Morphological Feature Extraction of Jabon’s Leaf Seedling Pathogen using Microscopic Image
Abstract: This research aims
to analyze morphological techniques for feature extraction of Jabon’s leaf seedling
pathogen using digital microscopic image. The kinds of the pathogen were
Curvularia sp., Colletotrichum sp., and Fusarium sp.. Pathogens or causes of
disease were identified manually based on macroscopic and microscopic
observation of morphological characters. Morphological characters describe the
characteristics of shape, color and size of a pathogen structure. We focused on
shape feature by using the morphological techniques to feature extraction. The
morphology features extraction used were area, perimeter, convex area, convex
perimeter, compactness, solidity, convexity, and roundness. The methodologies
were acquisition, preprocessing, features extraction and data analysis for
derivative features. With features extraction, we got the pattern that
described each pathogen for pathogen identification. From the experimental
result showed that compactness and roundness feature were able to differentiate
each pathogen due to that the characteristics of each pathogen class were
separated.
