Hi

STeven is possible to know what mathematical equation is behind Perspective correction that is used in this module?

Thanks

Blaz,

We can't just write out the formula but we can give you a hint. Think of what the image might look like if you started at the bottom of the image and as you proceed up each line you would stretch the entire line slightly such that if the bottom line is 320 pixels the next line up would be 322 (stretch it by 2 pixels) and so on. The stretch factor is the amount of perspective correction.

Note that this assume linear perspective.

STeven.
