Journal ArticleDOI
Single-frame image super-resolution using learned wavelet coefficients
TL;DR: A single‐frame, learning‐based super‐resolution restoration technique by using the wavelet domain to define a constraint on the solution and an appropriate smoothness prior with discontinuity preservation in addition to the wave let‐based constraint to estimate the super‐resolved image.
Journal ArticleDOI
Single-frame image super-resolution through contourlet learning
C. V. Jiji,Subhasis Chaudhuri +1 more
TL;DR: A learning-based, single-image super-resolution reconstruction technique using the contourlet transform, which is capable of capturing the smoothness along contours making use of directional decompositions, which outperforms standard interpolation techniques as well as a standard (Cartesian) wavelet-based learning.
Journal ArticleDOI
Visual inspection and characterization of external corrosion in pipelines using deep neural network
TL;DR: The proposed deep learning approach effectively wards off the need for manual inspection and other non-vision based non-destructive evaluation techniques for pipeline corrosion which are cost ineffective and interrupts the functioning of pipelines.
