Apply blur or sharpen to image, excluding edges.

Hello,

I am overlaying a creative border to a photograph. The hole in the border is transparent so the photo remains visible. The border extends to the edge of the canvas of the photo. All is good, but there is a white edge of pixels at the inner and outer edge of the border. I'm assuming this is a result of the blur and/or sharpening to the border in areas where there is no pixel information. I have set all operations to channel rgba. Is there a way to eliminate this white edge of pixel and keep the it unaffected by the blur and/or sharpening?

Any help is appreciated!

Update: I was able remove the white edge of the outside border, as it was related to another issue. The white edge of pixel at inner border edge still remains.

Sample images, and the exact command you used, would help us understand.

Also please say what version IM you are using, on what platform.
