The image quilting algorithm is an algorithm used for texture synthesis and transfer in images, described in the SIGGRAPH 2001 paper by Efros and Freeman. In this section, we shall touch upon the main idea behind the quilting algorithms for implementing texture synthesis and transfer, and show a couple of results obtained with an implementation of the algorithm. The code is left for the reader to implement (refer to https://sandipanweb.wordpress.com/2017/10/24/some-computational-photography-image-quilting-texture-synthesis-with-dynamic-programming-and-texture-transfer-in-python/ for more information).
Texture synthesis refers to the creation of a larger texture image from a small sample. For texture synthesis, the main idea is to sample patches and lay them down in overlapping patterns, such that the overlapping regions are similar. The overlapping regions may not match exactly, which will result in noticeable artifacts around the edges. To fix this, we need...
