The goal
The overall goal of the competition on Kaggle platform was to build an algorithm that automatically and accurately identifies if a subsurface target is salt or not on seismic images. The task is crucial for oil and gas company drillers. The object of the competition is seismic data collected using reflection seismology. In a nutshell, the problem can be formulated as a semantic segmentation computer vision task.
A salt body depicted on a seismic reflection image (the sample created out of the Challenge data).
Data overview
There were 4000 grayscale images 101x101 px with labeled masks for training. Another set with 18000 images was provided for testing. In addition to the images, the depth of the imaged location was supplied for each image.
A sample image with its binary mask. Green area corresponds to a salt region, whereas blue - no salt.
Evaluation
This competition was evaluated on the mean average precision at different intersection over union (IoU) thresholds. The threshold values range from 0.5 to 0.95 with a step size of 0.05.
