If you blur image, you lose data. You can not restore it, so "deblurring" function don't exist (if I correctly understood this term)

You can try cv::normalize(), or addition contour to image for "improve" image

Or really you want "de(spot)ing" your image?

You can actually deblur if it comes from video, search for "blind deconvolution". There are some Matlab implementations around.

This is simply not true. Blurring does not destroy all data, and with the right math a great deal of detail can be recovered. Here is a python opencv program demonstrating it:
