What is Stride? What is the effect of high Stride on the feature map?

[vishrut-singhal]

Stride refers to the number of pixels by which we slide over the filter matrix over the input matrix. For instance –

• If Stride =1, then move the filter one pixel at a time.
• If Stride=2, then move the filter two-pixel at a time.

Moreover, larger Strides will produce a smaller feature map.
