Chinese carrier Fujian back at the Yuchi base today after training in the Bohai sea.
USS Theodore Roosevelt in the usual carrier spot west of Baja Mexico after leaving San Diego yesterday. The convex hull masking method does a decent job of outlining the ship but the edges are just never going to feel very natural. Might try something else next time (watershed thresholding?)
Further visualization experiments with custom region-of-interest masks for each ship. Dilating the mask makes the ROI boundaries look more natural with the 10m resolution of the satellite images. Next will see about the background compositing... [Image is the USS Ford at Norfolk on the 16th]
Amphibious carrier USS Kearsarge training with another amphibious ship off the North Carolina coast. Was hoping to also catch and annotate the large international contingent in Norfolk for the event this weekend but the clouds wouldn't cooperate.
Boundaries also looking a little less harsh if I dilate with a disk instead of a square neighborhood definition. Here with the radar images of the Prince of Wales on the 15th that sent me down this rabbit hole.

I couldn't set down trying to isolate the ship from the background in these radar images, but I realized I had already developed a workflow to get ship vector graphics to the correct image-coordinate scale for the overlays so I put two and two together....

Alternative composition of HMS Prince of Wales in this morning's radar images. The convex hull mask actually worked really well except for the concavity by the ski-jump. Needed to hang this one up though so I cheated and hand-curated the mask a bit😛. Will experiment more in a future image...

HMS Prince of Wales off the coast near RAF Lossiemouth. Great detail on this one and I did successfully experiment with using a convex hull to outline the ship for background separation. But having trouble figuring out how to transition the gradients neatly so went with my old SAR mapping for now.
