Ground truth dataset of birds

This dataset was used in the following scientific publication of the method Connected Oriented Image Foresting Transform (COIFT), which extends the previous Oriented Image Foresting Transform (OIFT):

    Oriented Image Foresting Transform Segmentation: Connectivity Constraints with Adjustable Width. XXIX Conference on Graphics, Patterns and Images (SIBGRAPI). Oct 2016, São José Dos Campos, SP, Brazil, pp. 289-296.

To evaluate our method we designed a new ground truth database of 50 public images of birds[1], which is available here. This dataset contains objects with thin and elongated parts.
