GSOC 2016- Display all the contents sharing same Dominant Colors in their images as of the current content- Week 5

Parent Feed: 
TL;DR The safe search constraint feature is now committed to the module along with proper web tests. So, this week I started off with a new feature offered by the Google Cloud Vision API- “Image Properties Detection”. It detects various properties and attributes of an image, namely, the RGB components, pixel fraction and score. I have worked on to detect the dominant component in the image present in any content, and display all the contents sharing similar dominant color. It is pretty much like what we see on the e-commerce sites.


Previous week I had worked on writing web tests for the safe search constraint validation on the image fields. This feature is now committed in the module Google Vision API.


This week I have worked on implementing another feature provided by the Google Cloud Vision API, namely, Image Properties Detection. This feature detects the color components of red, green and blue colors in the images along with their pixel fractions and scores.
I have used this feature to determine the dominant color component (i.e. red, blue or green) in the image, and to display all those contents which have the same dominant color in their images.


I have developed the code which creates a new route- /node/{nid}/relatedcontent to display the related contents in the form of a list. This concept makes use of Controllers and Routing System of Drupal 8. The Controller class is extended to render the output of our page in the format we require. The contents are displayed in the form of list with the links to their respective nodes, and are named by their titles.


In addition to the grouping of similar contents, the colors are also stored in the form of taxonomy terms under a taxonomy vocabulary programmatically generated under the name Dominant Colors.


This issue is still under progress, and requires little modification. I need to add the link to the new route in each of the nodes, so as to  get a better interface to access those contents. Henceforth, I will put this patch for review.

A very simple example of creating routes and controllers in your module can be found here.
