Multi-resolution imaging is one of the key means to obtain the target scene information. The Hadamard matrix, which is orthogonal, is an important modulation matrix for single-pixel imaging. In particular, it can provide a good means for multi-resolution imaging. However, as far as we know, studies of high-efficiency multi-resolution single-pixel imaging are rare in the literature. In view of the practical application requirements of fast multi-resolution imaging, we propose a multi-resolution single-pixel imaging method based on Hadamard ‘pipeline’ coding, which can directly generate two-dimensional Hadamard basis patterns and multi-resolution Hadamard optimization sequences, whereby both the memory consumption and the complexity of coding implementation for multi-resolution imaging can be significantly reduced. The commonly used optimization method of Hadamard optimization sequence implementation and time consumption are also discussed. This method provides a new approach for Hadamard sequence optimization and multi-resolution single-pixel imaging applications.

通过Hadamard“管道”编码的多分辨率单像素成像

多分辨率成像是获取目标场景信息的关键手段之一。正交的Hadamard矩阵是单像素成像的重要调制矩阵。尤其是可以为多分辨率成像提供良好的手段。然而，据我们所知，关于高效多分辨率单像素成像的研究在文献中并不多见。针对快速多分辨率成像的实际应用需求，我们提出了一种基于Hadamard'pipeline'编码的多分辨率单像素成像方法，可以直接生成二维Hadamard基模式和多分辨率Hadamard优化序列，从而可以显着降低多分辨率成像的内存消耗和编码实现的复杂性。还讨论了Hadamard优化序列实现的常用优化方法和时间消耗。该方法为 Hadamard 序列优化和多分辨率单像素成像应用提供了一种新方法。
