چکیده
tions. Of course, many functions may not be found from corresponding filter bank forms, but we only needed to find some similar ones which were the convolutions of the filter banks to replace them. Fig. 1 shows the structure of the new dictionary functions. The impulse response at each node of this tree structure decides a 1D dictionary function, and these functions are illustrated in Fig. 2. The filter parameters are listed in Table 1.

MPEG-7 Homogeneous Texture Descriptor
MPEG7 standardization work has started with the aims of providing fundamental tools for describing multimedia contents. MPEG7 defines the syntax and semantics of descriptors and description schemes so that they may he used as fundamental tools for multimedia content description. In this paper, we introduce a texture based image description and retrieval method, which is adopted as the homogeneo...
متن کاملTexture Descriptors in MPEG-7
We present three descriptors of texture feature of a region. Namely, the homogeneous texture descriptor (HTD), the edge histogram descriptor (EHD), and the perceptual browsing descriptor (PBD). They are currently included in the Committee Draft of the MPEG-7 Visual (ISO/IEC 15938-3). Each descriptor has a unique functionality and application domain. HTD and EHD describe statistical distribution...
متن کاملEvaluation and comparison of texture descriptors proposed in MPEG-7
Texture description contributes as one of the most important low-level features in content-based image retrieval. In MPEG-7, homogeneous texture descriptor (HTD), texture browsing descriptor (TBD), and edge histogram descriptor (EHD) have been proposed as texture descriptors. However, no comprehensive evaluation and comparison of these three descriptors have been made. In this paper, we propose...
متن کاملColor and texture descriptors
This paper presents an overview of color and texture descriptors that have been approved for the Final Committee Draft of the MPEG-7 standard. The color and texture descriptors that are described in this paper have undergone extensive evaluation and development during the past two years. Evaluation criteria include effectiveness of the descriptors in similarity retrieval, as well as extraction,...
متن کاملContour Description using Wavelets
We have developed a description for contours of arbitrary objects, which combines the simple global description of moments with the hierarchical decomposition property of Wavelet analysis. An extraction algorithm for obtaining the required parameters for the proposed MPEG-7 Descriptors as well as a matching procedure for similarity search in image databases are described. For a fast search in l...
