Abstract(in English) | Directional cubic convolution interpolation is a highly accurate image upsampling method considering edge directions. In this method, firstly, some pixels are interpolated from the original pixels, and then, the remaining pixels are interpolated from the original pixels and the interpolated pixels. Thus each pixel has computational dependency, and when directional cubic convolution interpolation is implemented naively, its computational scheduling is inefficient. Therefore, we optimized the computation order and data arrangement of pixels to the form that makes it easy to apply loop fusion and vector operations, thereby speeding up. |
