Fixing a blurry, low-resolution logo without redrawing it

How sub-pixel edge reconstruction recovers smooth shapes from tiny, blurry or pixelated logos — and where the limits are.

A 96-pixel logo is not hopeless. The blur you see is anti-aliasing, and anti-aliasing is information: a pixel that is 40 % blue and 60 % white tells you the edge crosses it at a particular position. Curvora turns every such pixel into a membership value, builds a continuous field, and extracts the boundary from the field — not from the pixel grid.

Pixelated (nearest-neighbour) logos

If the logo was enlarged with hard, blocky pixels, the engine detects the block size, collapses the image back to its true resolution, and reconstructs from real pixels. The result is smooth where the original was smooth — without inventing detail that never existed.

What it cannot do

A three-pixel-wide letter has too little information for exact serifs. Curvora reconstructs what is supported by the pixels; it does not hallucinate. When you need more than that, the honest path is to redraw from the reconstruction, which is far faster than starting from nothing.
