Some Variational Image Processing: Poisson Image Editing and its applications in Python

Poisson Image EditingThe goal of Poisson image editing is to perform seamless blending of an object or a texturefrom a source image (captured by a mask image) to a target image. We want to create a photomontage by pasting an image region onto a new background using Poisson image editing. This idea is from the P´erez et al’s SIGGRAPH 2003 paper Poisson Image Editing.The following figures describe the basic…See More

"@Andrew Ford actually this is part of a few assignments from the coursera course which is still running, so it will be a breach of honor code to share the code here, however, the course is free and anyone can enroll to get a few starter codes."

Some more Social Network Analysis with Python: Centrality, PageRank/HITS, Network generation models, Link Prediction

Posted on September 21, 2017 at 11:30pm 0 Comments

In this article, some more social networking concepts will be illustrated with a few problems. The problems appeared in the programming assignments in the

coursera course Applied Social Network Analysis in Python.  The descriptions of the problems are taken from the assignments. The analysis is done using NetworkX.

The following theory is going to be used to solve the assignment problems.
