Our code for the paper "Single-Perspective Warps in Natural Image Stitching"

Single-Perspective Warps in Natural Image Stitching

This repository is our implementation of the IEEE TIP 2019 paper, Single-Perspective Warps in Natural Image Stitching. If you use any code or data from our work, please cite our paper.

The codes are designed for two-image stitching, for multiple images, please refer to Single-perspective-warps-multiple.

Usage

1. Download code, add images in the folder "Imgs" in the main path and run the "main.m".

2. This code has been tested on 64bit Windows; for other platforms, you'll need to compile your own mex files in folder "LSD_matlab" and "texture_mapping";

single-perspective-warps's Issues

Stitching result has something wrong make it looks so bad.

I tried to run the project with matlab R2022b in Windows 10 x64.
i changed the line 9 of "addNeedPaths.m" to locate my VLFeat lib, and line 95 of "main.m" to
"optimized_V = reshape(V_star, [], 2); clear V_star;"

because vec2mat() is not recommended by matlab, so i change it to reshape according to the document
(https://ww2.mathworks.cn/help/comm/ref/vec2mat.html#d126e86110)

then the program execution result was so weird, and i don't know what's wrong.

step

hello ,respect teacher.
can you give some additional step?
according this step i can not to achieve this goal.
thank you
