Use of two-dimensional matched filters for estimating a length of blood vessels newly created in angiogenesis process

The complex algorithm for estimating a length of blood vessels' newly created in angiogenesis process has been presented. A filtering method using two-dimensional matched filter is a fundamental process in the presented algorithm. For proper extraction of blood vessels' network more image processing techniques has been used including spatial low-pass filtering, binarisation, skeletonisation, and, developed by the author, algorithms for cleaning vessel network obtained in this process and for removing vessels false detected in the previous steps. The presented algorithm can be used for fully automatic vessels' length estimating in medical images and can be helpful for angiogenesis process's research.
