✦ Synopsis

An accurate method was developed, using image analysis, for measurement of the length width and shape of cucumber fruits. Determination of the local width along the mid-line of the fruit, enabled a condensed description of the fruit to be given. From this condensed description, size and shape features can be extracted, such as length, width and neck-shape of cucumber fruits. Tests showed that the image analysis method was effective and efficient for determining shape features which are visually difficult to score. Comparison with the manually obtained results showed that the measurement errors for image analysis were much lower than the ones made by the observer, e.g. the standard deviation of cucumber length was 1)4 mm with image analysis and 3)5 mm by manual measurement. The proposed method has more general applicability and may be of interest for studying the shape of other elongated symmetrical objects.
