摘要翻译：
单像素成像(SPI)的一个主要缺点是需要多次连续光照来捕获单个图像，且捕获时间长。傅里叶模式和阿达玛模式等基光照模式比随机模式具有更好的成像效率。但是，由于基模式是固定的，并且对不同的目标图像不自适应，所以该算法的性能仍然不理想。提出了一种基于主成分分析(PCA)的图像特征自适应设计和优化光照模式的新方法。仿真和实验结果表明，我们提出的方案在成像效率方面优于传统的傅里叶SPI。

英文摘要：
Single-pixel imaging (SPI) has a major drawback that many sequential illuminations are required for capturing one single image with long acquisition time. Basis illumination patterns such as Fourier patterns and Hadamard patterns can achieve much better imaging efficiency than random patterns. But the performance is still sub-optimal since the basis patterns are fixed and non-adaptive for varying object images. This Letter proposes a novel scheme for designing and optimizing the illumination patterns adaptively from an image dictionary by extracting the common image features using principal component analysis (PCA). Simulation and experimental results reveal that our proposed scheme outperforms conventional Fourier SPI in terms of imaging efficiency.
