title: NTU Dataset

description: **************** NTU Dataset ReadMe file *******************<br>Attached files contain our data collected inside Nanyang Technological University Campus for pedestrian intention prediction. The dataset is particularly designed to capture spontaneous vehicle influences on pedestrian crossing/not-crossing intention. <br>We utilize this dataset in our paper "Context Model for Pedestrian Intention Prediction using Factored Latent-Dynamic Conditional Random Fields" submitted to IEEE Transactions on Pattern Analysis and Machine Intelligence.<br>The dataset consists of 35 crossing and 35 stopping* (not-crossing) scenarios. The image sequences are in 'Image_sequences' folder. <br>'stopping_instants.csv' and 'crossing_instants.csv' files provides the stopping and crossing instants respectively, utilized for labeling the data and providing ground-truth for evaluation. Camera1 and Camera2 images are synchronized. Two cameras were used to capture the whole scene of interest.<br>We provide pedestrian and vehicle bounding boxes obtained from [1]. The occlusions and mis-detections are linearly interpolated. All necessary detections are stored in 'Object_detector_pedestrians_vehicles' folder. Each column within the csv files ('car_bndbox_..') corresponds to a unique tracked car within each image sequence. Each of the pedestrian csv files ('ped_bndbox_..') contains only one column, as we consider each pedestrian in the scene separately. <br>Additional details:* [xmin xmax ymin ymax] = [left right top down] (for the bounding boxes)* Dataset frequency: 15 fps.* Camera parameters (in pixels): f = 1135, principal point = (960, 540).<br><br>Additionally, we provide semantic segmentation output [2] and our depth parameters. As the data were collected in two phases, there are two files in each folder, highlighting the sequences in each phase.<br>Crossing sequences 1-28 and stopping sequences 1-24 were collected in Phase 1, while crossing sequences 29-35 and stopping sequences 25-35 were collected in Phase 2.<br>We obtained the optical flow from [3]. Our model (FLDCRF and LSTM) codes are available in 'Models' folder.<br><br>If you use our dataset in your research, please cite our paper:<br>"S. Neogi, M. Hoy, W. Chaoqun, J.
