Texture Descriptors in MPEG-7
نویسندگان
چکیده
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 of the texture and are useful for image retrieval application, while HTD is for homogeneously textured region and EHD is for multi-textured natural image or sketch. PBD is a compact descriptor suitable for quick browsing application.

Evaluation 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 کاملEmpirical Evaluation of MPEG - 7 Texture Descriptors with A Large - Scale Experiment
This paper conducts an empirical evaluation of the MPEG-7 texture descriptors and the LBP (Local Binary Pattern) operator. The experiment involves 319 textures from the Outex texture database, which makes it one of the largest experiments found in the literature, if not the largest, in terms of the number of texture classes. The descriptors are evaluated with respect to retrieval performance an...
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 کاملMultimedia Content Filtering, Browsing, and Matching Using MPEG-7 Compact Color Descriptors
This paper presents two compact color feature descriptors that have been accepted to the working draft of MPEG-7, the ongoing activity to standardize multimedia content descriptions. The need for content description arises from the increase in the number of broadcast channels and the availability of a large number of video content over the Internet. Without such descriptions, the average consum...
متن کاملMPEG-7 Visual Descriptors and Discriminant Analysis
The MPEG-7 standards defines a set of descriptors to characterize the content of visual media [l, 2]. These visual descriptors, such as color and texture descriptors, have undergone extensive evaluation and development based on the application of retrieval ranking. Specifically, under query-by-example (QBE) paradigm, average normalized modified retrieval rank (ANMRR), a rate-accuracy like perfo...
