# Image Mosaic based on SIFT and RANSAC **This is the project design of course *Digital Image Processing* (2017-2018, Fall) in Tsinghua University presented by Dr.Shengjin Wang**. ## Requirement 1. OpenCV 3.4.1 for python 2. OpenCV-Contrib 3.4.1 3. numpy 1.8.0rc1 or higher ## Intro ### SIFT SIFT(Scale-invariant Feature Transform) is a computer vision algorithm presented by Dr.David Lowe in 1999. It can extract feature points of a image, and has been proved very efficient in Image Mosaic. ### RANSAC RANSAC can be used to fit linear relation. Different from The Least Square Method, RANSAC is especially efficient for strong noisy data. See [Report.pdf](https://github.com/raxxerwan/SIFT_RANSAC/blob/master/Report.pdf) for more detail. ## Images Set Put all the images you want to mosaic in `./Pics/`. The image files should be named in ascending order. The algorithm will mosaic them from left to right according to the index of file names. For example: ``` ROOT/ └----Pics/ |----table1.JPG |----table2.JPG |----table3.JPG |----table4.JPG └----table5.JPG ``` ## Get Started! Run: ``` python SIFT_Project.py ``` or: ``` python SIFT_Project.py --img_dir=YOUR_IMG_DIR --result_dir=YOUR_DIR --result_name=YOUR_NAME --format=YOUR_FORMAT ``` where: ``` --img_dir: The path of your images set. Default:'./Pics/' --result_dir: Where the mosaic result should be saved. Default:'./Result/' --result_name: The file name of the mosaic result. Default:'result.jpg' --format: The file format of your images set. It can contain various format. Default:'jpg png' ``` The result image will be placed where you specify or in `./Result/` by default. ## Samples ### Before: <img src="https://raw.githubusercontent.com/raxxerwan/SIFT_RANSAC/master/Pics/table1.JPG" width="50%" height="50%" /> <img src="https://raw.githubusercontent.com/raxxerwan/SIFT_RANSAC/master/Pics/table2.JPG" width="50%" height="50%" /> <img src="https://raw.githubusercontent.com/raxxerwan/SIFT_RANSAC/master/Pics/table3.JPG" width="50%" height="50%" /> <img src="https://raw.githubusercontent.com/raxxerwan/SIFT_RANSAC/master/Pics/table4.JPG" width="50%" height="50%" /> <img src="https://raw.githubusercontent.com/raxxerwan/SIFT_RANSAC/master/Pics/table5.JPG" width="50%" height="50%" /> ### After:
