Hi All, I implemented Robert's Edge Detection algorithm ( http://homepages.inf.ed.ac.uk/rbf/HIPR2/roberts.htm). I have made an issue on GitHub( https://github.com/scikit-image/scikit-image/issues/513) and I have the implementation with me. I also created a new topic for this in this group. Should I submit a pull request on GitHub? Regards, Umesh

_mask_filter_result function
by Umesh Sharma 20 Apr '13

hello, can anyone tell me what "_mask_filter_result" function is doing in edges.py (skimage/filer/edges.py), i am getting error when i am calling sobel edge detector in latest version of scikit-image . and why we are using it , i mean in sobel edge detection after applying the convolution , can't we directly return that new matrix. Thanks Umesh Kumar Sharma 4th year UG student CSE IIT kharagpur

Test Failure

Hi, 1 - I had send a PR on histogram backprojection. at that time travis build was successful. Then i made some modifications for PEP8, but travis build shows errors which i don't understand. https://travis-ci.org/scikit-image/scikit-image/jobs/6472929. But i haven't changed any functionality of code and it works fine in my system as good as old. 2 - Also, I didn't get the concept of writing of tests for my code. What actually the tests do and how should I write a good test code? Regards Abid K

The STAR code is in OpenCV, so this would be modifying that code for using the numpy / cython array structures. Also, to give the project sufficient scope, we'd need to implement some other features as well, e.g. binary features. Please note that it is important to have contributed some code changes to scikit-image in order to be considered for the GSoC, so please have a go at fixing some bugs or implementing a new feature as soon as possible. Thanks Stéfan

But I am not going to do that alone :) Is there a way to add plugins by simply "dumping" plugin files into place? This was part of the thinking when we designed the skimage.io plugin infrastructure (so it would be easy for, e.g., Debian to add new formats by simply unpacking into the right location). I am not entirely happy with the complexity of the io module in skimage, and would love to hear ideas about how it can be simplified, perhaps integrating with imageio. Stéfan

Thank you for the answer , although I have already found who might be the mentors from the discussion on github. :) Regards, Abid K. opencvpython.blogspot.com On Fri, Apr 19, 2013 at 4:03 PM, Stéfan van der Walt <stefan(a)sun.ac.za>wrote: > On Mon, Apr 8, 2013 at 9:31 PM, abid rahman <abidrahman2(a)gmail.com> wrote: > > Can I know who is the mentor for scikit-image GSoC projects?

I'm sorry, for some reason these messages slipped by my radar completely unnoticed. We've been communicating in the mean time, but here's your answer: GSoC project leaders: Emmanuelle Guillart Stéfan van der Walt Tony Yu and Aron Ahmadia for projects relating to a proper backend / dispatching system with integration of numba and opencl backends. I'm sure the other members of the team will also help out--these are just the people who signed up. Stéfan

Ah, at the risk of sounding even more like an idiot... on what page are the close/reopen buttons? I can't find ones on the GH pull-request page, or on the Travis-ci build. Sorry! Haven't interacted with the codebase since travis was added and clearly I've no idea what I'm doing. Definitely won't merge my own PRs anymore. Hahaha. Zach
