分叉和脊端點

Question

有沒有什麼方法通過使用Java代碼而不是Matlab等來在圖像（手，靜脈）中找到分叉點和脊端點？我可以通過Java的ImageJ庫來實現嗎？

Answer 1

您在Minutiae Extraction from Fingerprint Images中找到的科學描述。 一些算法在OpenCV中實現請參閱分段部分。

OpenCV庫可以使用JNI鏈接到java。

Answer 2

有一個ImageJ的插件，可以幫助你做到這一點：

AnalyzeSkeleton （爲源見here）

您可以提取分支點和端點與其SkeletonResult類的幫助。

Answer 3

非常感謝幫助我，我經歷了AnalyzeSkeleton並通過使用IJ得到了SekeletonResult Response的結果。爲此，我使用了IJ.run（imp，「Skeletonize」，「」）;

// Initialize AnalyzeSkeleton_ 
    AnalyzeSkeleton_ skel = new AnalyzeSkeleton_(); 
skel.calculateShortestPath = true; 
skel.setup("", imp); 

// Perform analysis in silent mode 
// (work on a copy of the ImagePlus if you don't want it displayed) 
// run(int pruneIndex, boolean pruneEnds, boolean shortPath, ImagePlus origIP, boolean silent, boolean verbose) 
SkeletonResult skelResult = skel.run(AnalyzeSkeleton_.NONE, false, true, null, true, false); 

// Read the results 
Object shortestPaths[] = skelResult.getShortestPathList().toArray(); 
double branchLengths[] = skelResult.getAverageBranchLength(); 
int branchNumbers[] = skelResult.getBranches(); 

long totalLength = 0; 
for (int i = 0; i < branchNumbers.length; i++) { 
    totalLength += branchNumbers[i] * branchLengths[i]; 
} 

double cumulativeLengthOfShortestPaths = 0; 
for (int i = 0; i < shortestPaths.length; i++) { 
    cumulativeLengthOfShortestPaths +=(Double)shortestPaths[i]; 
} 
    System.out.println("totalLength "+totalLength); 
    System.out.println("cumulativeLengthOfShortestPaths "+cumulativeLengthOfShortestPaths); 
System.out.println("getNumOfTrees "+skelResult.getNumOfTrees()); 
System.out.println("getAverageBranchLength "+skelResult.getAverageBranchLength().length); 
System.out.println("getBranches "+skelResult.getBranches().length); 
System.out.println("getEndPoints "+skelResult.getEndPoints().length); 
System.out.println("getGraph "+skelResult.getGraph().length); 
System.out.println("getJunctions "+skelResult.getJunctions().length); 
System.out.println("getJunctionVoxels "+skelResult.getJunctionVoxels().length); 
System.out.println("getListOfEndPoints "+skelResult.getListOfEndPoints().size()); 
System.out.println("getListOfJunctionVoxels "+skelResult.getListOfJunctionVoxels().size()); 
System.out.println("getMaximumBranchLength "+skelResult.getMaximumBranchLength().length); 
System.out.println("getNumberOfVoxels "+skelResult.getNumberOfVoxels().length); 
System.out.println("getQuadruples "+skelResult.getQuadruples().length); this method .but I am not able to find which method in Skeleton Result class returns bifuraction point could you please help me little more thanks Amar
