Lagrange-Chebyshev Interpolation for image resizing
Donatella Occorsio, Giuliana Ramella, Woula Themistoclakis
Image resizing is a basic tool in image processing and in literature we have many methods, based on different approaches, which are often specialized in only upscaling or downscali…
Image scaling by de la Vallée-Poussin filtered interpolation
Donatella Occorsio, Giuliana Ramella, Woula Themistoclakis
We present a new image scaling method both for downscaling and upscaling, running with any scale factor or desired size. The resized image is achieved by sampling a bivariate polyn…
Evaluation of quality measures for color quantization
Giuliana Ramella
Visual quality evaluation is one of the challenging basic problems in image processing. It also plays a central role in the shaping, implementation, optimization, and testing of ma…
Saliency-based segmentation of dermoscopic images using color information
Giuliana Ramella
Skin lesion segmentation is one of the crucial steps for an efficient non-invasive computer-aided early diagnosis of melanoma. This paper investigates how color information, beside…
