Directional cubic convolution interpolation (DCCI) is an edge-directed image scaling algorithm created by Dengwen Zhou and Xiaoliu Shen.[1]
By taking into account the edges in an image, this scaling algorithm reduces artifacts common to other image scaling algorithms.[which?] For example, staircase artifacts on diagonal lines and curves are eliminated.
The algorithm resizes an image to 2x its original dimensions, minus 1.[citation needed]
