PANCARD AADHAAR

[Shubhranshu Panda]

I don't know how to extract particular text from a standard image type. I want to extract the name, dob and PAN number from the PAN card. I have attachhed a sample image for reference.

Use NER model after you extract the text with Oct

If you are interested in extracting both text and photo them use YOLO object detection and then tesseract

Thanks.

Additionally, is there any way I can instruct the system to look for the exact location for text extraction?

You have annotations tools where you can annotate and train

I use labellmg .There are many you can explore

NER seems like overkill for this.

Try using template matching for your use case(I am assuming that PAN card format is same all over India). Atleast dob and pan card number can be found easily using regex. For names, you can reject all the other text boxes like 'INCOME TAX DEPARTMENT', 'GOVT. OF INDIA', then you will be left with only the fathers name and holders name just check for the y coordinate among those two text boxes.

[Shubhranshu Panda]

yes. that's what I am doing right now. but there's an issue.

While I am getting all the names, I am not able to detect the [father's name] even if it is in the lot and some unwanted garbage is sometimes getting in the way.

I am attaching a sample image for your reference. and the text generated from that (in a list).

['MONIKA MAHADEV SHINDE', 'ARa Gar', 'GOVT. OF INDIA', 'MAHADEV SHINDE', '31/10/1992', 'Permanent Account Number', 'EJAPS0276M ~', 'MONIKA 1 SHIN OE :', '- 8', 'Signature']

I am obtaining the above list. and the father's name shows "ARa Gar" and not MAHADEV SHINDE.
As the unwanted text is not generated always, I need a way to figure out what the actual name might be.

Can you please look into this??

[Ameer Sheik]

Can You suggest some tools related to template matching

[Ameer Sheik]

I'm also facing the same issue..... Can someone throw some time light here please

You could use OpenCV to define a template with regions of interest (ROIs) and then use tesseract to OCR them?
