Rectangling Panoramic Images via Warping

Rectangling Panoramic Images via Warping的论文复现 C++实现

因为南开某实验室的考核做的...

(improved) seam carving的实现结果有点问题,有时会产生重复插入引起最终插值结果在Opengl纹理贴图上的扭曲,至今无法解决。
经排查大致认为扭曲撕裂等现象的原因是上述导致的

原论文所说

If we represent the two end points of a line segment as a bilinear interpolation of its quad vertexes Vq, we can write e as a linear function of Vq.

我的实现是逆双线性插值,我也不知道原论文是不是...

In this case E is a quadratic function on V and can be optimized via solving a linear system.

此处我的实现是转成最小二乘估计的形式用最小二乘求解,不知道原论文是否是这个意思

参考

在此基础上改了很多东西..
