Abstract:

In this paper we present a correlation-based imaging technique in single pixel imaging scheme using Hadamard basis illumination. The Hadamard basis, which has the characteristics of a two bit value (−1, +1) and sparsity in its transformed domain, has been used in the illumination patterns and successfully utilized for imaging the incoherent target. It gives image reconstruction even in low light condition. Such deterministic pattern also helps to solve the problem of large number of measurements in single pixel imaging, and hence simplify the experimental implementation. Further to compare the quality of imaging with Hadamard basis patterns, we also compare imaging with Fourier basis patterns and simulation results of both methods, namely Hadamard and Fourier basis, are presented.

Keywords: Single pixel imaging, Hadamard basis patterns, Fourier basis patterns.

This paper presents an intriguing geometry dash unblocked approach to correlation-based imaging using Hadamard basis illumination in single pixel imaging. The utilization of Hadamard basis patterns offers advantages such as sparsity in the transformed domain and effective imaging of incoherent targets even in low light conditions. The comparison with Fourier basis patterns provides valuable insights into the quality of imaging achieved. Overall, this research contributes to advancing single pixel imaging techniques and offers potential simplifications in experimental implementation.
