Yea, I was assuming what was happening was that the derivatives were being computed for the whole image even though they were only needed in the masked region. Should I report this as a bug somewhere? |

| 2015-06-27 06:32:28 -0600 | asked a question | seamlessClone runtime proportional to image size? I have been playing with the new seamlessClone function in OpenCV3. Of course the runtime is proportional to the size of the hole that is selected. However, I've found that with a fixed hole size, when the size of the image increases, the runtime increases substantially. For example, if I fill a 200x200 hole in a 500x500 image, it takes < 1 second. Then if I fill a 200x200 hole in a 3000x3000 image, it takes 20 seconds. (The 500x500 was a cropped version of the 3000x3000 so that the hole and source could be identical for testing to make sure it wasn't a function of the data in the hole, etc.). Can anyone confirm this behavior? Thanks, David |
