Selective blur or mask

    Is there a way to selectively blur or mask something like a license plate from within KRpano? I looked at the post production tool and the controls seem only to apply this type of adjustment to the entire pano. In this case, I have too many classrooms where wifi network credentials are written on to white boards. I'm hoping to avoid having to recreate the panos so that I can blot out the credentials in PTgui or photoshop.

    Hello Reggie,


    It sounds like you have already processed the panoramas through Krpano, and now want to add blur to parts in some of them, hopefully without having to process the panoramas again.

    If keeping credentials fully private is a main concern, I would recommend editing the original panoramas and running it through Krpano again. Krpano cuts the panorama images into many tiles / pieces, and these get sent to the viewer's web browser before any post processing occurs. Adding a visual blur will hide the credentials in the viewer; However, someone could look in the web browsers logs to find the original files with the un-blurred content.

    If the credentials are only in a few panoramas, you may be able to just regenerate those, and replace it's output folders.


    If you're looking for a simple, ready to use solution for adding blurred rectangles into scenes in the virtual tour, I am not currently aware of one.

    If you'd prefer to further explore creating a post processing workflow, the solutions that come to mind would be to either use pp_blur, which would require identifying coordinates manually, defining the rectangle, and converting coordinate spaces, or to create a custom JavaScript tool that can display the overlay(s) based on given coordinates.


    I hope this information may be helpful, and good luck on your project.
