Possible minor error in sentence: "zero padding" -> "padding"

[hmf]

In the second last sentence of section 2.2 we have:

In practice, two specific instances of zero padding are used quite extensively because of their respective properties.

I suspect it should be:

"In practice, two specific instances of zero padding are used quite extensively because of their respective properties."

Edit:
The fist section of chapter 3 states:

Since pooling does not involve zero padding, the relationship describing the general case is as follows:

I think this should also be:

"Since pooling does not involve zero padding, the relationship describing the general case is as follows:"

or maybe "non-zero" padding?

or maybe:

"Since pooling only involves zero padding, the relationship describing the general case is as follows:"

Seemed to have misunderstood the term. Zero here refers to the value that is used to pad, not the size of the padding.
