    Instead of rendering black disks over a white background, this code renders smooth spots with a Gaussian profile over a white background. See the README.txt file in the archive and the dataset below.

    2DGridRender
    Matlab code (GPU / CPU code) for rendering 2D grids: 2DGridRender.tgz (last modified August 17th, 2023)
    To use it: download CheckerBoardRender then replace the functions in the functions directory by the corresponding ones in 2DGridRender.



    Datasets:

    Rendered by BSpeckleRender:

    figure3.tgz: data used to generate Figure 3 in the paper. Please consult readme.txt.

    sample1.tgz: eleven 512x512 8-bit speckle images translated by a n*0.1 pixel displacement, n being between 0 and 10. Generated by script_translation.m in the archive (the same as in BSpeckleRender.tgz).

    sample1b.tgz: eleven 512x512 8-bit speckle images translated by a n*0.1 pixel displacement, n being between 0 and 10. Generated by script_translation.m in the archive (different parameters).

    sample2.tgz: reference image and deformed image (512x512 8-bit images), inverse displacement distributed according to a modulated sine wave. Generated by script_modsinewave.m in the archive (the same as in BSpeckleRender.tgz).


    Rendered by BSpeckleRender_b:

    sample_a.tgz: two pairs of 12-bit 500x100 images generated by script_speckleBSR.m in the archive (the same as in BSpeckleRender_b.tgz). See README.txt to visualize the images in MATLAB.
