2Table of contents Astrocyte Structure Goals Segmentation and approaches.Our process.
3What is astrocyte?These are star-shaped glial cells in the brain and spinal cord.These are the most abundant cell of the human brain.Astrocytes are a sub-type of glial cells in the central nervous system.
5Goals: automatically segment Individual Glial Cells. intelligent thresholding.Segmentation.seed points classification.classify astrocytes and provide volume and surface area.
6Segmentationit is the process of partitioning a digital image into multiple segments.it is used to locate objects or their boundaries.
7Approaches to segmentation: Simple tresholding.Edge detection.Watershed transformation.Etc….
8Simple tresholding How To Choose The Value For The Threshold T ? By Visual Inspections Based On The Accurate Image Level The Treshold Can Be Applied.Does not require specific knowledge about the image.
9Edge detectionEdge Detection Extracts The Boundaries Of The Objects, Instead Of The Objects Themselves.Edge detection aims at identifying points in a digital image at which theimage brightness changes sharply or more formally has discontinuities.Discontinuities in image brightness are likely to correspond to:discontinuities in depthdiscontinuities in surface orientationchanges in material propertiesvariations in scene illumination
10Watershed transformation Watershed Segmentation Is An Approach Developed To Solve The Very Common Problem Of Separating Touching Objects.Segmentation Failed To Separate Too Close Objects
11OUR Process Segmentation Thresholding, edge detection, watershed transformation
