Consultation

[Martín Matías Pérez Zanón]

Hi all,
Attached it’s a Jpg image that I take from a .avi video of a Eco Doppler from a cow ovary.
I need to measure the areas in colour (yellow-red) to know the proportion with de corpus luteus (dark gray draw with a brown line). Some one know how to do it and/or automatize the process or part of it?
Thank you very much.
Kind regards

Hello Martin,

We have a recent paper that may help you to design an automatic system:
http://bigwww.epfl.ch/publications/schorer1601.pdf
http://bigwww.epfl.ch/algorithms/blood-flow-monitoring/

It is seems that you do not have access the raw Doppler signal. In a such case you have only a “badly” compressed video signal, reverse engineering is required to recover the doppler velocity information! Need probably, correction on deblocking artefact, desinterlacing, denoising, retrieve the calibration (scale of Doppler), ...

Good luck!

Daniel
