  We present a catalog of 5437 morphologically classified sources in the
direction of the Perseus galaxy cluster core, among them 496 early-type
low-mass galaxy candidates. The catalog is primarily based on V-band imaging
data acquired with the William Herschel Telescope, which we used to conduct
automated source detection and to derive photometry. We additionally reduced
archival Subaru multiband imaging data in order to measure aperture colors and
to perform a morphological classification, benefiting from 0.5 arcsec seeing
conditions in the r-band data. Based on morphological and color properties, we
extracted a sample of early-type low-mass galaxy candidates with absolute
V-band magnitudes in the range of -10 to -20 mag. In the color-magnitude
diagram the galaxies are located where the red sequence for early-type cluster
galaxies is expected, and they lie on the literature relation between absolute
magnitude and S\'{e}rsic index. We classified the early-type dwarf candidates
into nucleated and nonnucleated galaxies. For the faint candidates, we found a
trend of increasing nucleation fraction toward brighter luminosity or higher
surface brightness, similar to what is observed in other nearby galaxy
clusters. We morphologically classified the remaining sources as likely
background elliptical galaxies, late-type galaxies, edge-on disk galaxies, and
likely merging systems and discussed the expected contamination fraction
through non-early-type cluster galaxies in the magnitude-size surface
brightness parameter space. Our catalog reaches its 50 per cent completeness
limit at an absolute V-band luminosity of -12 mag and a V-band surface
brightness of 26 mag arcsec$^{-2}$. This makes it to the largest and deepest
catalog with coherent coverage compared to previous imaging studies of the
Perseus cluster.
