Description
Generated whistlers with pixel-segmented separate masks for each trace.
File naming:
- train_images.tar.gz contains all the train images (>10 GB)
- example_images.zip contains 5 spectrograms and the corresponding segmentation masks. (~5 MB))
- {id}_rothera_{n}_y.png, {id}_rothera_x.png, where {id} is a unique ID to match the masks and the spectrogram image, {n} enumerates the whistler traces within a spectrogram. Files ending _y.png are the bitmask images, while the _x.png files are the spectrograms.
Opening the bitmasks in a regular image viewer might show only a black image. In this case, opening as a matrix (eg via matplotlib or opencv in python), converting to binary values, and visualizing them can help.
