run the Switch Detection Video demo using the following line:
$ pyeiq --run switch_video
- Type on CPU or GPU/NPU in the terminal to switch between cores.
- This runs inference on a default video:
Demos Example - Running Object Detection SSD
Object detection is a computer technology related to computer vision and image processing that deals with detecting instances of semantic objects of a certain class (such as humans, buildings, or cars) in digital images and videos. Well-researched domains of object detection include face detection and pedestrian detection. Object detection has applications in many areas of computer vision, including image retrieval and video surveillance.
- Run the Object Detection Default Image demo using the following line:
$ pyeiq --run object_detection_tflite
* This runs inference on a default image:
- Run the Object Detection Custom Image demo using the following line:
$ pyeiq --run object_detection_tflite --image=/path_to_the_image
- Run the Object Detection Video File using the following line:
$ pyeiq --run object_detection_tflite --video_src=/path_to_the_video
- Run the Object Detection Video Camera or Webcam using the following line:
$ pyeiq --run object_detection_tflite --video_src=/dev/video<index>
