ABSTRACT
For an image, texture unit (TU) is a small complete unit which
characterizes the local texture of a given pixel and its neigh-
borhood. Recently, TU-based approaches have been widely
used in face recognition. This paper proposes a novel face
representation and recognition approach based on TU. We
make three major contributions: (1) we introduce a novel TU
feature, Local Gabor Quarternary Pattern (LGQP), which in-
corporates both Gabor magnitude and phase information in a
single TU code; (2) similarity measure of two TU images is
treated as a tracking problem between two images, and we
present a novel point-to-point matching (PPM) approach for
TU similarity measure; (3) based on an integral histogram
