Dry Beans Dataset
Description
A subsample of the Koklu & Ozkan (2020) dry beans dataset produced by imaging a total of 13,611 grains from 7 varieties of dry beans. The original dataset contains 13,611 observations, but here we include a random subsample of 1000.
Usage
minibeans
Format
minibeans
A data frame with 1000 rows and 17 columns:
- Area
The area of a bean zone and the number of pixels within its boundaries.
- Perimeter
Bean circumference is defined as the length of its border.
- Major axis length
The distance between the ends of the longest line that can be drawn from a bean.
- Minor axis length
The longest line that can be drawn from the bean while standing perpendicular to the main axis.
- Aspect ratio
Defines the relationship between L and l.
- Eccentricity
Eccentricity of the ellipse having the same moments as the region.
- Convex area
Number of pixels in the smallest convex polygon that can contain the area of a bean seed.
- Equivalent diameter
The diameter of a circle having the same area as a bean seed area.
- Extent
The ratio of the pixels in the bounding box to the bean area.
- Solidity
Also known as convexity. The ratio of the pixels in the convex shell to those found in beans.
- Roundness
Calculated with the following formula: (4piA)/(P^2).
- Compactness
Measures the roundness of an object: Ed/L.
- ShapeFactor1
Shape factor 1.
- ShapeFactor2
Shape factor 2.
- ShapeFactor3
Shape factor 3.
- ShapeFactor4
Shape factor 4.
- Class
Seker, Barbunya, Bombay, Cali, Dermosan, Horoz, and Sira.
