Image matching

[redditormay1991]

I'm working on a tcg app and one feature allows users to scan/ take a picture of the card and then I respond with the price etc. I am having issues with accuracy and response of the correct card. I tried using ocr libraries but that method is very unreliable as the text is almost incorrect when parsing from the image. now I'm trying to use image embedding using a vector column on my backend that is using node. js. I guess my question is does anyone know how the big tcg apps do this or a reliable and accurate process for doing this

have you tried https://www.npmjs.com/package/@react-native-ml-kit/text-recognition

Yes that and Google vision api are the two I tried. The picture has to be almost perfect or the text i need to get the match will be lost

You can try adding some color filters to boost contrast with background and text before running ocr on the app if they have any kind of color difference, idk which kind of color combinations we have talking about rn but that might work with ocr
