Enhanced Corrosion Detection By Means of Multispectral Imaging and Postprocessing Techniques

Giegerich W.V., Fedorishin D.C., Forte III L., Christie L., Schneider P.J., Oh K.W., University at Buffalo, US

This research focuses on the implementation of an enhanced corrosion detection algorithm using multispectral imaging techniques and post-processing image filters. Utilizing various combinations of light filters with image enhancement software, we are able to increase [...]

Additive Manufacturing of 3D Face Masks for Biometric Spoofing

Christie L., Mancuso K., Fedorishin D., Schneider P., Stone A., Oh K., University at Buffalo, US

Biometric security systems such as Apple’s FaceID have replaced passwords for mobile device security, leav- ing users susceptible to biometric spoofing attacks. In response, Apple has implemented an anti-spoofing scheme, looking for autonomous ocular movement [...]

Post-Processing Effects on 3D Dynamic Models Created from Additive Manufacturing

Fedorishin D., Stone A., Eadie N., Christie L., Schneider P., Oh K., University at Buffalo, US

Recent advancements in 3D printing have made it a more viable option for rapid and inexpensive modeling of three dimensional (3D) dynamic systems. This shift in modeling techniques comes with inherent issues. The rough finish [...]

Microfluidic Test Target for Photoacoustic Imaging

Schneider P., Eadie N., Christie L., Zhan Y., Siskar T., Koh D., Xia J., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Photoacoustic imaging involves the use of optics (typically a high power pulsed laser) and acoustics (ultrasonics frequency ranges >1MHz) to image a targeted object. Individually, these modalities, being optical and ultrasonic imaging, can be quantified [...]

Additive Manufacturing of Microfluidic Components via Wax Extrusion

Schneider P., Sukhotskiy V., Christie L., Siskar T., Karampelas I.H., Furlani E.P., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Fused deposition modelling (FDM) has been extensively applied in the fields of rapid prototyping and 3D printing, but typically this technique has mostly been used for the fabrication of low melting point plastics. This paper [...]
