Python

Image Mosaic Based on Local Feature and RANSAC

This project is an implementation of image mosaic based on local feature descriptors and RANSAC, coded in Python language.

Image mosaic is to make a panorama from given images.

Project Structure

Runnable Python source file is ImageMosaic.py, implemented with SIFT/SURF/ORB and RANSAC algorithm. JUST CLONE THE REPOSITORY AND RUN IT!
Images to be stitched are in dataset directory, which contains 2 types, one is translation, another is rotate-scale.
The output directory contains panorama results generated by ImageMosaic.py. Images in the unblend directory are the mosaic results without seam elimination.
