+<h2>Arabidopsis seeds count using Tensorflow Faster-RCNN model</h2>
+<h3>1 Tensorflow object detection API installation</h3>
+  tensorflow version lower than 2.0.
+  please see: 
+  https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md
+
+<h3>2 Seed annotation</h3>
+  we use LabelImg annotate our seeds, LabelImg generate a xml annotation file.<br>
+  LabelImg please see: https://github.com/tzutalin/labelImg<br>
+  For our project, we split one whole plate image into 4 quater images and annotate quater images mannually.<br>
+  <b>a. split image:</b><br>
+<i>python 00_split_scan_images.py</i><br>
+<b>b. seed annotation</b>
+  <img src="https://github.com/FanruiMeng/Arabidopsis_seed_count/blob/master/Images/seeds_annotation.png?raw=true"  alt="Seed annotation" height="200" width="300"/>
+<h3>3 Xml file transform to csv file</h3>
+  <i>pyhton 02_xml_to_csv.py</i><br>
+  
+  Results is a csv file, like this:<br><br>
+  <table>
+  <tr><td><b>filename</b></td> <td><b>width</b></td> <td><b>height</b></td> <td><b>class</b></td> <td><b>xmin</b></td><td><b>ymin</b></td><td><b>xmax</b></td><td><b>ymax</b></td></tr>
+  <tr><td>scan21_111918022.jpg</td> <td>2900</td> <td>2900</td> <td>seed</td> <td>1325</td><td>813</td><td>1352</td><td>837</td></tr>
+  <tr><td>scan21_111918022.jpg</td> <td>2900</td> <td>2900</td> <td>seed</td> <td>664</td><td>1094</td><td>691</td><td>1116</td></tr>
+  <tr><td>..</td> <td>..</td> <td>..</td> <td>..</td> <td>..</td><td>..</td><td>..</td><td>..</td></tr>

+<h3>4. seed_labels.csv transform to tensorflow tfrecord file </h3>
+
+  <i>python 02_generate_tfrecord.py --csv_input=annotation/seeds_labels.csv --output_path=train.record</i>
+
+<h3>5 Download tensorflow object detection api pre-trained faster rcnn model to work directory.</h3>
+  wget http://download.tensorflow.org/models/object_detection/faster_rcnn_inception_v2_coco_2018_01_28.tar.gz<br>
+  unzip faster_rcnn_inception_v2_coco_2018_01_28.tar.gz
