Or just run this:. Darknet prints out the objects it detected, its confidence, and how long it took to find them. Instead, it saves them in predictions. You can open it to see the detected objects. Since we are using Darknet on the CPU it takes around seconds per image.
If we use the GPU version it would be much faster. The detect command is shorthand for a more general version of the command. It is equivalent to the command:. Instead of supplying an image on the command line, you can leave it blank to try multiple images in a row. Instead you will see a prompt when the config and weights are done loading:.
Once it is done it will prompt you for more paths to try different images. Use Ctrl-C to exit the program once you are done. By default, YOLO only displays objects detected with a confidence of. For example, to display all detection you can set the threshold to We have a very small model as well for constrained environments, yolov3-tiny.
To use this model, first download the weights:. Then run the command:. You can train YOLO from scratch if you want to play with different training regimes, hyper-parameters, or datasets. You can find links to the data here. To get all the data, make a directory to store it all and from that directory run:.
Now we need to generate the label files that Darknet uses. Darknet wants a. After a few minutes, this script will generate all of the requisite files. In your directory you should see:. Darknet needs one text file with all of the images you want to train on. Now we have all the trainval and the trainval set in one big list.
Now go to your Darknet directory. For training we use convolutional weights that are pre-trained on Imagenet. Visit the URL, copy and paste the authorization code, and press enter. Run the make command that builds darknet i. It is important since we cannot use Colab to output images in new windows. We have to use matplotlib. The output shows the model architecture and lastly, it shows the inference time and the predictions along with the confidence.
Other arguments are the same as object detection on images as discussed in the above sections. Here we will be making use of the Google Drive that we mounted on Google Colab. In the below section put the path to the video that you uploaded to your drive.
You can upload the video by visiting your Google Drive. Now we will run the CLI command that we saw in the previous section.
