Guess why I need to force myself saving some money? Because I can't help buying random stuff.

This week is glow sticks from Japan, 2 USD per stick. It's pretty expensive in terms of being a toy (it's not a toy). But guess what, it's super cooool!

I paid 0.526USD/Hour on AWS and only get 2 FPS.

I rent a GPU on vast.ai for less than 0.5USD/Hour, and I got 12.5 FPS.

Today's lesson: Do not trust AWS.

I need an explanation...

"Boost"

I mean, the heavy lift is done by onnx and yolo, I just invoke them and copy files based on the result.

But still, it's exciting to see my code actually working. BTW I'm using kotlin/jvm. So no python nonsense.

YOLOv8 detect birds in video clips.

I think the main issue of this toot is I use the default 640x480 resolution, which makes the picture too small to distinguish the details. Running on 1080P natively does cost a lot of RAM and time, but it can tell it's a bird very quickly and confidently.

I need to go sleep...

OMG it's working!!!

ONNX runtime for java with kotlin.
Using FFmpeg to read videos.

OpenCV can give boxes when using CPU, but somehow the boxes are all zero if running on CUDA.

The ORT is much better than OpenCV. I love onnx :)

Don't know why but yolov8 gives me 0 bounding box with opencv dnn.

ok, it's really confident about that

Well... In theory, a bird can be an airplane?

?

Me, trying random stuff to make cpp work on jvm:

YOLOv4 on Kotlin with opencv!

Is this caused by solar activity? Or just my phone about to die?

I use my old phone as a monitoring camera to see if there are birds coming. It's outdoor from 9AM to 6PM, for the past 3 days.

did some biking. I think my body is gradually catching up. Today I didn't feel exhausted after finishing this ride. Cool.

Power is still not coming back, but I managed to borrow some electricity from my neighbor.

And they said they can't find an electrician to fix the problem. So I got my meter. Hope I won't kill myself

Even 4G is out... Now fallback to 2G...
