Localization and mapping are fundamental challenges in robotics and computer vision, enabling autonomous systems to understand their environment and navigate within it[1]. One of the most prominent approaches to tackle this problem is Simultaneous Localization and Mapping (SLAM), which allows a robot or device to construct a map of an unknown environment while simultaneously tracking its own position[1][2]. SLAM algorithms typically use sensor data from cameras, LiDAR, or other sensors to build a representation of the environment. Visual SLAM, which relies on camera input, has gained significant attention due to the widespread availability of cameras in mobile devices and robots[2].…

Optical Character Recognition (OCR) is a technology that converts different types of documents, such as scanned paper documents, PDFs, or images captured by a digital camera, into editable and searchable data. It is widely used to digitize printed texts so that they can be electronically edited, searched, stored more compactly, and used in machine processes like cognitive computing and text mining. How OCR Works OCR technology typically involves several steps: Image Acquisition: The document is scanned using an optical scanner, converting it into a digital image. Preprocessing: The image is processed to improve its quality. This involves techniques like noise…
