It is a dataset for ten algae species (Chlamydomonas, Cladophora, Nostoc, Oedogonium, Oscillatoria, Pithophora, Spirogyra, Ulothrix, Vaucheria, and Volvox). It has been created for building classification model for automatic identification. Following are the features along with their descriptions which are extracted from the microscopic images of the algae. 1. Solidity: It is the ratio of area of an object to the area of a convex hull of the object. Computed as Area/ConvexArea. 2. Eccentricity: The eccentricity is the ratio of length of major to minor axis of an object. 3. EquivDiameter: Diameter of a circle with the same area as the region. 4. Extrema: Extrema points in the region. The format of the vector is [top-left top-right righ...
