Optmizing target detection and tracking stability
1- improve contrast
2- avoid repetition
3- check the target histograms in photoshop
4- measure scale for tracking by dividing your camera-to-target distance by ~10: 20 cm wide target would be detectable up to a distance of about 2 meters (20 cm x 10)
5- check the target in gray scale
6- avoid curved shapes

What did DeepSeek figure out about reasoning with DeepSeek-R1?
https://www.seangoedecke.com/deepseek-r1
The Chinese AI lab DeepSeek recently released their new reasoning model R1, which is supposedly (a) better than the current best reasoning models (OpenAI’s o1- series), and (b) was trained on a GPU cluster a fraction the size of any of the big western AI labs.
DeepSeek uses a reinforcement learning approach, not a fine-tuning approach. There’s no need to generate a huge body of chain-of-thought data ahead of time, and there’s no need to run an expensive answer-checking model. Instead, the model generates its own chains-of-thought as it goes.
The secret behind their success? A bold move to train their models using FP8 (8-bit floating-point precision) instead of the standard FP32 (32-bit floating-point precision).
…
By using a clever system that applies high precision only when absolutely necessary, they achieved incredible efficiency without losing accuracy.

The impressive part? These multi-token predictions are about 85–90% accurate, meaning DeepSeek R1 can deliver high-quality answers at double the speed of its competitors.Chinese AI firm DeepSeek has 50,000 NVIDIA H100 AI GPUs
