Nowadays, digital imaging is mostly based on the paradigm that a combinations of a small number of so-called primary colors is sufficient to represent any visible color. For instance, most cameras use pixels with three dimensions: Red, Green and Blue (RGB). Such lowdimensional technology suffers from several limitations such as a sensitivity to metamerism(More)
Malignant melanoma is the most dangerous type of skin cancer, yet it is the most treatable kind of cancer, conditioned by its early diagnosis which is a challenging task for clinicians and dermatologists. In this regard, CAD systems based on machine learning and image processing techniques are developed to differentiate melanoma lesions from benign and(More)
Different algorithms are available for processing an optical flow field between two successive frames. In most situations, two constraints are necessary to estimate such a displacement vector field. The first constraint is based on the gray level variations. The second one is usually based on the smoothness of the flow field. Unfortunately, the results of(More)
