  This paper presents a method for finding ram-pressure stripped (RPS) galaxy
candidates by performing a morphological analysis of galaxy images obtained
from the Legacy survey. We consider a sample of about 600 galaxies located in
different environments such as groups and clusters, tidally interacting pairs
and the field. The sample includes 160 RPS previously classified in the
literature into classes from J1 to J5, based on the increasing level of
disturbances. Our morphological analysis was done using the {\sc astromorphlib}
software followed by the inspection of diagnostic diagrams involving
combinations of different parameters like the asymmetry ($A$), concentration
($C$), S\'ersic index ($n$), and bulge strength parameters $F(G,\,M_{20})$.
  We found that some of those diagrams display a distinct region in which
galaxies classified as J3, J4 and J5 decouples from isolated galaxies. We call
this region as the morphological transition zone and we also found that tidally
interacting galaxies in pairs are predominant within this zone. Nevertheless,
after visually inspecting the objects in the morphological transition zone to
discard obvious contaminants, we ended up with 33 bonafide new RPS candidates
in the studied nearby groups and clusters (Hydra, Fornax, and CLoGS sample), of
which one-third show clear evidence of unwinding arms. Future works may
potentially further increase significantly the samples of known RPS using such
method.
