We only consider the X positions (horizontal )right do not calculate for the y(verticle). I consider like that because the filter you used actually the convolution of the original types for X. I hope I could explain myself
Nice video but why using only horizontal edge gradient?, answer should be combining both gradient. this way you only detect one directional edge. G= |Gx| + |Gy| or u can take its Euclidian form with sq roots and sq.
@@collegefriendly okay maam, and if it is not mentioned then we need to match for each pixels with their respective neighbors even in sobel and prewitt filter, right??
When we have to do pixel replucation or zero padding and when to apply directly? Is it necessary to do zero padding/pixel replication before applying any filter? Please help me mam
