Wrong edge detection in case of no background available #15

Open viveksatasiya opened 2 years ago

viveksatasiya commented 2 years ago

Hello, First of all, I want to say thank you for this wonderful code repository. It really helps me a lot.

I have tried converting many different types of images and it is working quite well, but I have found one case where it detects the wrong contour. When I pass the image with little or no background at that time it detects the wrong contour.

here is the source image, 8

here is the final transformed image, 8

It detected the wrong contour.

Can you please guide me to resolve this issue.

Thanks in advance.

You could try using the interactive mode using the -i flag and manually tune the dimensions
