On Evaluating Video Object Segmentation Quality: A Perceptually Driven Objective Metric

Touradj Ebrahimi, Elisa Drelie Gelasca

The task of extracting objects in video sequences emerges in many applications such as object-based video coding (e.g., MPEG-4) and content-based video indexing and retrieval (e.g., MPEG-7). The MPEG-4 standard provides specifications for the coding of vid ...

Watermarked 3D Mesh Quality Assessment

Touradj Ebrahimi, Elisa Drelie Gelasca

This paper addresses the problem of assessing distortions produced by watermarking 3D meshes. In particular, a new methodology for subjective evaluation of the quality of 3D objects is proposed and implemented. Two objective metrics derived from measures o ...

On Evaluating Video Object Segmentation Quality: A Perceptually driven Objective Metric

Touradj Ebrahimi, Elisa Drelie Gelasca

Segmentation of moving objects in image sequences plays an important role in video processing and analysis. Evaluating the quality of segmentation results is necessary to allow the appropriate selection of segmentation algorithms and to tune their paramete ...

On Evaluating Metrics For Video Segmentation Algorithms

Touradj Ebrahimi, Elisa Drelie Gelasca

Evaluation is a central issue in the design, implementation, and performance assessment of all systems. Recently, a number of metrics have been proposed to assess the performance of segmentation algorithms for image and video data. This paper provides an o ...

Quality assessment is a central issue in the design, implementation, and performance testing of all systems. Digital signal processing systems generally deal with visual information that are meant for human consumption. An image, a video, or a 3D model may ...

To determine Regions of Interest (ROI) in a scene, percep-tual saliency of regions has to be measured. When scenes are viewed with the same context and motivation, these ROIs are often highly correlated among different people. As a result, it is possible t ...

In this paper an objective metric to measure the perceptual quality of watermarked 3D meshes is presented. The metric relies on a multiscale measurement of the roughness of 3D meshes before and after the watermark insertion. The validity of the proposed me ...

Objective Evaluation of the Perceptual Quality of 3D Watermarking

Touradj Ebrahimi, Elisa Drelie Gelasca

In this paper an objective metric to measure the perceptual quality of watermarked 3D meshes is presented. The metric, which is based on a black-box approach, relies on the measurement of the roughness of 3D meshes before and after the insertion of the wat ...
