It is known that several techniques for real-time implementation of perfect linear phase IIR filters have been developed, achieving higher computational efficiency than conventional FIR filters with similar performance. This paper presents new method

This paper presents a method for designing a 6th-order two-channel linear-phase IIR filter bank with quasi-power complementary characteristics for image subband coding. The lowpass filter is specified to have a double or quadruple zero at ω = π and

This paper proposes a new scheme for image coding using the wavelet transform. We decompose the original image into seven subbands with a two-level tree-structured filter bank. Vector quantization is applied to the coefficients of the high-frequency

In lossless image compression, a ladder network is commonly or widely used for integer to integer transform(integer transform), where rounding operations after multiplications cause some difference between the real and integer transform (transform er

In Digital audio processing, there are multiple standard sampling rates, for example, 48kHz for studio work, 44.1kHz for compact disk(CD) mastering. Therefore, sampling rate conversion is needed to interchange signals from one field to another. A rat

Natural images often consist of many different regions in intensity variation feature. The block adaptive predictors in lossless image coding often show considerably different entropies of block prediction errors between the horizontal scanning and t

In this paper, we propose a new effective lossless predictive image coding scheme. It intends to reduce the entropy of the prediction error images by an additional nonlinear processing. First, we use a block adaptive prediction scheme (BAP). The resu
