Recent advances in automatic feature detection and classification of fruits including with a special emphasis on Watermelon (Citrillus lanatus): A review

This document provides an overview of advances in the task of automatic feature detection and classification of fruits, with and special interest in watermelon (Citrillus lanatus). The review was written with the objective to highlight the wealth of knowledge that exist in the application of analytical, smart and sensing image recognition techniques commonly used in agro-industry, and the computational approaches used to make the classification possible. Also, an specific interest is put in the contributions made in the development of automatic recognition systems geared towards for watermelon using images, acoustic and spectroscopy methodologies. The importance of this document is that it provides a conceptual summary of the methods for the automatic recognition of fruits, including machine learning and evolutionary computational algorithms to analyze their sensed data. In conclusion this is a first step into recognizing the challenges and opportunities that can be addressed in this field to augment the visibility of these methods and to further modernize the agro-industrial sector.
