Hi Everyone

I have made a basic draft of my proposal here <https://docs.google.com/document/d/1-dRqhFzyWnoDJl82KsYECo00B82osR6hujaZ008N...> . Please review it and suggest modifications.

Hi Aman, This may not be 100% true for all the functionality, but I believe that the gist of the ndimage module is in the 4-5 object-like constructs in ni_support, namely: - NI_Iterator in its three flavors: point, subspace and line iterator, - NI_LineBuffer and - NI_FilterIterator. Closely linked to this is the choice of a method to deal with multiple dtypes, a question for which I don't think there is an obvious answer. Since performance is critical, you may want to take a look at bottleneck's use of templates that are pre-processed before cythonizing and compiling. If you get these right, then rather than the leaves of the tree, you will have built a solid foundation, more like the the trunk: porting all the other modules is then going to mostly be little more than an exercise in translation. So I would suggest that you devote more time to getting these fundamental questions right, as some trial and error is going to be inevitable. Jaime -- (\__/) ( O.o) ( > <) Este es Conejo.

Thank you everyone for your insightful comments. I have tried to incorporate your suggestion in the proposal. Kindly have a look at the new proposal here <https://docs.google.com/document/d/11RTVaDQDu38mrEv3WPdguxprJ-ha5kGnx2LhpEUF...> and suggest the improvements.

Hi Aman, this looks quite good to me. For the timeline I think it will take longer to get the iterators right and shorter to port the last functions at the end - once you get the hang of it you'll be able to do the last ones quickly I expect. Cheers, Ralf

Thanks once again. Regards,

Aman Singh

Hi developers

My name is Aman Singh and I am currently a second year undergraduate student of Computer Science department at Indian Institute of Technology, Jodhpur. I want to participate in GSoC'15 and the project I am aiming for is *porting scipy.ndimage to cython*. I have been following scipy for the last few months and have also made some contributions. I came across this project on their GSoC'15 ideas' page and found it interesting. I have done some research in the last week on my part. I am going through Cython documentation, scipy lecture on github and Richard's work of GSoC' 14 in which he ported cluster package to cython. While going through the module scipy.ndimage I also found that Thouis Jones had already ported a function ndimage.label() to cython. I can use that as a reference for the rest of the project.

Please tell me whether I am on right track or not. If you can suggest me some resources which will be helpful to me in understanding the project, I would be highly obliged. Also, I would like to know that how much part of ndimage is to be ported under this project since it is a big module. Kindly provide me some suggestions and guide me through this.

Regards,

Aman Singh
