Local Binary Pattern Guided Bilateral Spatial Error Reconstruction
نویسندگان
چکیده
In many communication occasions, packet loss or data corruption often occurs. Data incompleteness results in video degradation, which greatly affect visual quality. Error concealment is needed for the robustness of video transmission. In this paper, we introduce a local binary pattern guided bilateral spatial error concealment. In the computation of local search window, neighboring local binary patterns are computed. The computed binary value is forwarded to bilateral distance weight framework. In bilateral weight computation framework, geometric distance of neighboring patches is replaced by Hamming distance of neighboring local binary patterns. Finally, favorable results of the proposed algorithm are shown in experiments comparing with several competitors.

Second-Order Statistical Texture Representation of Asphalt Pavement Distress Images Based on Local Binary Pattern in Spatial and Wavelet Domain
Assessment of pavement distresses is one of the important parts of pavement management systems to adopt the most effective road maintenance strategy. In the last decade, extensive studies have been done to develop automated systems for pavement distress processing based on machine vision techniques. One of the most important structural components of computer vision is the feature extraction met...
متن کاملProposing an effective approach for Network security and multimedia documents classically using encryption and watermarking
Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...
متن کاملLocal gradient pattern - A novel feature representation for facial expression recognition
Many researchers adopt Local Binary Pattern for pattern analysis. However, the long histogram created by Local Binary Pattern is not suitable for large-scale facial database. This paper presents a simple facial pattern descriptor for facial expression recognition. Local pattern is computed based on local gradient flow from one side to another side through the center pixel in a 3x3 pixels region...

Background: Osteoporosis is a systemic skeletal disease characterized by low bone mineral density (BMD) and micro-architectural deterioration of bone tissue, leading to bone fragility and increased fracture risk. Since Panoramic image is a feasible and relatively routine imaging technique in dentistry; it could provide an opportunistic chance for screening osteoporosis. In this regard, numerous...
متن کاملTexture-based Segmentation of High-Resolution Remotely Sensed Imagery for Identification of Fuzzy Objects
In this study, we discuss a supervised texture-based image segmentation algorithm. We apply this algorithm to airborne high-resolution elevation (LiDAR) and multi-spectral imagery (CASI) of a coastal area on the northwest coast of England. Texture is modelled with the joint distribution of the Local Binary Pattern (LBP) operator and local variance. Spatial objects are derived from the imagery b...
