The optimal combination of size and shape parameters for classifying structural elements with the lowest percentage error is click here determined.For this purpose, logical sequences and a series of micrographs of tissues of the pumpkin Cucurbita pepo L.were used to identify and manually classify structural elements into three different classes: cells, intercellular spaces and unrecognizable elements.From each element, eight parameters of size and shape (area, equivalent diameter, major axis length, minor axis length, perimeter, roundness, elongation and compaction) were determined, and a logical sequence was developed to determine the combination of parameters that cashel tail bag generated the lowest error in the classification of the microstructural elements by comparison with manual classification.It was found by this process that the minimum error rate was 12.

7%, using the parameters of major axis, minor axis, perimeter and roundness.
