How to blackstamp my head in street-level images?

I just purchased an Insta360 X4 to create street-level images for Mapillary & Panoramax and took my first pictures with it. As much as I love my hair, I don't really want to see it in street pictures.

In other users' images, I often see a black circle or something similar where a head would normally be. Unfortunately, I couldn't find anything quickly: Which image editing tool that can edit 360-degree images can I use to put a black stamp on my head before uploading the images?

Light-Sheet Image Analysis Workshop 2026

The Light-Sheet Image Analysis Workshop is a five-day intensive course that will take place in Santiago, Chile, from January 5–9, 2026, designed for students and researchers who wish to gain foundational skills in the processing and analysis of light-sheet microscopy imaging data.

The application deadline has been extended until August 8, 2025! The workshop is free to attend and travel fellowships are available. Learn more and apply here:

How that I have your attention I would like to exploit it for some work stuff. #RemoteSensing #ImageProcessing communities, I have a real quest. We're segmenting shallow underwarter structures in these archival aerial photos (grayscale, single-band) and the segmentation algorithm picks up... the waves on the water surface, not reefs and such. This gives an artefactual vergence (direction) that is not present in the layer we are interested in, i.e. sea floor. This is SVM in eCognition. Don't mention segmentation in ArcGIS (unless you're a powerful wizard, in that case I bow).
We also have a custom ML model but it's not that good either (yet?). How to get rid of them waves?! #geoscience #EarthObservation

I'm not sure if this process has a name : iteratively sharpen, then blur an image. Sounds counter-intuitive, but it gives you these results. (I guess it's Gray-Scott-esque??)
- may need to balance the 2 steps - here i used 2x Pillow's "ImageFilter.SHARPEN" + 1x "ImageFilter.GaussianBlur(radius=1)"
You can add noise each step (I didn't here).
- I used Python but you can set up actions in PS or Gimp
- need many iterations - these were 400.

Anyone know a proper name for this?

Did you know that in #vvvv you can use #OpenCV without coding? A new version of the library was just released and you can read all about it here:

From Curtis Rueden @ctrue , lead Fiji developer:

"Fiji’s migration to Java 21 took a huge step forward today: you can now download Fiji-Latest from https://fiji.sc that bundles Java 21."

For users, please download and test, and let us know what doesn't work – there's been a lot of testing already plus the compile-time guarantees of Java, but alas, nothing beats using it.

For developers, please test your plugins and libraries.

Is there a standard algorithm to create a halftone screen from a greyscale image? How was this even done before computers?
I mean like in this image. At 50%, the raster is like a checker board, and at darker tones, it's like white circles on black.
So just drawing black circles won't get you there.
