Silhouette Detection

To collect real-time statistics on human silhouettes, you first have to enable silhouette detection.

In this section:

Enable Silhouette Detection

To enable detection of human silhouettes, do the following:

1. Open the /etc/findface-extraction-api configuration file and add a new detector edie (edie_rc2.cpu.fnk/edie_rc2.gpu.fnk) with relevant settings, as shown in the example below.

   sudo vi /etc/findface-extraction-api.ini
   
   detectors:
     max_batch_size: 1
     instances: 1
     models:
       cheetah:
         model: facedet/cheetah.cpu.fnk
         options:
           min_object_size: 32
           resolutions:
           - 256x256
           - 384x384
           - 512x512
           - 768x768
           - 1024x1024
           - 1536x1536
           - 2048x2048
       edie:
         model: pedet/edie_rc2.cpu.fnk
         options:
           min_object_size: 16
           resolutions:
           - 1280x720
           - 1920x1080
   

   Note

   The values of the edie options in the example are considered optimal. You can adjust them, subject to your cameras’ observation scenes. Contact our experts by support@ntechlab.com if you have any questions.

2. Restart findface-extraction-api.

sudo systemctl restart findface-extraction-api
