APPLICATION OF IMAGE PROCESSING FOR FROST DENSITY PREDICTION
RESUMO
A new non-contact method for frost density prediction is described. Successful results •were achieved when the Improved Digital Image Processing Method (IDIPM) was employed. It is based on the idea that the brightness of frost structure elements on an image is closely connected with their real 3-D positions. The brightest spots correspond to frost elements and belong to the front layer. If frost images are obtained under the same conditions, the porosity of the frost layer may be estimated after preliminary adjustment. Then, the frost density can be easily calculated from the known porosity. The possibility of continuous frost density measurements and the analysis of density distribution are advantages of the IDIPM.
