From: Super-resolution CT Image Reconstruction Based on Dictionary Learning and Sparse Representation
Profiles of different results for the horizontal line labeled in Fig. 6(a) in the 300th row of the clinical CT images. The true curve represents the profile of the original CT image. The interpolation results represent the profile of the reconstructed image achieved using the bicubic interpolation method. The sparse curve represents the profile of the image reconstructed using the proposed method with 8 iterations.
