  • Collaborative representation of convolutional neural network features to detect artificial ripening of banana using multispectral imaging 
    Vetrekar, N.T.; Prabhu, A.K.; Naik, A.; Ramachandra, R.; Raja, K.B.; Desai, A.R.; Gad, R.S. (Journal of Food Processing and Preservation. 46(10); 2022; ArticleID_e16882.)
    With the increasing demand for fruits in the consumer market and to fulfill the needs of consumers, fruits are deliberately resorted to ripen artificially using industrial-grade Calcium Carbide (CaC sub(2)) which has ...
  • Detection of artificially ripened banana using spectral signature from multi-spectral imaging 
    Vetrekar, N.T.; Ramachandra, R.; Raja, K.B.; Gad, R.S.; Naik, A.; Prabhu, A. (AIP Conference Proceedings. 2335(1); 2021; ArticleID_050001.)
    Ripening is a natural process of fruit maturation by which it attains desirable texture, aroma, colour and becomes more flavoursome. To meet the increasing needs of consumers, traders have resorted to artificial ripening ...
  • Multi-spectral imaging for robust ocular biometrics 
    Vetrekar, N.T.; Raja, K.B.; Ramachandra, R.; Gad, R.S.; Busch, C. (Proc. Int. Conf. on Biometrics, ICB-2018. 2018; 195-201.)
    Recent development of sensors has allowed to explore the possibility of biometric authentication beyond visible spectrum.Particularly, multi-spectral imaging has shown a great potential in biometrics to work robustly under ...
  • Multilevel fusion of multispectral images to detect the artificially ripened banana 
    Vetrekar, N.T.; Ramachandra, R.; Gad, R.S. (IEEE Sensors Letters. 7(1); 2023; ArticleID_7000404.)
    Automatic detection of artificially ripened fruits based on a nondestructive approach has recently gained significant attention. This work explores the inherent properties of multispectral imaging to distinguish between ...
  • Multispectral imaging for differential face morphing attack detection: A preliminary study 
    Ramachandra, R.; Venkatesh, S.; Damer, D.; Vetrekar, N.T.; Gad, R.S. (Proc. IEEE/CVF Winter Conference on Applications of Computer Vision (WACV). 2024; 6185-6193.)
    Face morphing attack detection is emerging as an increasingly challenging problem owing to advancements in high-quality and realistic morphing attack generation. Reliable detection of morphing attacks is essential because ...
