Question

Cropped Only character from Image and remove spaces

I am trying to remove extra spaces from left and right of character image through opencv .Every image has different dimension .Is there any way to crop or remove extra spaces from left and right only or fetch only character from image.

Answer 1

Under the assumption that all your images look like the examples provided you can go with HansHirse's solution.

Segment the image into fore- and background using a global threshold. Then find the extreme coordinates of foreground pixels to define the boundaries of your sub image.

Of course you can do both steps on the fly instead of doing two iterations over your image.

Another solution: Use a blob detector to find the character components and merge their bounding boxes.
