  Recently a coherent optical process called plasmon injection ($\Pi$) scheme,
which employs an auxiliary source, has been introduced as a new technique to
compensate losses in metamaterials. In this work, a physical implementation of
the $\Pi$ scheme on a thin silver film is proposed for enhanced superlens
imaging. The efficacy of the scheme is illustrated by enhancing near-field
imaging deeper beyond the diffraction limit in the presence of absorption
losses and noise. The auxiliary source is constructed by a high-intensity
illumination of the superlens integrated with a near-field spatial filter. The
integrated system enables reconstruction of an object previously unresolvable
with the superlens alone. This work elevates the viability of the $\Pi$ scheme
as a strong candidate for loss compensation in near-field imaging systems
without requiring non-linear effects or gain medium.
