Divides the shape algorithm the analysis and the design
Has studied the minute shape picture analysis process, proposed the reasonable minute shape picture withdrew the flow. to complete using Visual C++ based on the Windows platform minute shape dimension computational procedure (Fractal Dimension Calculation Program: FDCP) the design, and by the straight line, kantuo, 3 point array, the Koch curve division shape graph carried on to it has demarcated.
Divides the shape theory [ 1 ~ 4 ] the widespread application relies on to is divided the shape picture a minute shape which withdraws, processing and in the minute shape dimension computation. reality exists nearly all is the random minute shape, its dimension computation has a gauge minute shape the dimension to be much more complex than, moreover has many different computational methods, they all need to carry on the massive image analysis and the statistical operation. therefore the establishment computer program completes work and so on image analysis, processing and minute shape dimension computation is solution above question effective means. Visual C++ is at present most popular programming language, It has the object-oriented programming, supports Windows all characteristics, the probability is good and so on merit. this article uses Visual the C++ design based on Windows the platform FDCP procedure.
1. minute shape image analysis
materials science domain many processes all have the massive random minute shapes, like the material break, the liquid metal coagulation, the thin film 毕业论文http://www.youerw.com/ 论文网http://www.youerw.com/, picture, SEM and TEM appearance likes and so on) generally all is the simulated signal, must first complete the digitized process, then does other the information to remove, thus withdraws the minute shape graph. obviously, this is a very complex process. minute shape graph withdraws the flow like chart 1 to show. first obtains the material test specimen the appearance picture, As primitive picture; Using equipment and so on scanner primitive SEM (or TEM and so on) the appearance picture will input in the computer and by the certain gradation picture document format (for example: TIFF, BMP, PCX) preserves; After removes the noise signal, carries on careful processing to the picture enable the picture to have the appropriate contrast gradient; Carries on the minute shape characteristic under the best contrast gradient condition withdrawing, obtains the corresponding minute shape picture (or graph). because the Windows operating system is widely used, the BMP picture form obtains nearly possesses based on the Windows platform picture software support, therefore the minute shape image analysis procedure uses the BMP form to carry on the data storage, moreover general picture processing software generally all can complete between the different picture form the transformation. BMP form picture document to be composed by 3 parts: Position chart article article (BITMAPFILEHEADER) construction of data, position chart information (BITMAPINFO) construction of data and position chart array information. analysis position chart article article after position chart information construction of data, can correctly use in the position chart array the information. minute shape image analysis to use Visual with the minute Uygur computational procedure the C++ language programming, take Windows as the working platform. position chart array information has recorded the picture each picture element value. when the production picture, Windows from the picture left under angle starts by scanline the picture, namely from to is left right, from under to on, 11 recorded. these bytes the picture picture element value to compose the position chart array information, its recording order like chart 2 showed. the minute shape picture primitive picture generally all is the gradation picture (colored picture may process gradation picture), divided the shape characteristic to withdraw mainly is judges. the different picture 1274
