*This is a repost of my submitted post in User Forums. I hope this reaches to someone who is willing to help me. Sorry if i'm cluttering the forums. *

So I'm currently using SAGA GIS 9.0.2 software and one of its tools that I'm exploring is Object Based Image Segmentation (OBIA). For my use, I'm exploring of SAGA GIS power to segment UAV imagery. The object i'm trying to identify is Seagrass species and its shoot density. I have found SAGA GIS quite useful the hurdle i'm trying to overcome is an indepth explantion of the parameters that I need to input in SAGA software for doing OBIA analysis. The only tutorials that I have found are limited explanation and the software version is 7.0 below. So the only parameters that are used in the old tutorials are which neighborhood is used and option to do post-processing (unsupervised classification).

I have found a specific forum which linked a paper on indepth explanation but with my limited knowledge, its explanation on the parameters isn't explained fully. After combing to many pages and forums in sourceforger, google scholar, youtube and such other places, there isn't a specific text that explains in depth for example what effect if my value Feature in Position Space is bigger. Does the space between each segmented area increase or decrease? and many such more questions.

I'm currently still experimenting but this research is for my undergradute thesis so it will be a great help if there is an in-depth explanation of each parameter and the effects its has with different values inputed. To my understanding, for my version the explanation is also very minimal for each parameter in which is include in the SAGA application.

Any help is much appreciated!
