according to its gradation distribution situation to have the different gradation distribution, possibly appeared 1 or many gradation peak values. basis peak value integer as well as the treating processes difference, was allowed to use different method to complete the gradation picture two values processes. picture two values is refers through establishes some threshold value, And take this threshold value as the threshold, has the multi- gradation level the picture inversion two gradation levels picture (namely black and white chart), namely all picture elements respectively set for black (picture element value are 0) and are white (picture element value are 1). the different threshold value hypothesis method have formed the different two values treating processes, commonly used two values processing had following several methods: (1) fixed threshold value law Regarding gradation picture collection F, is smaller than it was equal to (or is bigger than was equal to) some threshold value theta picture element F [ i ] [ j ] sets is 0; Is bigger than (or is smaller than) theta the picture element value all to install in parts is 1; Among them, the different picture is different according to the gradation distribution peak value may choose the different theta value. (2) the double fixed threshold value law Has the double peak value regarding the gradation distribution picture collection F, may establish 2 different threshold values theta 1 and theta 2 (theta 1
2 .divides the shape dimension computational procedure to design
FDCP the design to need to involve to the big memory allocation, the regression analysis, the multi- windows, data sharing and the position operation and so on many contents, therefore uses the object-oriented programming (OOP) Visual C++ is the relational schematic drawing. host which divides between the shape dimension computational procedure various functions module controls the module control entire procedure as the FDCP programming language. chart 4 the window frame to renovate, the news transmission and processing as well as each function sub- module linking up with the sub- window user area; The image display module responsibly completes in the sub- window user area demonstrated divides the shape picture as well as the computed result; The computation module includes 4 different computational methods the 毕业论文

http://www.751com.cn/the sub- module to halve the shape picture with different method the dimension to carry on the computation; The data exchange module mainly uses in with other Windows procedure or software carries on data exchange. this procedure to use 2 different method, namely uses the clipboard and the WMF picture document and the data file. use visible programming language Visual C++ basic kind of storehouse (Microsoft Foundation Class: MFC) carries on the programming, may fully use the C++ language object-oriented programming the merit, can enhance the code to carry out the efficiency, guaranteed the procedure is easy to expand, the maintenance, the transplant, the code compact, the efficiency higher merit, simultaneously fully used the Windows platform to support the multi- duties the characteristic, was easy to realize the different application procedure data exchange. other also to be allowed according to the need, to calculated the module to make the corresponding supplement, caused to increase the new computational method is easy. procedure to provide the extremely friendly user contact surface. chart 5 is FDCP had demonstrated 5 level of Koch curve main window contact surface. it had "File", "View", "Fractal", "Window" and "Help" and so on the menu as well as respective under pull the menu composition. among, the image display module uses MFC and the SDK mix programming, the procedure frame completes using MFC. but because MFC brings the CBitmap kind of demonstration speed is slower, for the acceleration image display process, uses MFC the frame to transfer the SDK function to realize the demonstration function. because this procedure needs to support the many pictures document simultaneous working, therefore the FDCP procedure must use the MDI window form to carry on the design. for the confirmation procedure reliability, Separately used the straight line, the square, the Koch curve, kantuo 3 point array this 4 kinds to have the gauge minute shape graphthe computed result to carry on the confirmation to FDCP. among, straight line, square and kantuo 3 point array divided the shape dimension computed result and the theory value strict is equal. calculates the 5th level of Koch curve minute shape dimension with the FDCP box math module, result like chart 6 has shown. may obtain from chart 6, FDCP the computation Koch tune line segment shape dimension was 1.2166. Koch curve theory minute shape dimension is DKoch = ln4/ln3 = 1.2619, but because the infinite level Koch curve was cannot result in, Therefore demarcates uses the 5th level of Koch curve, the computed result indicated FDCP used in to calculate divides Uygur is the reliable. literature [ 5 ~ 8 ] successfully the contact surface minute shape dimension which gradient function material existed to Mo/ beta '-Sialon and Ta/ beta in the '-Sialon has conducted the research with this article procedure. math has calculated chart with the FDCP procedure box 3 (c) the crystal dimension is 1.694; Chart 3 (d) a jinbian dimension is 1.388, result like chart 7 shows. thus it can be seen, the different research object constitutes the minute shape dimension is obviously different, therefore, must correctly select the research to divide the shape object and the choice appropriate computational method .
3. conclusion
union image analysis and the processing technology, use visible programming language Visual C++ designed (FDCP). the procedure had easy based on the Windows platform minute shape dimension computational procedure to maintain, Might the expansion good, the contact surface friendly, the time efficiency and the spatial efficiency high, data sharing is good and so on the merit. with the straight line, the square, the Koch curve, kantuo, 3 point array and so on has the gauge minute shape graph to carry on to FDCP has demarcated, finally indicated FDCP used in to calculate the minute shape dimension is reliable.
