Detect the form of the input blur matrix, G
1 | detectBlur(G)
|
G |
The input blur matrix to be analysed and checked whether it corresponds to direct blur or box.car blur. |
Detects if the input blur matrix, G, has uniform structure in being of direct blur type everywhere or box.car type everywhere. In those cases, it will return a character string 'direct' or 'box.car' respectively, otherwise it returns 'smooth'. This is done in the direct blur case by checking that the mvfft(G) is equal to 1 everywhere (complex part is zero everywhere) and in the box.car case by checking that each column has two unique values, a zero and positive value. If the blur type is not identified to be direct or box.car, the string 'smooth' is returned.
