YOLOV2 on Caffe

This is an implementation of YOLO v2 inferenced using Caffe (pyCaffe) framework

What's inside

• Yolo to Caffe model converter (thanks to Duangenquan)

• Sample application of YOLO v2 on PyCaffe (single image) -- caffe-yolov2/yolo_main.py (upgraded version of yolo main from Xingwangsfu)

• Validation, e.g. ..* subprocess script for running the main script several times ..* mAP calculation using VOC dataset (thanks to AlexeyAB)

Supported models

Tiny YOLO v2 cfg weights

How to use it:

NOTE !!! The following instructions assume that you already have a running Caffe distribution in Python.

Caffe v1.0 Installation instruction here

Single image inference

1. Prepare the config file and pre-trained weights of the model (e.g tiny-yolo-voc)
2. Convert it to Caffe representations(.prototxt and .caffemodel) using the provided script
3. Run the yolo_main.py (add -h for arguments instructions)

Validating the performance

1. As an example, we will be using 2012_val.txt from VOC Dataset as our validation sets.
2. Run caffe_valid_run.py to run our YOLO parser in Caffe, yolo_main.py, against the validation sets.
3. It will produce the needed format in folder results
