BCCD Dataset

BCCD Dataset is a small-scale dataset for blood cells detection.
Thanks the original data and annotations from cosmicad and akshaylamba. The original dataset is re-organized into VOC format. BCCD Dataset is under MIT licence.
You can download the .rec format for mxnet directly. The .rec file can be load by mxnet.image.ImageDetIter.

Data preparation

Data preparation is important to use machine learning. In this project, the Faster R-CNN algorithm from keras-frcnn for Object Detection is used.
From this dataset, nicolaschen1 developed two Python scripts to make preparation data (CSV file and images) for recognition of abnormalities in blood cells on medical images.

• export.py: it creates the file “test.csv” with all data needed: filename, class_name, x1,y1,x2,y2.
• plot.py: it plots the boxes for each image and save it in a new directory.

Overview of dataset

• You can see a example of the labeled cell image.
  We have three kind of labels :

  • RBC (Red Blood Cell)
  • WBC (White Blood Cell)
  • Platelets (血小板)

• The structure of the BCCD_dataset

• The JPEGImages:

  • Image Type : jpeg(JPEG)
  • Width x Height : 640 x 480

• The Annotations : The VOC format .xml for Object Detection, automatically generate by the label tools. Below is an example of .xml file.

  <annotation>
  	<folder>JPEGImages</folder>
  	<filename>BloodImage_00000.
  
  
  

数据加载示例（图像类）

from PIL import Image
import glob, os

files = (glob.glob(os.path.join(path, "**", "*.png"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.jpg"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.tif"), recursive=True))
print("图像文件数:", len(files))
img = Image.open(files[0]); print("尺寸/模式:", img.size, img.mode)

# torchvision Dataset 方式:
# from torchvision import datasets
# ds = datasets.ImageFolder(path)  # 要求 子目录=类别
