Abstract: High quality color image obliged expansive measure of space to store and extensive data transmission to transmit it. Because of impediments in data transfer capacity and away space, it is primary prerequisite to layers computerized color image. To meet this, various picture pressure procedures are created in last a few years. This research paper presents a peculiar Hybrid Wavelet Transform technique for Image compression using three orthogonal transforms. The concept of hybrid wavelet transform is to combine the attributes of two or more different orthogonal transform wavelet to attain the vitality of multiple transform wavelet. Proposed approach is to generate hybrid wavelet transform with three orthogonal transform using together which are Discrete Cosine transform, Discrete Wavelet transform and Discrete Kekre Transform. These all are lossy compression techniques. On several image simulation has been carried out. The experimental result has shown that hybrid transform wavelet performance is best as compared to transform wavelets. Here the hybrid of DWT, DCT and DKT provides the best result amongst the individual mentioned transforms.
