Abstract:
1. An imaging for use with a processor for producing an optically-sectioned data set of a real-world object, the method comprising: receiving at the processor a first image data set of the real-world object that was illuminated with substantially uniform illumination; receiving at the processor a second image data set of the real-world object that was illuminated with substantially structured illumination; processing the first image data set producing a high-frequency in-focus data set; processing the second image data set producing a low-frequency in-focus data set; and combining the high frequency in-focus data set and the low-frequency in-focus data set to produce an optically-sectioned in-focus data set; wherein processing the first image data set includes: applying a high pass filter to the first-image data set to substantially remove out-of-focus content and obtain the high frequency in-focus image data set; and wherein processing the second image data set includes: determining local contrast of the second-image data set producing a low resolution local contrast data set; multiplying the low resolution local contrast data set with the first-image data set to extract low resolution in-focus content from the first-image data set.
