README Multiscale Sparsity Based Tomographic Denoising (MSBTD) Main.m: the file to run the software Instructions how to use the GUI_interface Step 1: click the 'open test' button to input the test noisy image and click the 'open averaged'button to input the averaged image Step 2: setting the parameters for MSBTD method. (the default parameters are used in our method, but you can tune it yourse) Step 3: click the 'MSBTD method'to run MSBTD and click the 'Tikhonov method'to run the Tikhonov for comparison (visually denoised results will be automatically shown in the top left and the PSNR results will also be shown in bottom left) Step 4: click the 'save' button to save the results as the .tif or .mat format Step 5: compute the MSR by select a region from the test image (click the buttion 'select a region from the test image') Step 6: compute the CNR by first select a background region from the test image (click the buttion 'select a background region from the test image') and then select the foreground region from the test image (click the buttion 'select a foreground region from the test image') DEVELOPED FOR THE PAPER "Sparsity Based Denoising of Spectral Domain Optical Coherence Tomography Images", Leyuan Fang,Shutao Li,Qing Nie,Joseph A.
