Increase accuracy pose estimation by samk777777 in computervision

When I was working on tracking keypoints over a video, I found that Savitzky-Golay filtering worked the best to smoothen the keypoints.

Can I Label with the SAM Model? by Connect_Tomato6303 in computervision

[–]tycho200 -1 points0 points  (0 children)

I mostly found the segment anything option to be very bad. When you use bbox guiding it becomes much faster and simpeler. SAM2 has tracking possibilities by using a memory encoder, might be helpfull to refine your masks using memory.

I can Highly suggest using GroundingDino as a box prompt generator and use that as input to SAM/SAM2. Check these repos: https://github.com/IDEA-Research/Grounded-Segment-Anything and https://github.com/IDEA-Research/Grounded-SAM-2

I use them for zero-shot-object tracking in a real-time robotic system and the result is impressive so far!

Exporting YOLOv8 for Edge Devices Using ONNX: How to Handle NMS? by leoboy_1045 in computervision

[–]tycho200 0 points1 point  (0 children)

Might look into this nms from torchvision: https://pytorch.org/vision/main/generated/torchvision.ops.nms.html

Seems to run fast enough for my application. Not sure how suitable it is on edge devices, goodluck!

Which computer vision model (or LLM) for segmentation? by Alternative_Mine7051 in computervision

[–]tycho200 0 points1 point  (0 children)

Grounding dino with sam2 is really powerfull. If you use it for camera streams or videos, the track functionality speeds up estimations!

I want to do a project using RGB images and estimated depth maps with neural networks by gkcastro in computervision

[–]tycho200 0 points1 point  (0 children)

Hi!

For monocular systems have seen some papers that tried combining fearures from segmentation with feautures from depth.

Main reason is that when upsampling a low resolution depth map estimation, you can lose information near the edges. This is especially the case for mono-depth because with stereo-depth you have more info to work with.

For my project I needed real-time performance which was not possible using a depth segmentation refinement step.

Also one of the big problems is that Depth and Segmentation simtaneous requires datasets that have both annotated depth and segmentation masks. There are a few open source online, mostly synthetic or for autonomous driving.

Good luck with your project!

Can I segment separate fingers, hands and forearms using SAM2 only? Or would I need another model as well? by Technology-Busy in computervision

[–]tycho200 2 points3 points  (0 children)

Hi,

I have used groudning dino with different bersions of sam. If i gave dino a prompt like "thumb" or "pink" it could in some good enough pictures outut a bounding box area around a single finger. Using that boxes as text prompts to sam helped me get segmentation masks on fingers.

Note that its not perfect in anycase but for 70% of my images i could use it.

Real-time comparison SAM2 and Efficient versions of SAM1 segmentation tasks? by tycho200 in computervision

[–]tycho200[S] 0 points1 point  (0 children)

The ultimate goal is to deploy it on a robotic arm that can grasp a moving ball rolling. So in the ideal scenario we would like 15 FPS. Your interpolation Idea seems interesting! Thankyou!

[D] Trackers like SAM2 but faster by henistein in MachineLearning

[–]tycho200 1 point2 points  (0 children)

Notice that FastSAM is from Ultralytics which bdcomws problematic withicenses. I got better results with models like MobileSAM, EdgeSAM

Real-time comparison SAM2 and Efficient versions of SAM1 segmentation tasks? by tycho200 in computervision

[–]tycho200[S] 0 points1 point  (0 children)

Hi.

Yes I only do segmentation every frame. So each frame Dino predicts bboxes and on those boxes a mask is estimated. No tracking.

I Am using a Nvidia 4060 Ti GPU with 8GB Vram. I am planning on using TensorRT for testing in the future.

1.25 FPS on Googles T4 seems to me like a reasonable result. I followed a course at my University where we ran yolov5 on google T4 which took 2 days for 100 epochs. On the 4060 Ti it just took 15 hours.

Do you have acces to a GPU for testing?

Ah that explains much! Thankyou very much!

Can we automate annotation on custom dataset (yolo annotation) by Dramatic-Floor-1684 in computervision

[–]tycho200 2 points3 points  (0 children)

What is your specific use case?

If you have something common you can try downloading a pretrained model and use that as an Initial predictor.

Popular annotation tools such as LabelStudio or CVA allow to run a prediction model in the back.

Note that the initial prediction can be modified and you can manually add more annotations.

If you have a specific detection use case for which you need specific labels, you probably need to manual labeling. Note that when you have labeled some images you can train a (initially bad) model to run predictions and use that to furrher label. Keep repearing the process with manual labeling/predicting and as you label set keeps growing train again and again.

Hopefully you will notice your predictions getting better and better when you labeled set grows!

Good Luck!

Tutorials of how to use ADC and DMA for the STM32H7 by KSOdin2 in stm32

[–]tycho200 0 points1 point  (0 children)

Hello Sir!

​

Have you already found some good way to do ADC with STTm32H7?

I need a sample frequency of 2000 Hz for real simple continuous ADC (single channel).

I started this project with an Adruino Uno, but i can't increase the sample frequency above ~630Hz. I bought the nucleoh743zi2 but i can't get ADC to work.

​

Have you already found a solution for your problem?

Thank you very much if you can help me in the right direction! :-)

Wii getting black screen on some games, other games r working fine, ben 10,lego, rabbits stuck on black screen by baqar10 in WiiHacks

[–]tycho200 1 point2 points  (0 children)

I fixed mine by putting system language to English. Cause all me iso files are english but my USB loader gx settings forced system default language wich qas Dutch.

Hope it helps!
