System and Method for Producing an Optically Sectioned Image Using Both Structured and Uniform Illumination |
摘要 |
A first image data set of the real-world object is received at a processor where the real-world object was illuminated with substantially uniform illumination. A second image data set of the real-world object is received at the processor where the real-world object was illuminated with substantially structured illumination. A high pass filter is applied to the first-image data set to remove out-of-focus content and retrieve high-frequency in-focus content. The local contrast of the second-image data set is determined producing a low resolution local contrast data set. The local contrast provides a low resolution estimate of the in-focus content in the first-image data set. A low pass filter is applied to the estimated low resolution in-focus data set, thus making its frequency information complementary to the high-frequency in-focus data set. The low and high frequency in-focus data sets are combined to produce an optically-sectioned data set of the real-world object. |
