Sažetak
A better reconstruction algorithm, a better measurement matrix, and a better denoising algorithm can all improve the signal reconstruction quality of compressive sensing. The operator matrix of a single-pixel camera has little effect on the noise in the measurement data and can improve the performance of the measurement matrix. The operator matrix can improve both the signal reconstruction quality and the reconstruction calculation speed for single-pixel camera images. Although a better reconstruction algorithm can improve the quality or speed of signal reconstruction, the operator matrix can improve the performance of the reconstruction algorithm fundamentally. The operator matrix can make reconstruction algorithms get better reconstruction ability. Moreover, the operator matrix is a universal method for improving compressive sensing.
