Remove illumination noise from image to detect april tag

275 Views Asked by At

enter image description here

In this image,I am trying to detect apriltag, for which I am using lib-dt-apriltags library. As per my knowledge,detection of apriltag is possible when we have clear edges.But because of the illumination / glare / reflection due to light,I am unable to detect it.And I cannot implement heavy computation in my processor.

Is there a way to remove this noise ? What this problem is referred as so that I can search for document?If you have any sites/related document/links in mind,please do share.

I am about to implement this solution in continuous live feed and camera will be in motion while apriltag comes in frame so it has to be fast.(Also,Lens of the camera was clean when this problem of reflection occured.)
