I would like to know if opencv can capture text as small as a few pixels

how to size picture opencv work ?


your question is unclear. you will need to elaborate. please post source code and pictures, if you have that.

What is the smallest image size that can be captured by opencv?

1x1 or 0x0 if you want to be mathematical about it.

why don’t you just tell us what you want to capture, and how you want to capture?
