optical coherence tomography (oct) uses the spatial and temporal coherence properties of optical waves backscattered from a tissue sample to form an image. an inherent characteristic of coherent imaging is the presence of speckle noise. in this study we use a new ensemble framework which is a combination of several multi-layer perceptron (mlp) neural networks to denoise oct images. the noise is...

Redaction is the process of removing privileged information from a document before it is presented to other parties. This paper discusses the major issues associated with the redaction of digital information from electronic devices. A novel technique involving a tokenized representation is presented as a solution to digital redaction in legal proceedings.

Introduction:  The  success  of  hyperthermia  depends  on  the  accuracy  of  the  temperature  monitoring in the tumor and the surrounding normal tissue. In this study, the temperature changes  were determined by computing the speckle displacement in the ultrasound digital images. Speckle  tracking algorithm was used to compute the displacement.  Materials and Methods: The experiment was perf...

It has been recently demonstrated, in dramatic fashion, that sensitive information thought to be obliterated through the process of redaction can be successfully recovered via a combination of manual effort, document image analysis, and natural language processing techniques. In this paper, we examine what might be revealed through redaction, exploring how known methods might be employed to det...

The prevalence of image and video capture along with public demand to view such recordings has made privacy protection a major concern. Redaction is used to obfuscate personally identifiable information such as faces, license plates, house numbers, and store fronts. Redaction aims to obfuscate targeted areas while maintaining scene context. We propose facial obfuscation methods that maintain co...
