Secondary complementary balancing compressive imaging with a free-space balanced amplified photodetector
Wen-Kai Yu, Ying Yang, Jin-Rui Liu +2
Single-pixel imaging (SPI) has attracted widespread attention because it generally uses a non-pixelated photodetector and a digital micromirror device (DMD) to acquire the object i…
Single-pixel imaging based on weight sort of the Hadamard basis
Wen-Kai Yu, Chong Cao, Ying Yang +3
Single-pixel imaging (SPI) is very popular in subsampling applications, but the random measurement matrices it typically uses will lead to measurement blindness as well as difficul…
