摘要
Single-pixel imaging requires a large amount of sampling. In this study, an adaptive Radon single-pixel imaging method is proposed for the target region that only occupies a part of the scene. This method uses single-pixel detectors to position and image the target region. We used the target positioning method, coding sampling, and reconstruction algorithms to reduce the number of single-pixel imaging samples. Based on the fundamental principle of Radon transformation, the projection information of an image in horizontal and vertical directions was used to obtain the size and position of the target region in the scene. This method established the adaptive Radon-Hadamard single-pixel imaging model. Only single-pixel sampling was performed on the target region and filtered back-projection technology was used to reconstruct the target region. The results show that the proposed adaptive Radon single-pixel imaging method can achieve imaging of the target region in a scene. The number of samples was much lower than the resolution of the reconstructed image and the structural similarity index of the reconstructed image was greater than 95%, which effectively improved the imaging efficiency of single-pixel imaging method. © 2021, Science Press.
