Summary

    A microslicerimage data processing system (MSIPS) has been developed to observe the external appearance and internal structure as well as color distribution and also to obtain the quantitative information on the morphology of agricultural products having complex forms. From the performance tests using an broccoli as the sample to be measured, it was demonstrated that the MSIPS had the functions to reconstruct the 3dimensional image based on the image data of exposed cross sections obtained by multislicing of the sample with a thickness of 30 micro meter, and display the external appearance and the internal geometrical structure as well as color distribution of a arbitrary cross section of the sample choosing the free observation angles.
    A prediction method was proposed to determine the surface area as well as volume of an broccoli from the mass of it, based on the 2-dimensional quantitative information such as the periphery and area of exposed cross sections for the specimens separated from an broccoli. These results indicated that the MSIPS was a useful new system for the quantitative morphological measurement of agricultural products having the complex forms. It had been difficult to measure such quantities in the past.
