Hi all. I get really annoyed when my beautifully sharp panorama is sullied and spoilt by a bit of camera-motion-blur in just one or two of the source images ... :-(
My ( innumerate ) understanding is that motion blur can be corrected by a) modelling the motion effect as a Point Spread Function [0] and then b) applying a Deconvolution [1] thingy to 'rebuild' – or 'remap' – the un-blurred pixels. >From my agonising experience, "camera-motion-blur" tends to be linear ( occasionally rotational ) and applies equally to every pixel in the frame. This should be quite easy to measure/model in a single image using a few manual control points ( eg for start and end points of a blur trail ) ? If the motion blurred image overlaps with a non-motion blurred image, it should be quite straight forward to automate motion blur correction. Note that only partial overlap is necessary for camera- motion-blur correction. Motion blur caused by moving objects – “object-motion-blur” – could use the same tools, but also requires some way of determining which pixels need correcting and which don't – a kind of object detection. I can't get my head around the deconvolution algorithms by which the blurred pixel values are rebuilt into not-blurred pixel, but the method may help pave the way toward support for resolution up-sampling by combining data from overlapping images ...
