英文摘要Binary Fourier single-pixel imaging (FSI) accelerates image acquisition by binarizing Fourier basis patterns. However, the use of the conventional Floyd-Steinberg error diffusion kernel introduces substantial quantization errors during binarization. Existing methods reduce quantization errors by employing upsampling prior to dithering but sacrifice spatial resolution. Notably, we observe that quantization errors are highly sensitive to the kernel parameters. To address this, we report a physics-informed global optimization framework that minimizes the L-2-norm discrepancy between the reconstructed and ground-truth Fourier spectrum. By iteratively evolving kernel parameters with a genetic algorithm, this framework yields globally optimized error diffusion kernels specifically tailored for FSI. Specifically, the Fourier basis patterns are partitioned into low-frequency and high-frequency regions, with distinct dithering kernels optimized for each domain. Our frequency-partitioned evolutionary dithering method significantly reduces quantization errors without compromising spatial resolution. Experimental validation demonstrates the method's efficacy: the structural similarity index value of reconstructed images (256 x 256 pixels) improves from 0.628 to 0.895, a 43% enhancement compared to the conventional method. This advancement drives the practical application of FSI in both online and high-quality imaging scenarios. (c) 2025 Author(s).
