HiFST
Spatially-Varying Blur Detection
Based on Multiscale Fused and Sorted Transform Coefficients of Gradient
Magnitudes
S. Alireza Golestaneh, and Lina J. Karam
Here we
propose a novel effective approach to address the blur detection problem from a single image without requiring any knowledge about the
blur type, level, or camera settings. Our approach computes blur
detection maps based on a novel High-frequency multiscale Fusion and
Sort Transform (HiFST) of gradient magnitudes.
