This paper is an overview to Visual Simultaneous Localization and Mapping (V-SLAM). We discuss the basic definitions in SLAM vision system fields provide a review of state-of-the-art methods utilized for mobile robot’s SLAM. covers topics from methods, sensors, machine algorithms feature extraction matching, Deep Learning (DL) datasets Odometry (VO) Loop Closure (LC) V-SLAM applications. Several matching are simulated show better feature-based techniques.
One of the most important key points in intelligent transportation systems is scene understanding known and unknown surrounding environment to achieve a safe driving for smart mobile robots cars. Semantic segmentation can address perception needs Intelligent Vehicles (IV). There are several deep learning approaches based on Convolutional Neural Network (CNN) semantic segmentation. Most these techniques have been designed pretrained network base loading specific weight file necessary them. In...

The conventional fuzzy c-means (FCM) clustering method can be applied on data, where data features are crisp; however, when the fuzzy, FCM cannot utilized. Recently, some researchers numbers used metric has a crisp value. Since differen ce between two represented by value better than one, in this paper, it is going to extend for symmetric triangular numbers, It will shown that proposed distance expresses much metrics. Then been simulated and various real compared with several new methods....
In this paper we present a novel noise reduction method using Coordinate Logic (CL) filters applied to printed text and handwriting images. CL Filters their associated Operations (CLOs) are widely used in common practical image process applications like removing, magnification, opening, closing, skeletonization, coding, edge detection, feature extraction, fractal modeling. Using coordinate logic increases the efficiency, simplicity more than all programs speed compared morphological filters....
