Adaptive Image Resolution

Adaptive image resolution is an engineering approach that changes an image’s spatial detail according to content, viewing conditions, or system requirements. Algorithms analyze image regions and operating constraints, then increase resolution where fine features or regions of interest matter while reducing it in less informative areas, often through resampling, tiling, or multiscale representations. This selective allocation of pixels and data can preserve important visual information while lowering storage, transmission bandwidth, processing time, or display demands. Applications include medical and scientific imaging, machine vision, remote sensing, video streaming, and resource-constrained devices, where efficient image handling supports faster analysis and responsive systems.

We describe a super-resolution imaging method to probe the structural organization of the bacterial FtsZ-ring, an essential apparatus for cell division. This method is based on quantitative analyses of photoactivated localization microscopy (PALM) images and can be applied to other bacterial cytoskeletal proteins.

We are developing a dynamic adaptive exposure technique using our scanning beam digital X-ray system. Rather than exposing an object uniformly, the exposure is adapted depending on the opacity of the object. Here we show an experiment on an anthropomorphic phantom that resulted in a dose saving of 30%.
