The SeamCarving results are not the same when recomputing the input image

Hello.

Thanks for the sharing, and the quality of the code is good!
However, I find some issues in the local warping using seamcarving that cause the different results even when computing the same input image.

In the Line 175 in addSeam.cpp, the code uses rand() to generate different colors for seams. However, when computing the next seam, the colored image would be used to compute the energy. The energy would not keep the same in different experiement repeatition since the colored seam would involved in energy computation and it is given as random. As a result, the final seams obtained would not be the same, and are slightly dependent on the randomized color seams.

           #if 1 
        
           	color[0] = rand()%256; 
        
           	color[1] = rand()%256; 
        
           	color[2] = rand()%256; 
        
           	// Draw red on the seam 
        
           	for (int i = 0; i < h; ++i) {		 
        
           		img[optVertSeam[i]*3] = color[0]; 
        
           		img[optVertSeam[i]*3+1] = color[1]; 
        
           		img[optVertSeam[i]*3+2] = color[2]; 
        
           	} 
        
           #endif 
        
           #if 0 
        
           	// Draw red on the seam 
        
           	for (int i = 0; i < h; ++i) {		 
        
           		img[optVertSeam[i]*3] = 255; 
        
           		img[optVertSeam[i]*3+1] = 0; 
        
           		img[optVertSeam[i]*3+2] = 0; 
        
           	} 
        
           #endif

The overall image is updated with the output image with a color seam from addSeam.cpp. And in the next loop, the input image is resulted fromthe overall image with color seam.

The saved final result picture is distorted

Hello，when i try to save the final image in the meshwarp.m after line 42 use the code 'imwrite(outputimg./outputimgcount,'res.jpg');', and i find that the saved iamge is too small compared to the original image. I'm not sure is the problem of saving ways or somthing else. Could you give me some advice? Thank you very much.

Issue with MEX

Hey, I wanted to use this code for my project implementation but I am having problems with Visual C++ 2013 and MATLAB R2017a. Could you specify the Matlab version and the compiler you used for the work?
