Inception of Hybrid Wavelet Transform using Two Orthogonal Transforms and Itís use for Image Compression

Abstract óThe paper presents the novel hybrid wavelet transformgeneration technique using two orthogonal transforms. Theorthogonal transforms are used for analysis of global propertiesof the data into frequency domain. For studying the localproperties of the signal, the concept of wavelet transform isintroduced, where the mother wavelet function gives the globalproperties of the signal and wavelet basis functions which arecompressed versions of mother wavelet are used to study the localproperties of the signal. In wavelets of some orthogonaltransforms the global characteristics of the data are hauled outbetter and some orthogonal transforms might give the localcharacteristics in better way. The idea of hybrid wavelettransform comes in to picture in view of combining the traits of two different orthogonal transform wavelets to exploit thestrengths of both the transform wavelets.The paper proves the worth of hybrid wavelettransforms for the image compression which can further beextended to other image processing applications likesteganography, biometric identification, content based imageretrieval etc. Here the hybrid wavelet transforms are generatedusing four orthogonal transforms alias Discrete Cosine transform(DCT), Discrete Hartley transform (DHT), Discrete Walshtransform (DWT) and Discrete Kekre transform (DKT). Tecomparison of the hybrid wavelet transforms is also done withthe original orthogonal transforms and their wavelet transforms.The experimentation results have shown that the transformwavelets have given better quality of image compression than therespective original orthogonal transforms but for hybridtransform wavelets the performance is best. Here the hybrid of DCT and DKT gives the best results among the combinations of the four mentioned image transforms used for generating hybridwavelet transforms.
