This work proposes an approach for wavelet-refinement-inspired diffusion model for scattering imaging. A full-frequency component diffusion model is utilized to extract priori information of global distribution, while a high-frequency component diffusion model is utilized to acquire priori information about the details of the target. In the reconstruction process, the trained models provide multi-scale constraints in iterations of reconstruction, with the physics-based deconvolution providing fidelity. The results indicate that this work outperforms traditional methods in the reconstruction of complex targets while exhibits robust generalization capabilities. Simulation and experimental validation show that the proposed method can effectively remove the gridding artifacts in the reconstructed images for complex targets.

Defects are achieved by opening different numbers of square holes at different locations at the unit cell interior. Based on Bloch’s theorem, the propagation wave behavior of the bi-material nested structure with defects is discussed using the finite element method (FEM). The effects of the number of square holes, the location of defects, the shape of nested lattice and the density of filled metal materials on the band gap distribution are studied. In order to verify the existence of band gap, low amplitude elastic wave propagation experiment is made by 3D printing technology. The results show that non-overlapping band gaps appear in the bi-material nested structure with defects within 1000 Hz by changing the defect position and the number of square holes, and the switching control effect of frequency 500–1000 Hz band gaps is realized. The effect of filler metal density on the band gap is discussed on the basis of I-type phononic crystal structure, which provides design support for the application requirements of different working conditions. When the surface area of filled metal material is 52 % of the total surface area, circular nested phononic crystal band gap modulation works best. The experimental and simulation results are consistent to verify the existence of band gap.

However, the subtle morphological differences among various WBC types pose challenges to accurate classification, even for experienced experts. Deep learning has emerged as a powerful tool to enhance optical microscopic imaging in WBC classification. Therefore, this study proposes a novel convolutional neural network with neuron-position correlation attention (NPCA) named NPCA-wbcNet to overcome this challenge of WBC classification. Specifically, the NPCA could effectively generate 3D weights to infer the discrimination and importance of each neuron and establish interactive relationships between different locations and channels, thereby highlighting the location and shape of the target category in the image and enhancing the identification of fine-grained features. Additionally, we replace some regular convolutions with partial convolutions, which makes the model more lightweight and achieves better results in extracting spatial features. We evaluate the performance of our model on DrlWBCs, a new dataset of 24,713 blood smear images with five WBC subtypes. The model achieved an accuracy of 98.46 % for WBC classification, and the acute lymphoblastic leukemia (ALL) diagnostic accuracy on the ALL-IDB2 dataset was 98.08 %.

Its core idea is to use a single-pixel detector, which lacks spatial resolution, to acquire high-dimensional scene information through light field modulation and algorithmic reconstruction. However, the fixed arrangement of traditional modulation matrices can introduce redundant features, limiting sampling efficiency and image quality. To address this issue, this paper proposes an optimized modulation matrix—the Convolution Matrix (CM). This matrix replaces the traditional modulation matrix by utilizing its local correlation properties, capturing target information and texture features through convolution, thus reducing redundant information encoding. In addition, a Feature Reconstruction Single-Pixel Imaging Network (FRSPINet) is designed, which integrates an efficient multi-scale attention mechanism. It optimizes high-frequency detail reconstruction by channel-space interactive weight allocation, addressing image degradation issues at low sampling rates. Experimental results show that at a 10 % sampling rate, FRSPINet with the convolution matrix achieves Structural Similarity Index (SSIM) values of 98.1 % and 92.2 % on the MNIST and Fashion MNIST datasets, respectively. On the TFI dataset, the SSIM value is 93.2 %. In practical tests on mini-digits and mini-fashion datasets, the SSIM values between under-sampled and full-sampled reconstructed images are 94.5 % and 87.8 %, respectively.
