Spatial frequency domain I explained in Image structure, on page 75, how a one-dimensional waveform in time transforms to a one-dimensional frequency spectrum. This concept can be extended to two dimensions: The two dimensions of space can be transformed into two-dimensional spatial frequency. The...

To implement frequency and spatial dual guidance, we delicately develop two core designs: amplitude guided phase module in the frequency domain and global guided local module in the spatial domain. Specifically, the former processes the global frequency information via deep Fourier transform and ...
Subsequently, the spatial frequency domain imaging technique is used to obtain the sub-surface images of soybean seeds in a forward manner, and the optical coefficients such as the reduced scattering coefficient μ′s and absorption coefficient μa of soybean seeds are inverted. Finally, RL-MLR, ...
Enabled by the proposed method, we also demonstrate kHz high-speed dual-wavelength monitoring of wide-field optical properties of a highly dynamic flow field. To the best of our knowledge, this is the first demonstration of label-free non-contact imaging of quantitative optical properties of ...

First, an adaptive luminance equalization is implemented in the spatial domain to reduce radiometric variations, instead of removing all illumination components. Second, a frequency domain analysis-based feature-enhancement model is proposed to enhance image features while preserving image naturalness and ...
