Here is the task1) finding the branch point (intersection) of the branches2) find the angle between the branches (there are 3 branches in total)I believe that the easiest way to find the branch point is using skeletonization and using the mask to find the branch point. I hope that everyone who want to help me to tell me what is the idea that you want to do to help me finding the best option. I attached the image of 3d branching structure as your sample.

Estimation of Phase Errors in SAR Data by Local-Quadratic Map-Drift Autofocus

Proceedings of 13th International Radar Symposium

We have developed an efficient autofocusing approach, which allows to retrieve an arbitrary phase error from radar data. This algorithm gives a possibility to use quite cheap GPS receiver for the aircraft trajectory measurement. Proposed LQMDA method is used for high-resolution imaging up to 0.5 meter resolution.

Range-Doppler Algorithm with Extended Number of Looks

Proceedings of the 2011 Microwaves, Radar and Remote Sensing Symposium

The Range-Doppler Algorithm (RDA) uses the Discrete Fourier Transform (DFT) for the efficient calculation of the convolution in the frequency domain. In the proposed method we extend the processed Doppler bandwidth in order to control real antenna beam deviation and nonuniform scene illumination.

Multi-Look Stripmap SAR Processing Algorithm with Built-In Correction of Geometric Distortions

Proceedings of the European Conference on Synthetic Aperture Radar (EuSAR'2010)

An efficient time-domain algorithm for synthetic aperture radar (SAR) is proposed. The advantage of given method is an improved multi-look processing scheme with possibility to obtain the radar image not in ''radar coordinates', but directly on the ground plane.
