I am working with a digitized land use image that classifies land use by color. Land use is also divided by black lines that are about 10 pixels in width. I would like to remove these black lines so that land type changes are represented only by color change. What is the best way to remove the black lines?
I guess you might be able to select the black lines and fill with the appropriate color or use the brush or pencil tool to paint over the black lines.
A screenshot of the image or least enough of the image to show some of the areas in question might yeild some more specific answers.
You could select the areas of color. expand the selection by half the width of the black lines, and then fill the selections with the appropriate color.
You'd still have to do some touching up to get rid of all the black.
If the lines are a consistent width, you could select the lines (e.g., using Magic Wand and Contiguous selection), then Filter - Other - Maximize, 5 pixels.
