Consider a discrete 'blurred' output $h[t]$ given by the convolution of filter $f[t]$ and signal $g[t]$. This question considers recovering $g[t]$ from a window (subset) of $h[t]$. This causes the problem to be under-determined.
My understanding is that most approaches are based on regularisation however most sources s... | CommonCrawl |
