Two near-infrared (NIR) pH-activated heptamethine indocyanine probes with quaternary ammonium unit were designed and synthesized. The absorption and emission titrations indicate that cationic structure improves the cyanine dye’s aqueous solubility and these two probes exhibit highly sensitive response to pH in acid condition. Their fluorescence intensities both gradually increase about 25-fold from...
Aiming at color remote sensing image with complexity, fuzziness and strong noise, an edge detection algorithm based on blocky fuzzy enhancement and multi-direction fuzzy mathematical morphology gradient is putted forward. It enhances the image by blocks in fuzzy domain, then employs fuzzy mathematical morphology gradient operation with multiple structure elements of different directions on the image...
