  The high contrast and spatial resolution requirements for directly imaging
exoplanets requires effective coordination of wavefront control, coronagraphy,
observation techniques, and post-processing algorithms. However, even with this
suite of tools, identifying and retrieving exoplanet signals embedded in
resolved scattered light regions can be extremely challenging due to the
increased noise from scattered light off the circumstellar disk and the
potential misinterpretation of the true nature of the detected signal. This
issue pertains not only to imaging terrestrial planets in habitable zones
within zodiacal and exozodiacal emission but also to young planets embedded in
circumstellar, transitional, and debris disks. This is particularly true for
H{\alpha} detection of exoplanets in transitional disks. This work delves into
recent H{\alpha} observations of three transitional disks systems with MagAO-X,
an extreme adaptive optics system for the 6.5-meter Magellan Clay telescope. We
employed angular differential imaging (ADI) and simultaneous spectral
differential imaging (SSDI) in combination with KLIP, a PCA algorithm in
post-processing, for optimal starlight suppression and quasi-static noise
removal. We discuss the challenges in protoplanet identification with MagAO-X
in environments rich with scattered and reflected light from disk structures
and explore a potential solution for removing noise contributions from real
astronomical objects with current observation and post-processing techniques.
