Query: Across-scale Process Similarity based Interpolation for Image
  Super-Resolution   A pivotal step in image super-resolution techniques is interpolation, which
aims at generating high resolution images without introducing artifacts such as
blurring and ringing. In this paper, we propose a technique that performs
interpolation through an infusion of high frequency signal components computed
by exploiting `process similarity'. By `process similarity', we refer to the
resemblance between a decomposition of the image at a resolution to the
decomposition of the image at another resolution. In our approach, the
decompositions generating image details and approximations are obtained through
the discrete wavelet (DWT) and stationary wavelet (SWT) transforms. The
complementary nature of DWT and SWT is leveraged to get the structural relation
between the input image and its low resolution approximation. The structural
relation is represented by optimal model parameters obtained through particle
swarm optimization (PSO). Owing to process similarity, these parameters are
used to generate the high resolution output image from the input image. The
proposed approach is compared with six existing techniques qualitatively and in
terms of PSNR, SSIM, and FSIM measures, along with computation time (CPU time).
It is found that our approach is the fastest in terms of CPU time and produces
comparable results.
