Wavelet based Image Reconstruction from Gradient Data

October 2014
This toolbox can be used to reconstruct an image (2-D signal) from gradient (first order derivative) data. Reconstructing the signal from the gradient domain is a required step in applications based on gradient manipulations, such as high dynamic range compression, image stitching, image editing, image fusion, etc.
We recommend that you start by looking at the Examples.pdf documentation. There are included three examples of how the main function (ImageRecH.m) can be used, depending on the context (e.g., grayscale image reconstruction, colour image reconstruction, grayscale image reconstruction from noisy gradient data). The code used to generate the examples is Examples.m
