AI Article Synopsis
- The Fourier single-pixel imaging technique offers a promising approach for efficient imaging but can suffer from image quality issues, particularly ringing artifacts, when using low sampling ratios.
- To mitigate these problems, a new method called Vector guided Fourier single-pixel imaging (V-FSI) has been developed, focusing on extracting important high-frequency details through a customized sampling map.
- Experimental results show that V-FSI significantly improves image quality, especially for objects with distinct patterns and orientations, allowing for better detail perception and preservation.
Article Abstract
The Fourier single-pixel imaging technique exhibits great potential for compressive imaging. However, the utilization of low sampling ratio can introduce unwanted ringing artifacts, thereby compromising the fidelity of reconstructed image detail. To address this issue, Vector guided Fourier single-pixel imaging (V-FSI) has been proposed. We analyze the statistical properties in the edge vector field derived from images with low sampling ratio. Based on this information, a tailored sampling map is designed to acquire the significant high-frequency components for image reconstruction. Experimental results demonstrate the remarkable effectiveness of the proposed V-FSI method in enhancing image quality. Notably, V-FSI exhibits exceptional capabilities in perceiving and preserving the details of the objects, particularly for objects characterized by pronounced periodicity and directionality.
