Imaging motor recovery after stroke [PDF]

open access: yesNeuroRX, 2006
Most patients show improvement in the weeks or months after a stroke. Recovery is incomplete, however, leaving most with significant impairment and disability. Because the brain does not grow back to an appreciable extent, this recovery occurs on the basis of change in function of surviving tissues.

Blind Dual Watermarking Scheme Using Stucki Kernel and SPIHT for Image Self-Recovery

open access: yesIEEE Access, 2022
In this paper we propose a blind dual watermarking scheme using Set Partitioning in Hierarchical Trees (SPIHT) and Stucki Kernel halftone technique for the tamper detection and image self-recovery.

Underwater 2D Image Acquisition Using Sequential Striping Illumination

open access: yesApplied Sciences, 2019
Structured lighting techniques have increasingly been employed in underwater imaging, where scattering effects cannot be ignored. This paper presents an approach to underwater image recovery using structured light as a scanning mode.

Regularized Image Recovery in Scattering Media [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2007
When imaging in scattering media, visibility degrades as objects become more distant. Visibility can be significantly restored by computer vision methods that account for physical processes occurring during image formation. Nevertheless, such recovery is prone to noise amplification in pixels corresponding to distant objects, where the medium ...

Underwater Image Recovery Using Structured Light

open access: yesIEEE Access, 2019
Structured lighting techniques have increasingly been employed in underwater imaging. Except for the limitation in underwater illumination, the desire of underwater image acquisition comes from the applicability of removal of the back scattered light ...

Color Image Self-Recovery and Tampering Detection Scheme Based on Fragile Watermarking with High Recovery Capability

open access: yesApplied Sciences, 2021
In this paper, a fragile watermarking scheme for color image authentication and self-recovery with high tampering rates is proposed. The original image is sub-sampled and divided into non-overlapping blocks, where a watermark used for recovery purposes ...
