Dataset


NBI-InfFrames dataset 

The NBI-InfFrames dataset aims to provide the surgical data science community with a labeled dataset for the identification of informative endoscopic video frames.

It is composed of 720 video frames. The frames are manually extracted and labeled from 18 narrow-band imaging (NBI) laryngoscopic videos of 18 different patients affected by laryngeal spinocellular carcinoma (diagnosed after histopathological examination).

The frames include 180 informative (I) video frames, 180 blurred (B) frames, 180 frames with saliva or specular reflections (S) and 180 underexposed (U) frames.

Nephrec9 Dataset

“Nephrec9” dataset contains frames of 14 steps of Robot-Assisted Partial Nephrectomy (RAPN) surgery. “Nephrec9”dataset is divided into testing, training and validation sets from 9 full video annotations of RAPN, annotated by an expert renal surgeon. The videos were divided into small videos of 30 seconds or 720 frames, processed at 24 FPS to capture the relevant step context for making predictions and to divide them manually into different datasets. We extracted a total of 1262 videos, out of which we used 769 (approx. 60%) for training, 372 (approx. 30%) for validation and 121 (approx. 10%) as a test dataset.

RAPN consists 14 steps:

  1. mobilization
  2. dissection
  3. identification
  4. ultrasound
  5. marking
  6. clamping
  7. resection
  8. midollar suturing
  9. cortical suturing
  10. unclamping
  11. inspection
  12. removal
  13. reconstruction
  14. drainage

The Laryngeal Dataset

The Laryngeal Dataset  aims to provide the computer assisted surgery community with a dataset for the validation of cancerous tissue classification algorithms.

It is composed of 1320 patches of healthy and early-stage cancerous laryngeal tissues extracted from 33 narrow-band laryngoscopic images of 33 different patients affected by laryngeal spinocellular carcinoma (diagnosed after histopathological examination).

Four patches, relative to the four analyzed laryngeal tissue classes, are extracted from the laryngoscopic image. Blue: tissue with intraepithelial papillary capillary loop-like vessels (IPCL); Red: tissue with Leukoplakia (Le); Green: healthy tissue (He); Yellow: tissue with hypertrophic vessels (Hbv). Figure modified from Moccia et al., 2017.

The EndoAbS Dataset

The EndoAbS Dataset (Endoscopic Abdominal Stereo Images Dataset) aims to provide the computer assisted surgery community with a dataset for the validation of 3D reconstruction algorithms.

It is composed of:

  • 120 pairs of endoscopic stereo images of abdominal organs (liver, kidney, spleen);
  • corresponding ground truth in left­camera reference frame, generated using a laser scanner;
  • camera calibration parameters;

The images were captured under different conditions:

  • 3 different light levels;
  • presence of smoke;
  • two phantom­endoscope distances (~5cm or ~10cm);

The TrackVes dataset

The TrackVes dataset provides to the computer assisted surgery community a dataset for the validation of soft tissue tracking algorithms.

It is composed of:

– 3 video sequences of ex-vivo organs (kidney and liver);
– 6 video sequences of in-vivo organs (real abdominal surgical scenes);

The C++ code implementing the ground truth generation and the tracking algorithm evaluation is available on Bitbucket –
