Abstract: ABSTRACT Dimensionality reduction algorithms are widely applied to high-dimensional data pre-processing, especially for face images. In this paper, we propose an unsupervised sparse subspace learning approach called weighted sparse neighbourhood-preserving projections (WSNPP) for face recognition.… read more here.

Abstract: Abstract. We present a nonlocal weighted sparse representation (NWSR) method for reconstruction of retinal optical coherence tomography (OCT) images. To reconstruct a high signal-to-noise ratio and high-resolution OCT images, utilization of efficient denoising and interpolation… read more here.

DOI: 10.3390/e24010096
Abstract: Synthetic aperture radar (SAR) images are inherently degraded by speckle noise caused by coherent imaging, which may affect the performance of the subsequent image analysis task. To resolve this problem, this article proposes an integrated… read more here.
