Direct imaging of exoplanets is limited by bright quasi-sta tic speckles in the point spread function (PSF) of the central star. This limitation can be reduced by subtract ion of reference PSF images. We have developed an algorithm to construct an optimized reference PSF image f rom a set of reference images. This image is built as a linear combination of the reference images availa ble nd the coefficients of the combination are optimized inside multiple subsections of the image indepen dently… 
A High-contrast Imaging Algorithm: Optimized Image Rotation and Subtraction
Image Rotation and Subtraction (IRS) is a high-contrast imaging technique which can be used to suppress the speckles noise and facilitate the direct detection of exoplanets. IRS is different from
Planet detection down to a few λ/D: an RSDI/TLOCI approach to PSF subtraction
TLDR
The results of work to optimize PSF subtraction with the GPIES reference library using a least-squares algorithm designed to minimize speckle noise and maximize planet throughput, thus maximizing the planet signal to noise ratio (SNR).
GPI PSF subtraction with TLOCI: the next evolution in exoplanet/disk high-contrast imaging
TLDR
A new algorithm, TLOCI (for Template LOCI), is designed to achieve this task by maximizing a companion signal-to-noise ratio instead of simply minimizing the noise as in the original LOCI algorithm, and has achieved impressive contrast.
Robustness to bad frames in angular differential imaging: a local weighting approach
Context. The detection of exoplanets by direct imaging is very challenging. It requires an extreme adaptive-optics (AO) system and a coronagraph as well as suitable observing strategies. In angular
SFADI: the Speckle-Free Angular Differential Imaging method
We present a new processing technique aimed at significantly improving the angular differential imaging method (ADI) in the context of high-contrast imaging of faint objects nearby bright stars in

We propose a data reduction approach called global optimization-based reference star differential imaging (G-RDI), which can be used for exoplanet imaging survey, where large numbers of target
Simultaneous exoplanet detection and instrument aberration retrieval in multispectral coronagraphic imaging
Context. High-contrast imaging for the detection and characterization of exoplanets relies on the instrument’s capability to block out the light of the host star. Some current post-processing methods
Improving Signal to Noise in the Direct Imaging of Exoplanets and Circumstellar Disks
We present a new algorithm designed to improve the signal to noise ratio (SNR) of point and extended source detections in direct imaging data. The novel part of our method is that it nds the linear
S4: A Spatial-Spectral model for Speckle Suppression
High dynamic-range imagers aim to block out or null light from a very bright primary star to make it possible to detect and measure far fainter companions; in real systems a small fraction of the
Optimization and application of a LOCI-type reduction pipeline to detect exoplanets
TLDR
A personalized version of LOCI (Locally Optimized Combination of Images) is implemented, based on the existing code of Dimitri, endeavoring algorithmic optimization of its parameters, computation of contrast curves taking into account the extinction of the companion by LOCI, and compilation of all the required steps of data reduction.
