Study on the Feature Extraction Technology of the Asphalt Mix Image Based on Mathematical Morphology
The paper studied the feature extraction method of the asphalt mix digital image using the mathematics morphology. At first, the paper described the basic knowledge of the mathematics morphology. The basic algorithm of mathematics morphology was corrosion and dilation arithmetic. Based on the two arithmetic methods, the task expanded the open arithmetic and close arithmetic. The open arithmetic was run the dilation after corrosion, but the close arithmetic was reversed the order, that was the corrosion operation after dilation. In the study, the paper gave the particular dilation and corrosion arithmetic flow chat according to the characteristic of the asphalt mixture two-value image, and then gave the formula of the open operation and close operation. The task uses Delphi language to write the programming of the dilation, corrosion, open operation and close operation in dealing with the asphalt mixture two-value image. After careful analysis to the dealing effect, the study conclude that the close operation in which the dilation arithmetic is before the corrosion arithmetic has more practical meaning in extraction the parameters of the different grains in asphalt mixture.
