The implementation of YOLO v2 with TensorFlow

YOLO_v2

This is implementation of YOLO v2 with TensorFlow.

Demo

Installation

1. Clone YOLO_v2 repository

   $ git clone https://github.com/leeyoshinari/YOLO_v2.git
   $ cd YOLO_v2

2. Download Pascal VOC2007 dataset, and put the dataset into data/Pascal_voc.

   If you download other dataset, you also need to modify file paths.

3. Download weights file yolo_weights for COCO, and put weight file into data/output.

   Or you can also download my training weights file YOLO_v2 for VOC.

4. Modify configuration into yolo/config.py.

5. Training

   $ python train_val.py

6. Test

   $ python test_val.py

7. For more information to wiki.

Darknet-19

Darknet-19 has 19 convolutional layers, it's faster than yolo_v2. If you use darknet-19, you need some modifications. It's easy to modify.

Please download Darknet-19 weights file for VOC from darknet-19.

Training on Your Own Dataset

To train the model on your own dataset, you should need to modify:

1. Put all the images into the Images folder, put all the labels into the Labels folder. Select a part of the image for training, write this part of the image filenames into train.txt, the remaining part of the image filenames written in test.txt. Then put the Images, Labels, train.txt and test.txt into data/dataset. Put weight file in data/output.

2. config.py: modify the CLASSES.

3. train.py: replacefrom pascal_voc import Pascal_voc with from preprocess import Data_preprocess, and replace pre_data = Pascal_voc() with pre_data = Data_preprocess().

Requirements

1. Tensorflow
2. OpenCV
