摘要： An edge-oriented interpolation method is used for enlarging a source image. The region in which each destination pixel in an enlarged image is located is identified as a smooth region, a text region or an edge region, and Sobel edge detection for two adjacent pixels around the destination pixel is performed to obtain two Sobel gradients. When the destination pixel is located in a smooth region, cubic convolution interpolation is performed for the destination pixel with a first slope. When the destination pixel is located in a text region, cubic convolution interpolation is performed for the destination pixel with a second slope. When the destination pixel is located in an edge region, Sobel-based interpolation for the destination pixel is performed with the two Sobel gradients.
