Illustration of the redundancy between the existing plant image analysis software solutions. Illustration of the redundancy between the existing plant image analysis software solutions, here for the analysis of single leaves. A. Properties of each software (measurements, license, operating system and automation level). B. Clustering of the different tools, based on their properties. A higher weight was given to the measurements compared to the other properties for the clustering (2:1). Tools designed for specific measurements (disease, venation analysis or species recognition) are highlighted in colors. For both figures, and for the sake of clarity, measurements were pooled by classes (e.g. size encompasses surface, length, width and perimeter measurements).
