RGBT Tracking via Multi-Adapter Network with Hierarchical Divergence Loss.

IEEE Trans Image Process 2021 Jun 14;PP. Epub 2021 Jun 14.

RGBT tracking has attracted increasing attention since RGB and thermal infrared data have strong complementary advantages, which could make trackers all-day and all-weather work. Existing works usually focus on extracting modality-shared or modality-specific information, but the potentials of these two cues are not well explored and exploited in RGBT tracking. In this paper, we propose a novel multi-adapter network to jointly perform modality-shared, modality-specific and instance-aware target representation learning for RGBT tracking. Read More

Autoantibody Discovery, Assay Development and Adoption: Death Valley, the Sea of Survival and Beyond.

Front Immunol 2021 27;12:679613. Epub 2021 May 27.

Research and Development, Inova Diagnostics, San Diego, CA, United States.

Dating to the discovery of the Lupus Erythematosus (LE) cell in 1948, there has been a dramatic growth in the discovery of unique autoantibodies and their cognate targets, all of which has led to the availability and use of autoantibody testing for a broad spectrum of autoimmune diseases. Most studies of the sensitivity, specificity, commutability, and harmonization of autoantibody testing have focused on widely available, commercially developed and agency-certified autoantibody kits. However, this is only a small part of the spectrum of autoantibody tests that are provided through laboratories world-wide. Read More
