Recently the digital imaging applications is increasing significantly and it leads the requirement of effective image compression techniques. Image compression removes the redundant information from an image. By using it we can able to store only the necessary information which helps to reduce the transmission bandwidth, transmission time and storage size of image. This paper proposed a new image compression technique using DCT-Biorthogonal Wavelet Transform with arithmetic coding for improvement the visual quality of an image. It is a simple technique for getting better compression results. In this new algorithm firstly Biorthogonal wavelet transform is applied and then 2D DCT-Biorthogonal wavelet transform is applied on each block of the low frequency sub band. Finally, split all values from each transformed block and arithmetic coding is applied for image compression.
