CREATED DATASETS

DeitY-TU Face Database


            The human face is considered as the most salient feature for biometric identification compared to other biometric features such as finger geometry, iris, retina, signature, keystroke, etc., as it can also be acquired without the person’s knowledge. It continues to be the most popular and fast growing research area of computer vision and machine learning.In recent years, the development of different face image databases has greatly increased. Some of these databases have been designed for the specific needs of the algorithm under development. Here, various databases have been reviewed based on key features such as number of subjects, total number of images available in the database, conditions under which the images were taken, resolution, image type, i.e., whether the image is visual or thermal; whether the image is color or gray level image, etc.

            DeitY-TU visual face database, which is being created in the Biometrics Laboratory at the Department of Computer Science and Engineering of Tripura University (TU), India, under a project with a grant from the Department of Electronics and Information Technology (DeitY), Ministry of Communications and InformationTechnology,Government of India. It contains 524 individuals’ face images under a controlled environment. These individuals cover the different tribe and nontribe people of the northeastern states of India. The database contains a total of eight expressions, including neutral expression,closedeye,and six basic expressions; four different types of illumination variations; and images with glasses, and each of these variations are being clicked concurrently from five different angles to provide pose variations.

SAMEER-TU Dataset


            The SAMEER-TU Outdoor Database is being created in the Infrared Image Processing Laboratory of Department of Computer Science & Engineering of Tripura University (TU), India, under a project with grant from the Society of Applied Microwave Electronics Engineering & Research (SAMEER), R & D Lab of Dept. of Electronics & Information Technology (DeitY), Ministry of Communications & Information Technology, Government of India. The SAMEER-TU Outdoor database consists of around 5640 natural scenes images in different weather and illumination conditions, out of which 1020 images are captured in foggy condition, 250 images in poor illumination condition and 4370 images in normal condition. The images in outdoor environment are mainly influenced by two factors-Weather effect and Illumination effect. Weather effects normally occurs in presence of fog, mist, haze etc. which results in poor visibility due to which the degraded image lose the contrast and color fidelity of the scene. Based on visibility parameter obtained per hour from the meteorological department, the weather effect is classified into high dense Fog and Low dense Fog. While Illumination effect is normally caused due to the variation in intensity of sunlight in different times of the day. All those natural scene images are captured by NIKON D5100 and FLIR E60 in outdoor environment after 15 minutes interval from 6 am to 6 pm in alternate 5 days from the month of January to March of the year 2014. During capturing those images, the temperature ranges from 10 degree centigrade to 24 degree centigrade, humidity ranges from 95% to 100%, dew point ranges from 10 degree centigrade to 15 degree centigrade, wind speed ranges from 1mph to 3.5 mph and visibility ranges from 0 km to 1 km.
