Hi, just wanted to let you know the existence of EcoAssist. It's a no-code interface which makes the use and installation of the MegaDetector model easy. It's free, open-source and available for windows, mac and linux and can (amongst others) filter out the empty images so you don’t have to wade through all of them. 

It can:

• Use either MDv5a or MDv5b to tag animals, persons and vehicles in both images and video's
• Filter out empty images, people, vehicles or animals
• Review and edit annotations using the open-source annotation software labelImg
• Create input file for further processing in Timelapse
• Export .xml label files in Pascal VOC format for further model training
• Manipulate data by drawing boxes or cropping detections
• Use custom models trained from MDv5 using transfer learning
