Tracing the vasculature in microscopy images

This webpage allows you to use an image-processing algorithm to trace the vessels of the microvasculature that surrounds a tumour. The algorithm is fully automatic and uses a scale space approach to detect the most relevant vessels. The intensity of the image pixels is considered to be analogous to the topographical altitude on a map and then the vessels become the equivalent of a ridge. The scale space approach will apply filters to the image to successively blur it and thus erase detail in order to detect the ridges of different widths.

The algorithm description can be found in the paper:

You can upload an image of maximum size 2 Mb of the following formats (ONLY) TIFF, BMP, GIF, JPEG, or PNG. The name of the file must ONLY contain letters uppercase and lowercase (a-z, A-Z) and underscore (_). Any other characters such as -, +, %, ^ and blank spaces may create problems. A single dot can be used to distinguish the name of the file, from the extension (e.g. Image24_a.jpg is acceptable).
