Visual Transformer for Object Detection

CoRR, 2022
Convolutional Neural networks (CNN) have been the first choice of paradigm in many computer vision applications. The convolution operation however has a significant weakness which is it only operates on a local neighborhood of pixels, thus it misses global information of the surrounding neighbors.

Rapid and reliable diagnosis of Moraxella catarrhalis infection using loop-mediated isothermal amplification-based testing

Frontiers in Bioengineering and Biotechnology
Moraxella catarrhalis (M. catarrhalis) was an important pathogen closely associated with respiratory tract infections. We employed the loop-mediated isothermal amplification (LAMP) coupled with nanoparticle-based lateral flow biosensor (LFB) and ...

Polarization Sensing with Visual Detection [PDF]

Analytical Chemistry, 1999
We describe a new approach to fluorescence sensing which relies on visual determination the polarization. The sensing device consists of a fluorescent probe, which changes intensity in responses to the analyte, and an oriented fluorescent film, which is not affected by the analyte.

Visualizing Object Detection Features [PDF]

International Journal of Computer Vision, 2016
We introduce algorithms to visualize feature spaces used by object detectors. Our method works by inverting a visual feature back to multiple natural images. We found that these visualizations allow us to analyze object detection systems in new ways and gain new insight into the detector's failures.
