    4. Automated segmentation algorithm for detection of changes in vaginal epithelial morphology using optical coherence tomography

      Automated segmentation algorithm for detection of changes in vaginal epithelial morphology using optical coherence tomography
      We have explored the use of optical coherence tomography (OCT) as a noninvasive tool for assessing the toxicity of topical microbicides, products used to prevent HIV, by monitoring the integrity of the vaginal epithelium. A novel feature-based segmentation algorithm using a nearest-neighbor classifier was developed to monitor changes in the morphology of vaginal epithelium. The two-step automated algorithm yielded OCT images with a clearly defined epithelial layer, enabling differentiation of ...

    5. Retinal optical coherence tomography image enhancement via shrinkage denoising using double-density dual-tree complex wavelet transform

      Retinal optical coherence tomography image enhancement via shrinkage denoising using double-density dual-tree complex wavelet transform
      Image enhancement of retinal structures, in optical coherence tomography (OCT) scans through denoising, has the potential to aid in the diagnosis of several eye diseases. In this paper, a locally adaptive denoising algorithm using double-density dual-tree complex wavelet transform, a combination of the double-density wavelet transform and the dual-tree complex wavelet transform, is applied to reduce speckle noise in OCT images of the retina. The algorithm overcomes the limitations of ...

    11. Wavelet denoising during optical coherence tomography of the prostate nerves using the complex wavelet transform

      Wavelet denoising during optical coherence tomography of the prostate nerves using the complex wavelet transform
      Preservation of the cavernous nerves during prostate cancer surgery is critical in preserving sexual function after surgery. Optical coherence tomography (OCT) of the prostate nerves has recently been studied for potential use in nerve-sparing prostate surgery. In this study, the discrete wavelet transform and complex dual-tree wavelet transform are implemented for wavelet shrinkage denoising in OCT images of the rat prostate. Applying the complex dual-tree wavelet transform provides improved results ...
