Dataset

The dataset consists of a collection of 17 multi-layer cervical cell volumes, from which 8 will be used for training and 9 for testing. Details of the dataset will be released later.

Dataset Release Schedule

December 1st, 2014: Release of 8 annotated multi layered cytology volumes, where four are part of the training set and four are from the testing set. The annotation contains the delineation of each cervical cell (cytoplasm and nucleus). We will also release the evaluation code written in Matlab.
January 1st, 2015: Release of the remaining 9 multi layered cytology volumes. We will provide manual annotation only for the training volumes.

Release 1, 1st Dec 2014
- 4 multi-layer cervical cell volumes for training.
- 4 multi-layer cervical cell volumes for testing.
- Evaluation Code.
  
  *The first release of dataset provide annotations of cytoplasm for each cell and nucleus in the training set. For the testing set, we only provide the 20 focals for each cytology image and the EDF images, without annotation.

Release 2, Jan 2015
- Rest 4 multi-layer cervical cell volumes for training.
- Rest multi-layer cervical cell volumes for testing.
  
  * The usage of this data release is the same as that in the first release.

Annotation for Testset
- Annotation for Test set

How to Use Evaluation Function?

The evaluateion code is used to quantitatively assess the segmentation performance. It consists of two functions:

evaluateCytoSegmentation.m: Function to evaluate the result.
SegEvaluateJIDiceTPRFPR.m: Function about the evaluation measurement, called by evaluateCytoSegmentation.m.

You need to load the cytoplasm annotation of each cell into a Matlab Cell structure before you call the function evaluateCytoSegmentation.m to start evaluating. For example, cell GroundTruth{numImage_i,1}{CellID_j,1} refers to the j-th cell annotation of image i. Therefore,we suggest your results of segmentation are organized in the same way.
