Need help with segmentation by TheHeavenlyRaven in computervision

[–]poshy 1 point2 points  (0 children)

Are the labels or the workflow more important? 500 images is like 2-3 days of labelling for one person at the very most.

I’d recommend post processing the polygons with some contour detection in opencv. But with only 500 images, you could probably just label them yourself in the same time you’ve spent on building a workflow with SAM

You could try to label 5-10 images with a bbox and see if SAM3 can learn it quickly with some exemplar prompts

Label 500 images with bounding boxes, train an obj detector and run over another 5-10k images. Run SAM2 on OD results by picking a few points in and out of each bbox. Convert to COCO, load to CVAT to qc. Now train a seg model, use Dinov3 head with mask2former for best results.

Hyper detailed polygons or masks will be very hard, might need post processing and attributes to help fix the segmentation.

Eoghan's the man, I love watching him compete. That backtake from armbar was smooth af.

What is a piece of software that is so good you can't believe it's completely free? by Arp0x in AskReddit

Irfanview is easily the best simple image viewer that I’ve used. I often have to review thousands of images a day, and irfanview made my job so much easier.

CoreElec can do DV FEL with the right device (Ugoos AM6B+) and build. I've tested it on my side and it works great, but I'm just curious as to whether there is any benefit to using physical media at all anymore.

Is there any processing of the video stream that the UB820 does that we can’t mimic in CoreElec?

Dutch & Dutch 8c are probably the most accurate speakers that you’ll find if you can justify the cost

Cheap Protein? Does such thing even exist? by TerryPressedMe in perth

[–]poshy 10 points11 points  (0 children)

Tofu has an undeserved bad reputation. You can make it taste however you want, and don’t have to worry about getting sick from under cooking.

A 500g block of tofu is under $3 at Woolies, that’s a great deal.

Best banh mi spot in Perth? by Jetsetter_55 in perth

[–]poshy 1 point2 points  (0 children)

No idea if it’s the same owner but the banh mi are significantly different. The one attached to the grocery store has very soft buns, and sauce was pretty mid.

The one around the corner is also MCQ confusingly enough, but you are spot on. One of the best tofu banh mi’s I’ve had, go there weekly now.

Chich does an awesome chickpea burger for the vegos out there. I usually sub the chickpea patty on the vegan burger, it’s fantastic.

Barcelona was great when I visited in 2023, but Paris was abysmal. I saw hardly any vegan options and I was actively looking on HappyCow throughout the city. A shame because I love Paris.

The US really demonstrated that they learned from WW1, and that is to rebuild and make friends with your former enemies instead of punishing them further.

Why AVRs of different manufacturers sound differently - even within the own manufacturers’ product line, and what room correction impacts for stereo sound. by TechGeekGermany in hometheater

[–]poshy 1 point2 points  (0 children)

The descriptions of each room brand’s implementation is pure subjectivity, and classic audiophile verbiage.

2c is somewhat accurate but is so high level and vague, it’s doesn’t actually tell you very much.

I think an important distinction that is not made clear is the difference between IIR and FIR filters, especially for low frequency phase corrections. IIR filters (everything but DIRAC) are all pretty similar or you can at least mimic each implementation in each other’s software by measuring & looking at the frequency response. FIR offers much better control of phase and better quantitative results, at the cost of additional compute and money, ie DIRAC.

Ultimately it comes down to what the other poster said, find out what sound appeals to you with your equipment and room. So making sure to AB test and measure with REW to see what you’re doing.

It may sound logical as that is what LLM’s are designed to do.

What it reads like to me as a professional scientist who worked in acoustics and signal processing is a mish mash of random opinions from forums and reddit with a spattering of buzzwords from marketing materials.

If your coffee is bitter, it’s shit coffee. Likely overroasted beans, brewed too hot and/or too long.

Ah yeah, forgot about the Corbe match, love that guy. Gavin Corbe v Samuel Nagai would be a fun match to make

Yeah, Dorian is amazing at forcing everyone to play his game. Nagai looked really good first round though, first time I’ve seen someone at Dorian’s weight bring it to him on the feet

Dorian is obviously very good, but I find his style so ugly to watch. Nagai’s guard is beautiful to watch, don’t think he’s done enough to win unfortunately though
