A novel objective measure for assessing the quality of image in-painting is proposed. In contrast to standard image quality metrics, the proposed one takes into account some constraints and characteristics related to the specific goals of inpainting techniques. The idea is to combine spatial low-level features and perceptual criteria in the design of the(More)
Recently, digital image inpainting has attracted strong research interest because of its extensive applications in real life. The terminology “inpainting” refers to automatic restoration of image defects such as scratches or blotches as well as removal of unwanted objects as, for instance, subtitles, logos, etc, such that it is undetectable by(More)
Recently, image completion or inpainting has become a hot research topic because of its extensive applications in various real-world applications. Many papers have been published on this topic, but there are very few studies devoted to objective image inpainting evaluation. The intend of this work is to propose a solution based on Image Quality Metrics(More)
The increasingly use of digital images in our daily life and the availability of powerful software for processing and editing images, open new challenges regarding illegal or unauthorized image manipulation. Thus, it becomes essential to authenticate digital copies, validate their content, and detect possible forgeries. In this paper, we focus on detection(More)
Image inpainting is not only the art of restoring damaged images but also a powerful technique for image editing e.g. removing undesired objects, recomposing images, etc. Recently, it becomes an active research topic in image processing because of its challenging aspect and extensive use in various real-world applications. In this paper, we propose a novel(More)
A new Image Quality Metric (IQM) dedicated to image in-painting evaluation is proposed in this paper. This objective measure is computed by combining some structural and salient features related to the specific goals of inpainting purposes. The main perceptual characteristics used in this approach are the visual coherence and the visual saliency. The(More)
Digital image inpainting technique could provide substantial support for future restoration of images. However, much less effort has been devoted to the development of image inpainting evaluation. In this paper, we proposed a novel objective metric for assessing the quality of color image inpainting which takes into account some constraints and(More)
The electrocardiogram inverse problem is a non-linear and ill-posed problem for which it is very difficult to find an exact solution. In this paper, we presented an efficient and robust method to solve this problem. The heart activity is modeled by a single moving dipole and the human body is considered as finite volume conductor constructed based on an(More)
