Volume estimation of apple fruits using image processing

The present paper describes analytical methods for estimation of volume of axi-symmetric fruits like apples based on single view fruit images and the shape-based analytical models. The fruits are categorized into spherical, ellipsoid and paraboloid shapes with appropriate analytical models for their volume estimation. The methods analyze the single view fruit images to extract the eccentricity and shape related parameters and use appropriate shape models for estimating the volume. The proposed methods were tested in the laboratory and found to be reasonably accurate.
