The goal of the ISL Image Databases is to share image data sets with researchers around the world. The ISL image databases consist of five major parts: medical image databases, fatigue image databases, face and eye databases, facial expression databases, and human activity databases.

RPI ISL Image Databases

1. Face and Eye Databases

1.1. ISL WebImage Database    license

This database is collected from website by our own research group. It can be used in many applications such as face detection, eye detection, and face pose estimation.

1.2. ISL Face Database    license

This database is created by our own research group. It consists of video sequences and static images. It can be used in many applications such as face and eye detection, face tracking, face pose estimation, and face recognition.

1.3. ISL Eye Image Database (Partially available)

This database is constructed by our own research group. It consists of image sequences taken under IR cameras. Each image sequence is decomposed into dark pupil image sequence and its corresponding bright pupil image sequence. This database is primarily used in eye detection and tracking.

1.4. Training Image Databases (Partially available)

The training image databases contain the cropped image region of interest (ROI) for training various classifiers including eye, eye corner, and face.

2. Facial Expression databases

2.1. ISL Facial Expression Databases    license

This database is collected by our own research group. It is primarily used for facial action unit recognition. It consists of two subsets: frontal-view facial expression database and multi-view facial expression database.

2.2. ISL Enhanced Cohn-Kanade AU-coded Facial Expression Database    license

Our research group has manually created more groundtruth data for Cohn-Kanade AU-coded facial expression database including the frame-by-frame AU labeling and coordinates of 34 facial feature points.

3. Human Fatigue Database

4. Medical Image Databases (Partially available)

5. Activity Databases

Databases from Other Research Groups

1. Face Databases

1.1. General Face Databases (for multipie purposes)

1.2. Facial Landmark Databases

1.3. Head Pose Databases

1.4. Facial Expression Databases

1.5. Face Recognition Databases

1.6. Other Face Databases

2. Eye Databases

3. Attribute Databases

4. Other Computer Vision Databases
