| This paper discusses the application of complex discrete wavelet transform (CDWT) which has significant advantages over real wavelet transform for certain signal processing problems. CDWT is a form of discrete wavelet transform, which generates complex coefficients by using a dual tree of wavelet filters to obtain their real and imaginary parts. The paper is divided into three sections. The first section deals with the disadvantage of Discrete Wavelet Transform (DWT) and method to overcome it. The second section of the paper is devoted to the theoretical analysis of complex wavelet transform and the last section deals with its verification using the simulated images. |
