A Review of Ghost Imaging via Sparsity Constraints
Applied Sciences, 2018 Different from conventional imaging methods, which are based on the first-order field correlation, ghost imaging (GI) obtains the image information through high-order mutual-correlation of light fields from two paths with an object appearing in only one ...
