Invariant digital color correlation for the identification of worm parasites from bullseye pufferfish

摘要

The secure identification of parasites can be problematic and yet it is of prime importance. However, the specific identification of the parasites with traditional techniques can be slow and time consuming, requiring quality preparations where each taxonomically important structure can be clearly observed. Color information becomes an important discriminant feature, which we need to include in the whole identification process. Digital images of the monogeneans: Heterobothrium ecuadori and Neobenedenia melleni and, the digeneans Lintonium vibex, Homalometron longisinosum, Bianium plicitum and Phyllodistomum mirandai were processed to obtain their diffraction patterns. A numerical simulation was performed in order to correlate diffraction patterns of parasites species with phase only filters. The position, scale and rotation invariant image recognition was made through the scale transform.
