Query: Recurrence quantification analysis as a post-processing technique in
  adaptive optics high-contrast imaging   In this work we explore the possibility of using Recurrence Quantification
Analysis (RQA) in astronomical high-contrast imaging to statistically
discriminate the signal of faint objects from speckle noise. To this end, we
tested RQA on a sequence of high frame rate (1 kHz) images acquired with the
SHARK-VIS forerunner at the Large Binocular Telescope. Our tests show promising
results in terms of detection contrasts at angular separations as small as $50$
mas, especially when RQA is applied to a very short sequence of data ($2$ s).
These results are discussed in light of possible science applications and with
respect to other techniques like, for example, Angular Differential Imaging and
Speckle-Free Imaging.
