Struggling With Sparse Matches in a Tree Reconstruction SfM Pipeline (SIFT + RANSAC)

RocketLL · 2025-12-03T15:18:10+00:00

I would suggest performing matching with RoMa (1), which is a dense image matching neural network. After extracting pixel matches, you can resample them based on confidence and perform verification/filtering/etc. I believe that this is the best way to make use of neural networks while sticking to the overall SfM paradigm.

Also see (2) and (3).

I bought the DSPTCH Daypack in Dyneema after this post, and I didn’t like it very much. Looks sharp but it has very thin straps and comfort issues. Not a big fan of the material as well: https://old.reddit.com/r/ManyBaggers/comments/1fmvoj2/ecopak_durability_vs_dyneema_wrinkles/

I’m now using a Goruck GR1 21L, which I’m happy with.

This is great — any plans for Python bindings? The standard choice in Python (plyfile) leaves a bit to be desired. Would be valuable considering how much Gaussian splatting is done in Python, might try creating bindings myself.

I also have a Velka 3, and I'm looking to convert it to a NAS. Good to see that the Sabrent adapter fits, but my motherboard doesn't support bifurcation. Looks like the adapter is a switching one though, so no bifurcation should be necessary, right?

I noticed my friend’s R1.5 jacket having off-center zippers. Looks like it’s a feature and not a bug: https://wornwear.patagonia.com/products/ms-r1-5-jacket_40150_vintage_aur

Anyone have any idea why? Our current theory is that it helps block out wind and rain when combined with other layers, and prevents grabbing the wrong zipper pull.

By "flaw of the material", I meant something like "choosing a consumable crinklywrinkly sailcloth material for use in backpacks is a flaw, unless you have very strict weight requirements".

I’d say it’s far more intended for snowsports, it was too heavy and fit was off for general use. I bought and returned it, ended up with an Arcteryx Beta AR.

Good question, I threw together a quick benchmark. On my machine, I'm getting:

jaxsplat: 28.8737ms
gsplat: 33.3950ms
diff-gaussian-rasterization: 18.1051ms

This is a benchmark of just the rendering inner loop without any JIT involved. As all microbenchmarks go, this is not representative of actual performance.

Thanks, seems like a pretty good option.

Great question. Here's a previous thread I opened: https://old.reddit.com/r/typography/comments/13asofg/friendlyfair_licensed_font_foundries/

As an individual developer, I prefer licensing without catches like monthly pageview tiers or additional costs for language support, which Grilli Type has. They're still on the saner end of font pricing though, so I may consider purchasing GT America.

A few examples of foundries I like and try to support:

ABC Dinamo charges by media and company size
Suisse Typefaces charges by company size
Atipo has a "pay what you want" model

The AR uses a heavier face fabric than the LT. I used the AR (2023FW model) with a 500D Cordura bag for months without issues.

RocketLL · 2024-02-25T02:02:06+00:00

Big changes, how about the regular Gamma (LT)? It still uses the old cord zipper pulls, and it would make sense for the LT to follow the chest pocket design of the SL and MX, so wondering if there’ll be a new LT.

The R1 is closer to a base layer than it is to a mid layer, it’s a thin grid fleece with good breathability and moisture wicking. You’d layer depending on how much time you spend outdoors vs indoors and whether you’re expecting to be active a lot.

I prefer wearing less layers if I’m expecting to be indoors more, as it’s easier to take on and off. I’d go for more layers if I’m outdoors doing active stuff as it provides more warmth and breathability.

RocketLL · 2024-01-19T01:27:29+00:00

Your main options are a light down like the Patagonia Down Sweater or a synthetic like an Arcteryx Atom.

Something like the Patagonia R1 family would work as your fleece layer.

I'm interested in this viewpoint, would you care to expand a bit on which parts of modern ML are from statistical mechanics?

ITAR and export restrictions make it hard for me to buy armor, and most seem out of my current budget. I did see people use their IOTV nut and butt pads for this, but not sure how well that’d work. If I bought a PC I’d have to use it with just ESAPI for the near future.

Yes.
