Some Computational Photography: Image Quilting (Texture Synthesis) with Dynamic Programming and Texture Transfer in Python

The following problems appeared as a programming assignment in the Computation Photography course (CS445) at UIUC. The description of the problem is taken from the assignment itself. In this assignment, a python implementation of the problems will be described instead of matlab, as expected in the course.

 

The Problems

  • The goal of this assignment is to implement the image quilting algorithm for

    texture synthesis and transfer,…

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

Poisson Image Editing

The 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 …
