 # Matthiola incana leaf dataset
+This dataset is intended to create a model for classifying images of Matthiola incana leaves into **single-flowered** leaf or **double-flowered leaf**.
+
+# Matthiola incana 
+Matthiola incana, a member of the family Brassicaceae, is an ornamental plant cultivated worldwide for its beautiful flowers. This species exhibits two flower forms: single and double flowers. The market for single-flowered plants is extremely limited and their commercial value is lower than that of double-flowered plants. Therefore, to efficiently produce high-value M. incana, farmers select double-flowered plants during the seedling stage, a few weeks after sowing, based on cotyledon characteristics. However, this identification is not simple and can be extremely difficult for inexperienced individuals.Using this dataset, you can create a classification model for Matthiola incana.
+
+# About the dataset
+It contains data on the following varieties of M. incana:
+
+* Quartet_Apricot
+* Quartet_Blue
+* Quartet_Marine
+* Quartet_Rose
+
+Although there are two existence folders for the same variety, such as Quartet_Apricot and Quartet_Apricot2, it is guaranteed that the M. incana contained in these folders are different individuals. To prevent data leakage, we recommend using either Quartet_Apricot or Quartet_Apricot2 as training data and the other as test data, and similarly for the other three varieties.
+
+Each folder is further divided by {date}_{single or double}.
+The purpose of this data is to perform binary classification between **single** and **double**.
