Retrieval of saved objects #1

Closed hackermd closed 8 years ago

hackermd commented 8 years ago

The current approach for saving and retrieving objects is based on outline coordinates of objects.

  1. Outlines of objects in the labeled image are determined for each object: skimage.measure.find_contours()
  2. y, x coordinates are saved in the HDF5 file
  3. Coordinates are retrieved from the file
  4. The label image is reconstructed: cv2.fillPoly()

It needs to be tested whether this approach works reliably for different types of objects...

The whole approach has changed in the meanwhile. Outlines are stored as polygons in the database and the label images are reconstructed from the polygon coordinates.
