TDA2: How to calculate the border pixels count for an image block.

Part Number:TDA2

Hi,

I have read the pdf attached in the following thread.

e2e.ti.com/.../734522

I have a doubt in that.

In slide no.16, I have read the paragraph:

Offset to next block is not necessarily equal to block width in order to transfer overlapping blocks.
Overlapping blocks are used in case of filtering to account for the overlapping border pixels. For
instance a N taps filter needs N-1 border pixels. The border width would be (N-1)/2 pixels.
Example:
Offset to next block= w
block_width= w + N-1


I just want to know, how to calculate the block_width for a 16*16 image block, by using the mentioned formula?

It means, the number of border pixels , I need to add with the original image block.

Regards,

Surbhi
