Astrocyte Analysis Jing Mao
Goals • Extract, classify and count individual glial cells • Find seed points to start segmentation • Terminate segmentation for overlapping glial cells • Measure degree of astrocyte overlap with vessels in secondary channel • Percentage of total cell overlap • What part of the cell overlaps • Relate this to groupings of cells
Preprocess • Image-stack-tools-stack splitter • Split three channels
Preprocess Channel 1 Channel 2
Preprocess • Using existing plugin adaptive Thr • Extract features from background
Preprocess • Process-Noise-Despeckle • Analyze-Analyze Particles Channel 1 Channel 2
Analyze • Build plugin to compute the percentage of cell overlap 78 slices height width Channel 1 Channel 2
Analyze Channel 1 Channel 2
Two channels Total slices Width and height for each slice Total number of pixels with white in channel 1 and 2 Overlap in channel 1 and channel 2 Mark overlap area to red
Results Cell Overlap in Channel 1
