About

In this website are available the codes used to reproduce the analysis and results of the paper describing the pliman R package

pliman (plant image analysis) is designed to analyze plant images, especially related to leaf and grains. The package will help you to:

• Measure leaf area;
• Measure disease severity;
• Count the number of lesions;
• Obtain the shape of lesions;
• Produce Standard Area Diagrams;
• Count objects in an image;
• Get object features (area, perimeter, radius, circularity, eccentricity, solidity);
• Get the RGB values for each object in an image;
• Get the object coordinates;
• Get the object contours;
• Get convex hulls;
• Isolate objects;
• Plot object measures.

pliman also provides useful functions for operation, transformation, and segmentation of images. Please, visit the Examples page in pliman website for a detailed documentation of each function.
