The pixel size in your before image aren't even remotely close to the ones in your after picture. You should state in your example that the final image will be larger than the original, because as it shows now, you are comparing grapes to watermelons
My mistake. I should not have put "before and after" since the image shows the left and right halves of the same image. The left side shows the left half of the original image, the right side shows the right half of the image after it has been cleaned up. So technically, there is no before and after.
It would be more accurate to say that this image show before and after:
