title: Velocity Field Estimation on Density-Driven Solute Transport With a Convolutional Neural Network [Dataset]

description: This data set accompanies the manuscript ‘Velocity Field Estimation on Density-Driven Solute Transport With a Convolutional&lt;br&gt;
Neural Network’. Concentration fields are stored as portable pixel maps (.ppm) and flow fields are stored in the&lt;br&gt;
Middlebury .flo file format (&lt;a href="http://vision.middlebury.edu/flow/code/flow-code/README.txt"&gt;http://vision.middlebury.edu/flow/code/flow-code/README.txt&lt;/a&gt;).&lt;br&gt;
description: The data are organized in the following manner:<br>



The synthetic data that is generated by the numerical simulation are contained in the ‘numerical_experiment’ zip-archive.<br>
The archive contains the training and validation data sets in ‘01_training_data_set’ that are used to train and validate the<br>
convolutional neural network. The files ‘img_pair_train_list.txt’ and ‘img_pair_validation_list.txt’ specify the image pairs<br>
and the corresponding true velocity fields of the training and validation data set respectively. The directory<br>
‘velocity_field_estimation_on_validation_set’ contains the estimated velocity fields on the validation data set using the convolutional<br>
neural network.<br>
‘02_test_data_set’ contains the test data set with the image pairs and the corresponding true velocity fields<br>
(also specified in ‘img_pair_test_list.txt’). The directory ‘velocity_field_estimation_on_test_set’ contains the<br>
estimated velocity fields on the test data set using the convolutional neural network.<br>
‘03_propagated_concentration_fields’ contain conentration fields that are propagated by either the true or the estimated<br>
velocity fields.<br>



The data of the laboratory experiment is contained in the ‘laboratory_experiment’ zip-archive. The directory<br>
‘velocity_field_estimation_on_laboratory_experiment’ contains the estimated velocity fields on the laboratory experiment. The<br>
estimated velocity fields with time step index i is estimated between the concentrations fields with time step index i and<br>
index i+1.<br>
