Yolo

Python wrapper

 * https://github.com/thomaspark-pkj/pyyolo outputs bounding box to text file. use opencv2.4 due to waitkey issue and not 3.3.0

 * https://timebutt.github.io/static/how-to-train-yolov2-to-detect-custom-objects/ sites https://pjreddie.com/darknet/yolo/ training data set.  from Nils Tijtgat. YOLOv2 is known to struggle when detecting small objects. The Darknet Google Groups has many different topics on how you could improve performance, you could have a look there to find inspiration. A suggestion that is often repeated is to train YOLOv2 using a higher input resolution, instead of 416x416. See this or this for instance. |sort:relevance/darknet/MumMJ2D8H9Y/n6nAIM0EAgAJ yolo small google groups1, yolo small 2 google groups

 * how to use yolo weights

darknetfanz
train yolo coco data The first time I made a custom dataset that ran the 'demo' argument I changed yolo.c line 13 "char *voc_names[]=..." to reflect my custom classes. The second time I made a custom dataset, I added an argument to darknet.c "-override_vocnames" that loaded the appropriate "names=" file from the data file. ie - coco.data
 * Maybe not the best way to do it. But it was easy to implement.

thtrieu
https://github.com/thtrieu/darkflow json output can be generated with descriptions of the pixel location of each bounding box and the pixel location. Each prediction is stored in the sample_img/out folder by default. An example json array is shown below.

Sai

 * https://github.com/saiprabhakar/darknet-modified/tree/v0 Outputs image labels and bounding box to text file. When a person walking down the street veers unto the driveway, his position changes triggering an alert. https://groups.google.com/forum/#!topic/darknet/ylEWe3JUKrE

Guanghan

 * https://github.com/Guanghan/darknet This fork repository adds some additional niche in addition to the current darkenet from pjreddie. e.g. (1). Read a video file, process it, and output a video with boundingboxes.

I am wondering the answer of original question. Can we get coordinates and count of detected objects, as text output, in darknet?

yes you can, go to in folder src/image.c find draw_detection function, left,right,top,bot is image bounding box, names[class] is object name, you can save bounding box and object in txt and count the object

http://guanghan.info/projects/ROLO/ Rolo a fork of Yolo does realtime tracking and identification of the body parts of a human such as face, allowing the Tracked vehicle robot's PepperBall gun accurate engagement. https://github.com/Guanghan/ROLO.

face tracking
https://www.youtube.com/watch?v=UsOi1BfunnU https://github.com/xhuvom/darknetFaceID  i] To detect face from live camera feed and annotate automatically, use the .cfg and .weight files from QuanHua (https://mega.nz/#F!GRV1XKbJ!v8BCsFO8iJVNppiGXY4qMw). [ii] Only add those lines on src/image.c file of this fork as described bellow:

(line #223) to save .jpg images and (line #227) to save annotations on separate folders for each class (also change class number on line #229

[iii] After modifications, run the detector from live webcam or video file which specifically shows only one particular persons face. [iv] Repeat the process for every persons you want to recognize and modify training data location and class number accordingly. About ~2k face images per person is enough to recognize individual faces but to improve accuracy, more data could be added.

 * https://www.youtube.com/watch?v=DeCFxPQlOVk indian traffic data, https://github.com/ctmackay/darknet  , Track 1 utilized the Darknet framework with Yolo object detection. We achived 2nd place in mean average precision for the AI city challenge using this network and training parameters. You will need to build darknet in order to train and run inference on the models. i need to contact nvidia representative, they own the rights to the dataset, I may not have permission to release the models. I am meeting with them on the 6th, i will get back to you.

Uses a TitanX GPU($600) with Yolo to identify objects, draw bounding box and pass the coordinates to say thirty separate Tracked vehicle bots with cost effective CPU running OpenTLD. Ideal solution is to implement yolo on FpGa.
