Abstract

This work compares two prominent pattern recognition techniques, Random Forests (RF) and Support Vector Machines (SVM) on the problem of identifying the stem and/or calyx region of Jonagold apples. This work demonstrates the inherit feature selection characteristics of the RF algorithm that drives its performance to rival a feature-tuned SVM. Although the SVM slightly outperforms the RF algorithm in classification status, more information about the data can be acquired through RF methodology.
