Differentiation Among Lettuce (L. Sativa) Seed Varieties Grown In Gourmet Farms, Silang Cavite, Philippines Using Image Processing With Fuzzy Logic And Knn As Classifiers

摘要

Lettuce is one of the most widely used vegetable crops in our diet. We consume lettuce as a base for salads, on sandwiches and burgers to add texture and even as a garnish to decorate trays of food at parties. The crop comprises seven main groups of cultivars differing phenotypically. The difference between lettuce varieties is often determined by inspection of the leaves, which is time-consuming, subjective and prone to error. In this study, three lettuce cultivars: Cos or Romaine, Iceberg, and Latin lettuce are classified using its seeds by image processing. Using Fuzzy Logic and KNN as classifiers, the cultivars are differentiated according to three morphological features: area, perimeter and equivalent diameter from 216 training images and 72 testing images. The study is supposed to be beneficial to lettuce breeders and farmers as it provides a new way to classify lettuce by its seeds. Understanding the different classes of seeds has great significance as it helps in choosing the right seeds for farming.
