摘要

Goal: We extend a classic signal processing algorithm, the lock-in amplifier, to two dimensions to extract the signal in patterned images. Methods: The algorithm was evaluated using simulated image data and experimental microscopy images to determine the fluorescence signal of fluorescently labeled proteins adsorbed on surfaces patterned with chemical vapor deposition. Results: The algorithm was c...
