Why does object removal leave a blurry patch?

Why it happens

ZURAPIC's Object Remover fills the erased area using content-aware fill: it copies small patches of texture from elsewhere in the photo and stitches them into the hole. It works well when the surrounding area has enough repeating detail — grass, brick, fabric, skin — to convincingly extend.

It struggles when the object removed a large area, was sitting in front of something with very little distinct texture (a plain sky, a smooth wall, an out-of-focus background), or was near the edge of the frame where there's less surrounding material to sample from. With too few good matches, the algorithm falls back to blending nearby pixels together, which is what produces that smeared, blurry look instead of a clean fill.

How to fix it in ZURAPIC

1. Increase the Search value. This controls how far the algorithm looks for matching texture — widening it gives it more material to draw from, especially useful on plain backgrounds where the nearest good texture might be further away than the default radius.
2. Increase Passes for higher quality. More passes let the algorithm refine the fill several times over instead of settling for the first rough pass — worth the extra second of processing on a visible area.
3. Adjust Patch size — a smaller patch preserves finer detail (good for textured surfaces like fabric or foliage); a larger patch is steadier on flatter areas but can look smoother/softer.
4. Switch to the AI fill model if the classic algorithm still struggles — it's built for exactly this case: large removed areas or scenes where there's simply no good local texture to copy from, since it generates plausible detail instead of only copying existing pixels.
