In this paper, the initial work on a fuzzy approach for detecting multi-junctions in edgeness images (points where two or more edges meet) is presented. An 11x11 pixel processing window is divided into overlapping sectors, in which the presence and orientation of line segments is determined by forming the intersection of fuzzy sets, each carrying uncertain information about the orientation of a...

The most common degradations in images is their poor contrast quality. Edge Enhancement is the art of examining images for identifying objects and judging their significance. The proposed paper uses the concept of hybrid edge detection method based on fuzzy sets and cellular learning automata to detect the gray level changes of neighbors of every pixel, and to detect the edge by using the chang...

Path planning is an important aspect and component in the research of mobile-robot-related technologies. Many path algorithms are only applicable to static environments, while practical tasks, uncertainty dynamic environments increases difficulty obstacle avoidance compared with environments. To address this problem, paper proposes RRT*-FDWA algorithm. RRT* first generates a global optimal path...

A Modified Decision Based Unsymmetrical Trimmed Median Filter (MDBUTMF) followed by Fuzzy Noise Reduction Method (FNRM) is proposed for the restoration of color images that are highly corrupted by salt and pepper noise. The proposed filter (MDBUTMF) replaces the noisy pixel by trimmed median value when some of the elements with values 0‟s and 255‟s are present in the selected window. If all the...

Implementing efficient TCP for the Internet necessarily has to cope with the problem that the source does not know in advance which window allocation policy should be the best to use for a given network condition. In this paper, an on-line adaptive fuzzy system is used at the source in an objective to find the best possible weighted combination among the available policies.

In the current Internet, standard TCP congestion control is based on segment loss events possibly assisted by simple explicit router feedback mechanisms like Explicit Congestion Notification (ECN). The performance of TCP congestion control can be improved if a more sophisticated Router Congestion Feedback (RCF) mechanism than ECN is used. One of such approaches is Explicit Window Adaptation (EW...
