The dataset is structured as follows: - Dataset/ - Videos/ - Gauze/ - VID{00{02,03,04,06,07,10,11,13,16,17,18,21,22,23,24,25,28,30}, 01{00,01,02,03,04,05,06,07,08,10,11,12}}.mp4 - NoGauze/ - VID00{05,08,09,12,14,15,19,20,26,27,29,31}.mp4 - Fragments100x100/ - VID00{02,03,04,06,07,10,11,13,16,17,18,21,22,23,24,25,28,30}/ - Gauze/ - VID00XX-$frame_number-$fragment_number.png - NoGauze/ - VID00XX-$frame_number-$fragment_number.png - Masks/ - VID00{02,03,04,06,07,10,11,13,16,17,18,21,22,23,24,25,28,30}/ - Frames/ - VID00XX-$frame_number-frame.png - ... - Masks/ - VID00XX-$frame_number-mask.png - ... The first directory (Videos) contains uncut 720x576 videos as recorded by the laparoscope, these are classified in Gauze and NoGauze directories, based on the presence or absence of gauzes. The naming scheme of this videos corresponds to VID + two digits to indicate different animals + two digits to numerate the videos of that animal. Fragments100x100 directory contains fragments obtained from a portion of the videos sampled every 10 frames. Fragments are classified in Gauze / NoGauze directories, inside a subdirectory indicating their corresponding video. Altought the preprocessed fragments are 100x100 in size, these are generated from the hand-traced masks and can therefore be automatically regenerated in any size. Fragments are named as follows: VIDEO_ID-{0-based index of their frame in the video}-{1-based index of the fragment in a row-major order}. An example of the index fragment in an image with 9 fragments would be: | 1 | 2 | 3 | | 4 | 5 | 6 | | 7 | 8 | 9 | Lastly, the Mask directory includes hand-traced masks from the videos corresponding to the animal 00, sampled every 10 frames. This directory has one subdirectory for every traced video, where two additional subfolders divide Frames and Masks. This table gives an overview of each video where the "Gauzes" column indicates the maximum number of gauzes concurrently in any frame of the video, "Stained" column describes if the Gauze(s) have blood in them, "Objects" column indicates the presence of objects other than gauzes in the video and lastly "Camera" specify if the laparoscope was moving during the recording of the video. | Video | Gauzes | Stained | Objects | Camera | Duration | |:-------:|:------:|:-------:|:----------------------:|:----------:|:--------:| | VID0002 | 1 | Yes | Tools (1) | Movement | 0m49s | | VID0003 | 1 | Yes | Tools (1) | Movement | 1m03s | | VID0004 | 1 | Yes | Tools (1) | Movement | 1m07s | | VID0005 | 0 | - | None | Movement | 1m07s | | VID0006 | 1 | Yes | Tools (1) | Movement | 1m40s | | VID0007 | 1 | Yes | Tools (1), Plastic bag | Movement | 2m45s | | VID0008 | 0 | - | Tools (1) | Movement | 2m43s | | VID0009 | 0 | - | None | Movement | 0m23s | | VID0010 | 1 | Yes | Tools (1) | Movement | 1m42s | | VID0011 | 1 | Yes | Tools (1) | Movement | 1m15s | | VID0012 | 0 | - | Tools (1) | Movement | 0m54s | | VID0013 | 1 | Yes | Tools (1) | Movement | 0m32s | | VID0014 | 0 | - | Tools (2) | Movement | 1m19s | | VID0015 | 0 | - | Tools (2) | Movement | 0m44s | | VID0016 | 1 | Yes | Tools (2) | Static | 1m01s | | VID0017 | 1 | Yes | Tools (1) | Static | 0m50s | | VID0018 | 1 | Yes | Tools (2), Plastic bag | Static | 0m20s | | VID0019 | 0 | - | Tools (1), Plastic bag | Static | 0m52s | | VID0020 | 0 | - | None | Movement | 0m25s | | VID0021 | 1 | Yes | Tools (1) | Movement | 0m41s | | VID0022 | 1 | No | Tools (1) | Movement | 1m28s | | VID0023 | 2 | Both | Tools (1) | Movement | 2m47s | | VID0024 | 2 | Both | Tools (1), Plastic bag | Movement | 1m40s | | VID0025 | 2 | Both | Tools (1), Plastic bag | Movement | 1m01s | | VID0026 | 0 | - | None | Movement | 0m11s | | VID0027 | 0 | - | Tools (1) | Movement | 2m53s | | VID0028 | 2 | Both | Tools (1) | Static | 0m48s | | VID0029 | 0 | - | Tools (1) | Movement | 0m48s | | VID0030 | 2 | Both | Tools (1) | Movement | 5m07s | | VID0031 | 0 | - | None | Movement | 0m33s | | VID0100 | 1 | No | Tools (1) | Static | 0m38s | | VID0101 | 1 | No | Tools (1) | Static | 0m33s | | VID0102 | 1 | No | Tools (1) | Static | 0m43s | | VID0103 | 1 | Yes | Tools (1) | Static | 0m28s | | VID0104 | 1 | Yes | Tools (1) | Movement | 0m39s | | VID0105 | 1 | Yes+ | Tools (1) | Movement | 0m39s | | VID0106 | 1 | Yes+ | Tools (1) | Static | 0m24s | | VID0107 | 1 | Yes+ | Tools (1) | Static | 0m27s | | VID0108 | 1 | Yes | Tools (1) | Static | 0m32s | | VID0110 | 1 | Both | Tools (1) | Static | 0m51s | | VID0111 | 1 | Yes+ | Tools (1) | Static | 0m27s | | VID0112 | 1 | Yes+ | Tools (1) | Static | 0m19s |
