'haar_wt' function take a grey image and a value 'delta' as inputs and outputs a compressed image. Haar wavelet transformation was used as a transformation matrix for compression process. 'haar_wt_rgb' does the same for an RGB image. In here, 'delta' value governs the compression ratio. 'delta' is a value between 0 and 1, when delta=0, no compression is done. These functions can be considered as a starting point for analysis of Haar wavelet transformation based image compression. Implementation was based on following source.
