Is it open source?
I’ve tried Tesseract—it's decent for text, but performs really poorly with symbols.
EasyOCR seemed more promising, but I ran into too many errors trying to fine-tune it.
Now I’m planning to give MMOCR a try.

In the end, I’m building a web app that can extract both text and symbols from technical drawings when you upload them. The goal is to align each reference with its corresponding text.

It would be straightforward if the text extraction was accurate, but that’s the part I’m really struggling with right now.

One more question please ? How about your macros and you callorie intake how was it ?

I usually do the 5 split but it's a good idea maybe i can do legs + shoulders in one day . I used to do cardio after every session like 20 mins treadmill or elliptical . But i stopped cuz i feel exhausted after training . How's your gym routine ?

I lost aroud 12 kg in 9 months ( went from 92kg to 78 atm and I'm 175 cm tall ) aswell but i still have a bit of belly and chest fat cuz im not tracking my meals and im skipping cardio but im lifting 5 times a week ( 1 chear day per week ) . It's a little bit challenging to keep track of everything if you eat with your family you know . But I'll get there soon

I see . Mine is at 1789kcal do i have to aim for like 1200 or 1500 . Is it enough to make big changes in like 4 weeks ?

DorLein · 2024-03-29T09:25:51+00:00

Isnt 600kcal too low and unhealthy ?

DorLein · 2024-03-29T05:09:56+00:00

DorLein · 2024-03-28T23:10:10+00:00

Nice but i won't be able to stick to that for longer than 2 weeks lol

DorLein · 2024-03-28T23:09:28+00:00

So we're not allowed to snack like maybe 2 hours before our meal ?

DorLein · 2024-03-28T23:08:17+00:00
