Budidng Yeast data can be downloaded here, which includes 120 images. The corresponding project file can be downloaded here. |
Step 1: Preprocessing Action: The images are first loaded into CellTracer and then zoomed in to focus mainly on cell clusters. It is then cropped using the "Crop images to current view" tool in "Edit" menu. Purpose: Cropping will generally reduce the size of input images thus reduce the image analysis processing time. Paramenters: None. Result: All cropped images can be found here. As an example, the preprocessed result for image 120 is showing bellow. |

Three examples are included here to demostrate image segmentation and tracking using CellTracer.
All examples share similar workflows although different algorithms are used during cell segmentation.
It is possible to have one workflow with different parameter settings to apply to all examples,
but at the expense of more computing time. |
