WebbDespite the remarkable progress, most existing pan-sharpening methods only work in the spatial domain and rarely explore the potential solutions in the frequency domain. In this paper, we propose a novel pan-sharpening framework by adaptively learning low-high frequency information integration in the spatial and frequency dual domains. Webb3 apr. 2024 · Here is the high boost filter processing. The high boost filter, which is a sharpening filter, is just 1 + fraction * high pass filter. Note the high pass filter here is in created in the range 0 to 1 rather than 0 to 255 for ease of use and explanation.
