Vibha Aggarwal, Manjeet Singh Patterh . Study of some Non-Linear Transforms for ECG Image Compression. International Conference on Recent Advances and Future Trends in Information Technology (iRAFIT 2012). IRAFIT, 1 (April 2012), 25-28.
Out of the many non-linear transform methods the paper is making use of the (i) Essentially Non-Oscillatory cell-average decomposition (ENOCA), (ii) Max-lifting morphological wavelet transform (Maxlift), (iii) Med-lifting morphological wavelet transform (Medlift) and (iv) Morphological Haar wavelet transform (Mhaar) for ECG image compression. This study aims at recreating the image using inverse transforms after compressing the ECG image by making the use of the above mentioned transforms. There is an inversely proportionate relationship between image quality and image compression. This study has been undertaken not for the purpose of quantization and encoding rather an effort is being made to compare the different transform methods for ECG image compression.
