Segmentation of pathological osteocytes present in an undecalcified piece of bone from mice using Amira2D

This is a workflow to segment out osteocytes present in mouse bone sample using Amira2D

ImageOsteocytes

This Amira2D workflow segments out osteocytes present in mouse bone sample. The sample was acquired using a transmission electron microscope at 200kV and a magnification of 13.500x.

The image processing challenge was to isolate the osteocytes from the multitude of other cellular structures present in the sample. Simple thresholding would not suffice as all the cellular structures are at similar grayscale intensities

To overcome the challenge, the image was first denoised and then a structure enhancing module was applied to isolate the elongated osteocytes. Then a thresholding was applied and the unwanted noise was removed. Finally the osteocytes were labelled as separate structures and can be used for further analysis
