cxcxcxcx / imgwarp-opencv Goto Github PK

It's excellent, I use it as a warp tool. To use it as a liquification, I. E. to only move the hit point based on a radius. I can fill the surrounding area of the item I want to move with control points all right. Is there a simpler way?

I am using Microsoft Visual Studio 2017 on Windows 10, and OpenCV is installed properly and I can run some simple programs of OpenCV which can be found around the internet.

How can I run this project as a person who is not familiar enough with OpenCV on c++? I know some basic c++ already, but never been involved with a project at this scale, so please explain it step by step, and as a suggestion, better to add the explanations on how to run the code, on the README.md file.

Hello.

First for all, thanks for sharing great code.

I have found some memory crashing case.

When i put the same zero control point , some code makes crashing.

// 2 zero points
qsrc.push_back(cv::Point_<int>(0, 0));
qsrc.push_back(cv::Point_<int>(0, 0));

// 2 zero points
qdst.push_back(cv::Point_<int>(0, 0));
qdst.push_back(cv::Point_<int>(0, 0));

In imgwarp_mls_rigid.cpp

tmpP *= w[k] / miu_r;

Above code makes dividing by zero without handling.

Any idea why this is not responding to clicks/drags/etc?

@cxcxcxcx ，thanks for your project。
when i compile the code. It comes the error as follows:

It seems several files are not exist such as ui_deformwin.h .
can u help me?

Is there an example without an interface?
I work in an animation render similar but not so good

https://4232.cf/quinema-your-animation-assistant/

double *w = new double[nPoint];

rDx.create(tarH, tarW);
rDy.create(tarH, tarW);

if (nPoint < 2) {
    rDx.setTo(0);
    rDy.setTo(0);
    return;  // do not release the memory of w

}

thanks for your code. u really did a great job. did your code include the Rigid Lines?

Exception in opening a file

This is the performance of the demo.

And this is my result. I wonder why this happen. I use the rigid transformation.

I have installed opencv3.1.0 in mu ubuntu 16.04.
I can import cv2 normally in python.
However, when I tried to compile these files using cmake

mkdir build
cd build
cmake ../src/
make

the precedure cmake is correct.
But make occures error, that cannot find cv.h in src/delaunay.h file.
Please help me .
I want to use these image warping method as my image preprocessing procedure. And I don't know how to import it into my python program.
