Medical images provide significant diagnostic information for medical staff under the clinical environment. In the past,
with further manual analysis and diagnosis by doctors in person, patients’ conditions and diseases could be identified.
However, that is subjective and the result may differ from one doctor to another and even for the same doctor leading towards
both inter and intra inconsistencies. This paper introduces an algorithm capable of automatically analyzing the features of
collagen fibers within Second Harmonic Generation virtual biopsy image captured from the epidermal and dermal layers of the
human skin. As required by medical doctors, crucial features of collagen fiber includes its density, thickness, and orientation
diversity, facilitating analytical and quantification procedures for skin aging and pathologic diagnosis. Based on pathological
properties of collagen fibers, we established a Gabor filter bank including specific scales and clear directionality, which are
capable of accurately and quickly detecting different collagen fiber thickness and orientations. Moreover, our proposed
algorithm could also objectively quantify these detected features. With this computer-aided diagnosis, we are able to decrease
the time in feature extraction and expedite both diagnosis and hence treatment. Also, it saves the cost of adjusting hardware
instruments in extracting features. Comparing to relative work in literature, our algorithm provides a more comprehensive and
more accurate method in extracting features of collagen fibers providing high potentials in HGM image analysis.
