In path planning, potential fields introduce force constraints to ensure curvature continuity of trajectories and thus to facilitate path-tracking design. In previous works, a path planning design by fractional (or generalized) repulsive potential has been developed to avoid fixed obstacles: danger level of each obstacle was characterized by the fractional(More)
Numerous anatomical studies of the human brain have shown a significant inter-individual variability of brain characteristics. Specifically, the extracted characteristics are used in our application as a biometric tool to identify individuals. For this purpose, Magnetic Resonance Imaging (MRI) images are considered. We show that using a single slice from an(More)
In this paper, we aim to classify remotely sensed images for land characterisation. The major goal is approaching the natural nonlinear mixture for band observation and then dimension reduction by supervised classification. After that, an unsupervised method combining feature extraction and SVM in investigating to discriminate the land cover for SPOT 4(More)
Intravascular Ultrasound (IVUS) images are usually corrupted by different types of noises in the process of receiving, coding and transmission. Speckle noise is an inherent property of such images; it causes considerable degradation in the image quality, and thereby reducing the diagnostic value of this wide medical imaging procedure. Accordingly, the(More)
Speckle noise is an inherent property of intravascular ultrasound imaging (IVUS) and it generally tends to deteriorate the image quality, thereby reducing the diagnostic value of this medical imaging modality. As a result, the speckle reduction filtering is considered to be an important and essential procedure to be used, whenever IVUS images are used for(More)
