The Leap Signature Dataset (LSD) consists of signatures from 60 unique subjects in the form of 3D signature trajectories. The trajectories are captured in 3D space without any tactile feedback using a Leap Motion device. The data for each subject consists of 12 samples of genuine signatures and 3 samples of impostor signatures. The data for each subject is captured in a single session. The Leap Signatue Dataset was captured along with the face identities of the subjects. However, to protect the identities of the subjects, we have provided the Leap Signature samples only.

The Head-image Soft Biometric Database (HSBD) consists of head images captured using 2 different DSLR cameras. It has head-images for 103 subjects. This database contains no facial informations and include some angular movements. The database also includes the ground truth annotations of the head in the acquired head-image.

Bag-of-Lies is a multi-modal dataset consisting of video, audio and eye gaze from 35 unique subjects collected using a carefully designed experiment for the task of automated deception detection (binary classification into truth/lie). It has a total of 325 manually annotated recordings consisting of 162 lies and 163 truths. Along with it, EEG (13 channels) data is also available for 22 unique subjects.

For the experiment, each subject was shown 6-10 select images and were asked to describe them deceptively or otherwise based on their choice. Video and Audio were captured using a standard phone camera and microphone, gaze data was collected using GazePoint GP3 Eye tracking system and EEG Data was captured using EPOC+ headset.

In the CAAXR dataset, a total of 1,749 chest X-Rays from the publicly available BIMCV database have been annotated by six radiologists from Mahajan Labs (Mahajan Imaging, New Delhi, India). All the six radiologists had more than 5 years experience, with two among them having 10 and 15 years of experience of reading chest X-rays. All the X-rays were annotated only once by a single radiologist. X-rays with doubtful findings were discussed, and consensus resolution was obtained by the independent effort of the annotator.

Four evaluation protocols for CAAXR database are introduced. Three out of four protocols are designed for classification, and one for segmentation. All protocols use 5-fold cross-validation. The baseline results for semantic segmentation use three segmentation models- UNet, SegNet, and Mask-RCNN. The classification performance is evaluated using four deep learning models namely - DenseNet121, MobileNetv2, ResNet18, and VGG19. The models are evaluated using only train and validation splits, ensuring a fair estimate of the models’ performance on the testing data.

The protocol CSVs can be downloaded from here.

The annotations for the chest X-rays are provided here.
