Myself BLACK,doing my Engineering final year in PSP college.For my final year project i am working Medical image processing field.Now i want ideas regarding the article Non local means speckle filtering of ultrasound images using Bayesian framework.I have attached the abstract of the project.
Abstractâ€In image processing, restoration is expected to improve
the qualitative inspection of the image and the performance
of quantitative image analysis techniques. In this paper, an adaptation
of the nonlocal (NL)-means filter is proposed for speckle
reduction in ultrasound (US) images. Originally developed for
additive white Gaussian noise, we propose to use a Bayesian
framework to derive a NL-means filter adapted to a relevant
ultrasound noise model. Quantitative results on synthetic data
show the performances of the proposed method compared to
well-established and state-of-the-art methods. Results on real
images demonstrate that the proposed method is able to preserve
accurately edges and structural details of the image.
