ABSTRACT This paper deals with the reconstruction of original image structure in the presence of local disturbances such as specular re∞ec- tions. It presents two novel schemes for their elimination with respect to the local image structure: an e-cient linear interpolation scheme and an iterative fllling-in approach employing anisotropic difiusion. The al- gorithms are evaluated on images of the heart surface and are suited to support tracking of natural landmarks on the beating heart.

    ABSTRACT: Specular reflections strongly affect the appearance of images, and usually hinder the computer vision algorithms applied to them. This is particularly the case with uterine cervix images. The highlights created by specular reflections are a major obstacle in the way of automatic segmentation of such images. We propose a method for the detection of specularities in cervix images that utilizes intensity, saturation and gradient information. A two-stage segmentation process is proposed for the identification of highlights. First, coarse regions that contain the reflections are defined. Second, probabilistic modeling and segmentation is used to achieve a precise segmentation inside the coarse regions. The resulting regions are filled by propagating the surrounding color information. The efficiency of the method for cervix images is demonstrated.

    ABSTRACT: This paper deal with efficient approach for reconstruction of arteries in heart image which is affected by disturbances such as specular reflections. Reconstruction schemes are sufficiently general for application in other fields, where disturbances in images should be eliminated ensuring continuity of local structures. Using histogram equalizing technique an efficient approach has been made for finding genuine specular reflected area in the heart image and filling those reflection affected area with the surrounding texture of heart surface. The continuity of the arteries in specular reflected area can be generated in image using interpolation technique. The smooth reconstruction of those areas can done by ensuring continuity of local structures using anisotropic diffusion and bilateral filtering.
