Recently the wavelet-based contourlet transform (WBCT) is adopted for image coding
because it matches better image textures of different orientations. However, its …

多重解析度方向性轉換包含頻率領域和空間領域兩方面. 在頻率領域的多重解析度方向性轉換中
, 以小波轉換為基礎的輪廓轉換能針對影像中的紋路方向, 提供較佳的配合度 …

In this paper, we propose an adaptive wavelet coding scheme. A decision method is
designed to identify whether the LH, HL, and HH wavelet subbands are suitable for …

In this paper, we propose an image coding approach using wavelet-based adaptive
contourlet transform. The approach adopts the wavelet transform to implement subband …

The interest in coding was very high because it is widely relied on in the security of
correspondence and in the security of information in addition to the need to rely on it in the …

In this tutorial, we will briefly review the wavelet transform and the separable 2D wavelet
transform. Although the wavelet transform is widely used in many signal and image …
