Description

Demonstration of denoising with the Edge Adptive Directional Total Variation(EADTV), Modified by Yuanquan Wang, Nov.9,2012, when I saw the following DTV paper: Bayram, I., and Kamasak, M.E., "Directional Total Variation," IEEE Signal Processing Letter, vol.19, No.12, pp. 781-784,2012. In the proposed EADTV model, the direction is adaptive to the image edge direction, so that the EADTV model can preserves several dominant directions in the image, while the DTV model can just preserve one dominant direction.
we will further extend the EADTV for color image in near future.

it is exciting that the work on EADTV is now published in IET the Journal of Engineering, in an open access model. but this paper is free of charge since I have no funding.

one can extend this model for color image, texture image!

Dear BMV: Many thanks for your interest in our work!

ISRGB: This function is obsolete and may be removed in future versions.

if the matlab version is too high, the function ISRGB is not no longer valid. we use this function to transfer the RGB image to GRAY image, one can delete the code and use other function, or directly read into a gray image.

the filename 'fig3.bmp' may be changed to other file one used.
