[GRASS-dev] FW: FW: OSGeo-SoC 2016 application

[Yang, Bo (yangb2)]

Dear Moritz,

Thank you for the reply, and thanks you and Markus could be the mentor of the i.segment project! There are only two days left for submitting the proposal, take into consideration I think I need to switch to the topic of i.segment project now. For my cokriging fusion topic I think I could do it after this summer in the future work. 
I've read the source code and Eric's wiki of GSoC 2012 [0]. I think I will prepare the proposal following the direction of adding new algorithms to segment an image into objects-- more than region-growing algorithm. Moritz, you mentioned segmentation algorithm: mean-shift, split-window and watershed. I think some unsupervised classification algorithms would also be possible such as: dynamic thresholding and markov random field (MRF). If you think it is OK, I will start the preparing the draft of proposal from now on, and I think I could have the first version send back to you by tomorrow (Thursday). If you have any suggestions and comments please let me know.
Thanks again to both you and Luca for your guidance and patient. 

Best wishes,
Bo Yang

As mentioned privately, I'm only available, like you, as co-mentor for testing and applied advice, not so much on the coding side.

In light of the absence of mentors, you might want to reconsider the choice of topics. For i.segment, Markus Metz is willing to deal with the C-side and I mentor for the rest.
