Multi-frame image super-resolution (SR) is an image processing technology applicable to any digital, pixilated camera that is limited, by construction, to a certain number of pixels. The objective of SR is to utilize signal processing to overcome the physical limitation and emulate the “capabilities” of a camera with a higher-density pixel array. SR is well known to be an ill-posed problem and, consequently,...
Decreased HIV-specific CD8+ T cell proliferation is a hallmark of chronic infection, but the mechanisms of decline are unclear. We analyzed gene expression profiles from antigen-stimulated HIV-specific CD8+ T cells from patients with controlled and uncontrolled infection and identified caspase-8 as a correlate of dysfunctional CD8+ T cell proliferation. Caspase-8 activity was upregulated in HIV-specific...
This paper presents a computationally efficient method for the measurement of a dense image correspondence vector field using supplementary data from an inertial navigation sensor. The application is suited to airborne imaging systems (such as on a UAV) where size, weight, and power restrictions limit the amount of onboard processing available. The limited processing will typically exclude the use...
