GSOC 2016- Making Label Detection results configurable and improving documentation- Week 12

TL;DR Last week I had worked moving the helper functions for filling Alt Text of image file to a new service; and moving the reused/supporting functions of the tests to an abstract parent class, GoogleVisionTestBase. This week I have worked on improving the documentation of the module and making the label detection results configurable.

With all major issues and features committed to the module, this week I worked on few minor issues, including the documentation and cleanup in the project..

It is an immense pleasure for me that I am getting the feedbacks from the community on the Google Vision API module. An issue Improve documentation for helper functions was created to develop more on documentation and provide the minute details on the code. I have worked on it, and added more documentation to the helper functions so that they can be understood better.

In addition, a need was felt to let the number of results obtained from the Vision API for each of the feature as configurable, and allow the end user to take the control on that. The corresponding issue is Make max results for Label Detection configurable. In my humble opinion, most of the feature implementations and requests to the Google Cloud Vision API have nothing to do with allowing the end user to configure the number of results. For instance, the Safe Search Detection feature detects and avoids the explicit contents to be uploaded, and does not need the number of results to be configurable. However, the taxonomy tagging using Label Detection should be user dependent, and hence, I worked on the issue to make the value configurable only for Label Detection purpose. This value can be configured from the Google Vision settings page, where we set the API key. I have also developed simple web tests to verify that the value is configurable. Presently, the issue is under review.

I have also worked on standard coding fixes and pa-reviews and assisted my mentor, Naveen Valecha to develop interfaces for the services. I assisted him on access rights of the functions, and fixing the documentation issues which clashed with the present one.

Lastly, I worked on improving the README and the module page to include all the new information and instructions implemented during the Google Summer of Code phase.

With all these works done, and all the minor issues resolved, I believe that the module is ready for usage with all the features and end user cases implemented.

Next Week, I’ll work on creating a video demonstration on how to use Google Vision API to fill the Alt Text attribute of an image file, detect the emotion in the user profile pictures and to group the similar images which share the same dominant color.
