A Novel Image Reconstruction Algorithm Based

on Concatenated Dictionary



This paper presents a novel method for image

reconstruction, which decomposites the image by

concatenating a redundant dictionary of several bases and

then reconstruct the image efficiently by means of Matching

Pursuit algorithm. The proposed method constructs the

concatenated dictionary with cosine bases, wavelet bases

and contourlet bases, which will lead to a better

approximation of the original image. The experimental

results show that the proposed algorithm can greatly reduce

the computational complexity and generate a better

reconstruction effect compared with previous methods.-A Novel Image Reconstruction Algorithm Based on Concatenated Dictionary This paper presents a novel method for image reconstruction, which decomposites the image by concatenating a redundant dictionary of several bases and then reconstruct the image efficiently by means of Matching Pursuit algorithm.
