Actually no, I am happy with my results for JPEG images. This is not a filter similar to Gaussian blur, InkSketch etc. And I guess my plugin is of no use to anyone. To understand what I am trying to do, go to Tom Gibara's page and set Iterations = 1, Reduction = 0, Quantization = 0. That is what I am trying to do. Look how the image is Haar transformed and then inverse Haar transformed to retrieve the original image again. This technique is widely used in image compression algorithms like JPEG2000 and other formats. (JPEG used DCT or discrete cosine transform but the newer JPEG2000 uses DWT or discrete wavelet transform, and Haar transform is one type of DWT).
