Segementation fault #2

Open Rnandani opened 7 years ago

Rnandani commented 7 years ago

I am trying to implement code for soft matting. For the implementation, i am using original image and its sparse map(edge map) as shown- image sparse_map I am getting segmentation fault. What could be the possible reason? For Matting, r u using scribble based image or trimap?

Hi Rnandani,

I'm afraid I've got no idea what might be causing your segfault. This implementation is scribble based. It's also leftover from an old college project, so I wouldn't recommend using the code directly if you care about speed and stability!

Hi Rnandani, I know it is a little bit too late but I think I have the answer. I had the same segfault error and after debugging for a while, I figured out that problem was caused by the function to load an image : SDL_LoadBMP which can only load BMP. To be more general, I changed it with IMG_Load; you have to install SDL_image and import it (#include "SDL/SDL_image.h")
