•This paper proposes a method for constructing the combined cubic surface. A quadratic polynomial surface patch is first constructed in the 3 × 3 (2 × 2) region centered on each pixel. Then the effect of each coefficient on low frequency and high frequency information is researched. First calculate the coefficient that has a large effect on the low-frequency information, and then calculate the coefficient that has a greater effect on the high- frequency information. All quadratic surface patches are weighted to form the cubic surface.•This paper proposes an efficient method for constructing the initial cubic polynomial surface fitting to the input image with the constraint of local features (such as image edges and textures) and distance. By sampling the initial surface, the initial high-resolution image with higher precision and better visual effect can be obtained.•This paper proposes an efficient method for constructing error high-resolution image to modify initial high-resolution, including calculating error high-resolution image and constructing the cubic surface with higher precision to smooth error high-resolution image.•This paper proposes an efficient method that combines non-local similarity iteration optimization with secondary filtering to optimize the error high-resolution image. |
