image-dataset-converter release

Out image-dataset-converter library keeps evolving and, apart from fixing bugs, we also keep adding useful stuff.

The version of the image-dataset-converter-all library stands now at 0.0.3.

Since version 0.0.2 the following changes occurred:

• image-dataset-converter (core library):

  • switched to the fast-opex library

  • helper method from_indexedpng was using incorrect label index (off by 1)

  • Data.save_image method now ensures that source/target files exist before calling os.path.samefile

  • requiring seppl>=0.2.6 now

  • readers now support default globs, allowing the user to just specify directories as input (and the default glob gets appended)

  • the to-yolo-od writer now has an option for predefined labels (for enforcing label order)

  • the to-yolo-od writer now stores the labels/labels_cvs files in the respective output folders rather than using an absolute file name

  • the bluechannel/grayscale/indexed-png image segmentation readers/writers can use a value other than 0 now for the background

  • split filter has been renamed to split-records

• image-dataset-converter-imgaug: added find-contours filter for turning blobs in image segmentation annotations into object detection polygons.

• image-dataset-converter-imgvis: added add-center-overlay-od overlay filter

• image-dataset-converter-pdf (new module): adds support for PDF, like extracting images from PDF and compiling PDF from images
