In this work, we incorporated the Feature Refinement (FR) scheme into the Self-supporting Tailored k-space Estimation for Parallel imaging reconstruction (STEP) image reconstruction framework to enhance its capability for structural representation in image domain, and developed a novel Weber Local Descriptor (WLD) method to improve the extraction of local image boundaries. With the preliminary experiments, it has been demonstrated that the improved STEP with WLD FR scheme can provide more accurate estimation of image details in comparison to original STEP and existing classic method.
