  • Patent number: 11748850
    Abstract: Embodiments relate to a super-resolution engine that converts a lower resolution input image into a higher resolution output image. The super-resolution engine includes a directional scaler, an enhancement processor, a feature detection processor, a blending logic circuit, and a neural network. The directional scaler generates directionally scaled image data by upscaling the input image. The enhancement processor generates enhanced image data by applying an example-based enhancement, a peaking filter, or some other type of non-neural network image processing scheme to the directionally scaled image data. The feature detection processor determines features indicating properties of portions of the directionally scaled image data. The neural network generates residual values defining differences between a target result of the super-resolution enhancement and the directionally scaled image data. The blending logic circuit blends the enhanced image data with the residual values according to the features.

  • Patent number: 11162951
    Abstract: Fluorescent labeling of proteins. In particular, membrane-impermeant fluorogenic chromophores being capable of binding reversibly a functional derivative of a Photoactive Yellow Protein (PYP), or a functional fragment thereof, for fluorescently labeling biological molecules of interest, preferably proteins of interest. Especially, 4-hydroxybenzylidene-rhodanine (HBR) analogs of formula (II) as membrane-impermeant fluorogenic chromophores.
