Data

Warwick-NTU Multi-camera Forecasting (WNMF) dataset

O. Styles, T. Guha, V. Sanchez, and Alex Kot, "Multi-Camera Trajectory Forecasting: Pedestrian Trajectory Prediction in a Network of Cameras," in IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) Workshops, pp. 1016-1017, Seattle, USA, June 2020

The WNMF dataset contains footage of individuals traversing the Nanyang Technological University (NTU) campus. The dataset contains cross-camera tracking information, such that future trajectories of individuals can be anticipated across multiple camera views. The data was collected over a span of 20 days using 15 different CCTV cameras. This was not a controlled collection (i.e., it was collected in real-world conditions).

Sample videos and topology of the camera networks used to create the WNMF dataset

Raw data statistics:

We release camera entrance and departure videos, pre-computed tracking information and RE-ID features. Faces are blurred using the RetinaFace algorithm [1] to detect faces. Provided are the 4 seconds proceeding a camera departure event and 12 seconds following a camera entrance event, totally 16 seconds for each verified cross-camera match.

CityWalks dataset

O. Styles, T. Guha, and V. Sanchez, "Multiple Object Forecasting: Predicting Future Object Locations in Diverse Environments," in Winter Conference on Applications of Computer Vision, pp. 690-699, Colorado, USA, March 2020

We introduce the problem of multiple object forecasting (MOF). MOF follows the same formulation as the popular multiple object tracking (MOT) task, but rather is concerned with predicting future object bounding boxes and tracks in upcoming video frames, rather than the bounding boxes and tracks in the current frame.

Multiple object forecasting

We have constructed the CityWalks dataset to train and evaluate models for MOF. CityWalks contains a total of 501 20-second video clips of which 358 contain at least one valid pedestrian trajectory. We extract footage from the online video-sharing site YouTube. Each original video consists of first-person footage recorded using an Osmo Pocket camera with gimbal stabilizer held by a pedestrian walking in one of the many environments for between 50 and 100 minutes. Videos are recorded in a varΒ­Β­Β­iety of weather conditions, as well as both indoor and outdoor scenes. Dataset statistics are shown in Table 3. The dataset is available here πŸ“¦

IMAC: Image-music emotion dataset

G. Verma, E. G. Dhekane and T. Guha, "Learning Affective Correspondence between Music and Image," in IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), pp. 3975-3979, Brighton, UK, May 2019

To facilitate the study of cross-modal emotion analysis, we constructed a large scale database, which we call the Image-Music Affective Correspondence (IMAC) database. It consists of more than 85,000 images and 3,812 songs (approximately 270 hours of audio). Each data sample is labelled with one of the three emotions: positive, neutral and negative. The IMAC database is constructed by combining an existing image emotion database (You et al., 2016) with a new music emotion database curated by us (Verma et al., 2019). The dataset is available here πŸ“¦

TED1.8k: TED talks popularity prediction dataset with YouTube metadata

R. Sharma, T. Guha and G. Sharma, "Multichannel Attention Network for Analyzing Visual Behavior in Public Speaking," in 2018 IEEE Winter Conference on Applications of Computer Vision (WACV), pp. 476-484, Lake Tahoe, NV, 2018

To facilitate the study of public speaking behaviour, we construct a large video database, namely the TED1.8K database. This database contains 1864 TED talk videos and their associated metadata collected from YouTube. The YouTube metadata collected for each video are the number of likes, dislikes, views and comments. Table 1 presents a summary of the database.

Sample frames from the TED1.8K database, which demonstrates the huge variability, and the challenging nature of the database

 

The TED1.8K dataset provides certain advantages for studying human behaviour in public speaking. Firstly, the video content is carefully created to have well defined audiovisual structure, with subtitles and transcripts of the talks. Therefore, the database offers opportunities for rich multimodal studies. Secondly, the TED talks are of diverse topics, and popular worldwide. Hence, the YouTube ratings are expected to come from viewers with varied demographics, age group, and social background, making the ratings rich and reliable. The dataset is available here πŸ“¦

Live Videos (LV) dataset

R. Leyva, V. Sanchez, and C.-T. Li, "The LV Dataset: a Realistic Surveillance Video Dataset for Abnormal Event Detection," in 5th International Workshop on Biometrics and Forensics (IWBF2017), pp. 1-6, Coventry, UK, April 2017

The LV dataset comprises video sequences characterized by the following aspects:

1. Realistic events without actors performing predefined scripts with a diverse subject interaction.
2. Highly unpredictable abnormal events in different scenes, some of them of very short duration.
3. Scenario correspondence, where the training and test data are captured from the same scene.
4. Challenging environmental conditions.

The LV dataset consists of 30 sequences with 14 different abnormal events. The main characteristics of this dataset are given in Table 4.

All sequences in the LV dataset contain both abnormal and normal behaviour. The labelled frames are provided along with the dataset. The regions of interest (ROIs) are provided in a separate sequence of the same length as that of the training/testing sequence. A separate file is provided with the timestamps to determine the frames to be used for training and those for each sequence. The dataset is available here πŸ“¦
