• True

• False

A 3x3 median filter is a linear filter

• True

• False

The 1x1 filter [-1] is a linear filter

• True

• False

The 1x3 horizontal derivative filter is a linear filter

• True

• False

We can combine the horizontal and vertical derivative filters into a single 3x3 filter, which provides the directed edge strength

• True

• False

If we repeatedly apply a smoothing filter, the smoothing effect will be stronger

• True

• False

Correlation of image I with the given 3x3 filter produces the image I' which is identical to I but all pixels have shifted one pixel up and one pixel left.

• True

• False

Convolution of image I with the given 3x3 filter H*(i,j) produces the image I' which is identical to I but all pixels have shifted one pixel up and one pixel left.

• True

• False
