Abstract:
In this paper, we propose an image coding scheme based on a wavelet-like transform derived from orthogonal polynomial basis. First, 2D non-separable wavelet functions are derived from a set of bivariate orthogonal polynomials. Then, a wavelet-like transform coding scheme using the proposed wavelet functions is proposed. The motivation behind using orthogonal polynomials is that they exhibit some properties related to the human visual system (HVS) [1]. After applying the proposed transform, the obtained coefficients are threshold coded using quantization and bit allocation as in JPEG baseline system. The performance of the proposed transform coding method is reported. The proposed coding scheme is also compared with other transform coding methods such as JPEG, JPEG2000 and JPEG-XR/HDPHOTO.
