WitrynaTo eliminate the zero-padding artifacts around the edge of the image, imfilter offers an alternative boundary padding method called border replication. In border replication, the value of any pixel outside the image is determined by replicating the value from the nearest border pixel. This is illustrated in the following figure. WitrynaFirst, I think conv2 and imfilter will give you the same result if you change the filter option of imfilter to conv instead of corr.imfilter uses correlation to filter images by default that starts from one side of the image, whereas covolution starts from the other, so there may be some small differences in the filter output..
