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 کاملHierarchical rotational invariant similarity measurement for MPEG-7 homogeneous texture descriptor - Electronics Letters
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. T...
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 کاملAn efficient computation method for the texture browsing descriptor of MPEG-7
In this paper, an efficient computation method for computing the texture browsing descriptor of MPEG-7 is provided. Texture browsing descriptor is used to characterize a texture’s regularity, directionality and coarseness. To compute the regularity of textures, Fourier transform is first performed. To get more discriminative features for regularity computation, the Fourier spectrum is treated a...
متن کاملFast Mode Decision for H.264/AVC Based on Clustering of MPEG−7 Texture Descriptor Values
As multimedia content is rapidly increasing everyday, the availability of indexing metadata such as MPEG−7 descriptors becomes increasingly important for accessibility purposes. However, the use of this indexing metadata in improving coding efficiency has rarely been explored. A novel fast mode decision algorithm for H.264/AVC encoders based on the use of an MPEG−7 descriptor is proposed in thi...
