Tool for vessel branch segmentation by a dynamic image of fluorescent confocal microscopy. == Requirement ============================================= - Matlab with following toolbox (2011a or higher) - Image Processing Toolbox - Signal Processing Toolbox - Monitor (SXGA or higher) == Install ================================================= - Add all attached files to matlab path - Download "Better Skeletonization" tool from following URL and add to matlab path http://www.mathworks.com/matlabcentral/fileexchange/11123-better-skeletonization == Instruction =============================================== 1. Save time lapse images by tiff format in a directory. The alphabetical order of file name must correspond to the order of time frame. 2. Read Tiff format files in a directory and save it in a matlab file. >> imgData = VBSreadTiff('directory name'); Here, "imgData" is a structure of x,y,t image and the header of tiff. 3. Lounch VesselBranchSegmentation >> VesselBranchSegmentation 4. In Menu, Select "File > New", then select a saved matfile. 5. In Menu, Select "Estimation > Vessel Mask", then vessel region is extracted from vessels.(*) 6. In Menu, Select "Estimation > Vessel Class", then vessel region is classified into artery and vein.(*) This process takes a bit long time (~ 1 hour). 7. In Menu, Select "Estimation > Segmentation to Branches". New window appears and skeleton of artery mask is calculated. (**) Then press "To branch" button for segmentation to vessel branches. After closing the skeleton-shown window, repeat the same process for vein region. (*) The extracted mask can be modified by the edit tool. Turn "Editable checkbox" on to use the edit tool. See the document of impoly function for details. (**) The undesired skeleton will be calculated for low SNR images because of the ambiguous edge of vessel. The skeleton can be manually modified by the edit tool in the window.
