AlanLuSun / TPS-Warp

This repo contains both matlab and python implementation of using TPS to perform warp given a set of correspondence points.

Thin-plate-spline (TPS) warp

Warp-image-TPS （python）

• Using opencv to implement ThinPlateSpline
• If it happens the error "cv2.createThinPlateSplineShapeTransformer() not found", please install opencv-contrib-python with the command below

pip3 install opencv-contrib-python
# or use below code image for faster download if you are in China
pip3 install opencv-contrib-python -i https://pypi.tuna.tsinghua.edu.cn/simple

• There is a bug for function tps.applyTransformation() which only accepts np.float32 data type

TPS-Warp (Matlab)

• see mytest.m as an example

Example

• For convenience, we also provide an image named "1.jpg" for test TPS warping.
• An image warping example
