Vessel branch segmentation 1.0

Segment the vessel branches from dynamic image of fluorescent microscopy== Install ======- Add all attached files to matlab path- Download "Better Skeletonization" 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>> VesselBranchSegmentation4. 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.
