Abstract: According to one exemplary method, the method includes classifying image pixels in each video image of a series of video images as either foreground or background. The method also includes replacing each pixel classified as background with a time-averaged value of pixel intensity for that pixel. The method further includes compressing the video images using a compression algorithm.

Abstract: Methods, systems, and non-transitory computer readable media for reconstructing electronic images using blurring and noise-enhanced pixel intensity resampling are disclosed. One method includes, at an image reconstructor including at least one processor, receiving an image compressed using an image compression algorithm. The method further includes decompressing the image using an image decompression algorithm. The method further includes modifying pixel intensities in the image by blurring and/or resampling the pixel intensities according to a noise distribution generated by the reconstructor without receiving a noise estimate from an image compressor. The method further includes outputting the image with the modified pixel intensities.

Abstract: Methods, systems, and computer readable media for determining physical properties of a specimen in a portable point of care device are disclosed. According to one aspect, a method includes placing a specimen onto an active surface that includes a plurality of microposts extending outwards from a substrate, wherein each micropost includes a proximal end attached to the substrate and a distal end opposite the proximal end and generating an actuation force in proximity to the micropost array that compels at least some of the microposts to exhibit motion. The method further includes detecting light that is emitted by an illumination source and interacts with the active surface while the at least some microposts exhibit motion in response to the actuation force, measuring data that represents the detected light interacting with the active surface, and determining at least one physical property of the specimen based on the measured data.
