What is Edge Detection Edge detection is a collection of mathematical techniques that are aimed at recognizing edges, which are defined as curves in a digital image at which the brightness of the image changes abruptly or, more formally, contains discontinuities. The difficulty of discovering discontinuities in one-dimensional signals is referred to as step detection, and the problem of finding signal discontinuities over time is referred to as change detection. Both of these techniques are used to find discontinuities in signals. The method of edge detection is an essential tool in the fields of image processing, machine vision, and computer vision, notably in the areas of feature detection and feature extraction.

In this book four new methods are proposed. In the first method the generalized type-2 fuzzy logic is combined with the morphological gra-dient technique. The second method combines the general type-2 fuzzy systems (GT2 FSs) and the Sobel operator; in the third approach the me-thodology based on Sobel operator and GT2 FSs is improved to be applied on color images. In the fourth approach, we proposed a novel edge detec-tion method where, a digital image is converted a generalized type-2 fuzzy image. In this book it is also included a comparative study of type-1, inter-val type-2 and generalized type-2 fuzzy systems as tools to enhance edge detection in digital images when used in conjunction with the morphologi-cal gradient and the Sobel operator. The proposed generalized type-2 fuzzy edge detection methods were tested with benchmark images and synthetic images, in a grayscale and color format. Another contribution in this book is that the generalized type-2 fuzzy edge detector method is applied in the preprocessing phase of a face rec-ognition system; where the recognition system is based on a monolithic neural network. The aim of this part of the book is to show the advantage of using a generalized type-2 fuzzy edge detector in pattern recognition applications. The main goal of using generalized type-2 fuzzy logic in edge detec-tion applications is to provide them with the ability to handle uncertainty in processing real world images; otherwise, to demonstrate that a GT2 FS has a better performance than the edge detection methods based on type-1 and type-2 fuzzy logic systems.

Nowadays, integrated land management is generally governed by the principles of sustainability. Land use management usually is grounded in satellite image information. The detection and monitoring of areas of interest in satellite images is a difficult task. We propose a new methodology for the adaptive selection of edge detection algorithms using visual features of satellite images and the multi-criteria decision-making (MCDM) method. It is not trivial to select the most appropriate method for the chosen satellite images as there is no proper algorithm for all cases as it depends on many factors, like acquisition and content of the raster images, visual features of realworld images, and humans’ visual perception. The edge detection algorithms were ranked according to their suitability for the appropriate satellite images using the neutrosophic weighted aggregated sum product assessment (WASPAS) method. The results obtained using the created methodology were verified with results acquired in an alternative way—using the edge detection algorithms for specific images. This methodology facilitates the selection of a proper edge detector for the chosen image content.

What is Canny Edge Detector This edge detection operator is known as the Canny edge detector, and it employs a multi-stage method in order to identify a large variety of edges that are present in images. In 1986, John F. Canny was the one who had the idea for it. Additionally, Canny developed a computational theory of edge detection, which explains the logic behind the effectiveness of the technique.

The first project, leveraging libraries like OpenCV, Pillow, imageio, and Matplotlib, offers a streamlined interface for analyzing RGB histograms from video files. The main window is initialized using the AnalyzeHistogramFrame class, where users interact with buttons, labels, and canvases. Upon loading a video file via the "Open Video" button, the open_video() method utilizes imageio to display the first frame in the GUI canvas. Playback controls such as "Play/Pause" and "Stop" manage the video's playback state, with the show_frame() method continuously updating the displayed frame. Users can engage with the frame by zooming with the mouse wheel or defining a region of interest (ROI) through click-and-drag actions. Upon releasing the mouse button, the analyze_histogram method extracts the ROI, displaying it alongside its RGB histogram in a separate window, courtesy of Matplotlib. The histogram analysis process involves plotting individual RGB channel histograms, combined into a unified histogram. These plots are converted into Tkinter-compatible images for seamless integration into the GUI, empowering users with a comprehensive tool for visualizing and exploring video frame data. The second project is a Python application built with Tkinter, a GUI library, to enable users to analyze RGB histograms of the filtered of cropped image of a certain frame. It combines several libraries like PIL, imageio, OpenCV, NumPy, and Matplotlib to provide a comprehensive interface and analytical capabilities. The application's structure revolves around a class named Filter_CroppedFrame, responsible for managing the GUI and functionalities. Initially, the script imports necessary libraries and defines the Filter_CroppedFrame class. This class initializes the main window, sets up attributes, and creates GUI elements such as buttons, comboboxes, and canvas for video display. Users can load video files using a file dialog, which triggers the open_video() method to load the video via imageio. Playback controls for play, pause, and stop are provided, managed by methods like play_video(), toggle_play_pause(), and stop_video(). The show_frame() method updates the displayed frame based on the playback state and zoom level. Interactive analysis is facilitated through user interactions like zooming and drawing bounding boxes, handled by methods such as on_mousewheel(), on_press(), on_drag(), and on_release(). After drawing a bounding box and releasing the mouse button, the analyze_histogram method is called to extract the cropped region, apply selected filters, and display the cropped image with its RGB histogram in a popup window. The application supports various filters like Gaussian, mean, median, bilateral, and wavelet transforms, applied via the apply_filter() method, with filter selection facilitated by GUI elements like comboboxes. The script concludes with a main function initializing the application by creating an instance of the Filter_CroppedFrame class and starting the main event loop, enabling seamless GUI responsiveness and analysis tasks execution. The third project centers around a GUI application designed to facilitate edge detection within cropped images sourced from video files. Developed using Tkinter, the application boasts an array of interactive elements such as buttons, labels, and comboboxes to enhance user experience and functionality. At its core, the Edges_CroppedFrame class governs the application's operations, initializing critical attributes and orchestrating the creation of graphical components. A key feature of the application lies in its robust handling of video files. Users can effortlessly load video files via a file dialog interface, leveraging the imageio library for efficient frame extraction. The seamless rendering of frames onto a Tkinter canvas forms the foundation of the GUI, allowing users to navigate frames, control video playback, and utilize zoom features through intuitive buttons and comboboxes. Central to the application's functionality is its capability for edge detection within defined regions of interest (ROIs) within frames. Leveraging the OpenCV library, the application seamlessly integrates various edge detection algorithms, including Canny, Sobel, Prewitt, Laplacian, Scharr, FreiChen, Roberts, Kirsch, and Robinson. Users can interactively select rectangular ROIs within frames using mouse-driven actions, with the application dynamically updating the displayed frame to showcase the selected ROI alongside its corresponding histogram. Furthermore, the application extends its utility by enabling concurrent processing of multiple videos. Users can spawn new instances of the application, facilitating comprehensive video analysis and edge detection tasks across different video files. This feature enhances versatility and scalability, catering to diverse user requirements and amplifying the application's utility for advanced video processing endeavors.

Image techniques have been developed and implemented for various purposes, and image engineering (IE) is a rapidly evolving, integrated discipline comprising the study of all the different branches of image techniques, and encompassing mathematics, physics, biology, physiology, psychology, electrical engineering, computer science and automation. Advances in the field are also closely related to the development of telecommunications, biomedical engineering, remote sensing, surveying and mapping, as well as document processing and industrial applications. IE involves three related and partially overlapping groups of image techniques: image processing (IP) (in its narrow sense), image analysis (IA) and image understanding (IU), and the integration of these three groups makes the discipline of image engineering an important part of the modern information era. This is the first handbook on image engineering, and provides a well-structured, comprehensive overview of this new discipline. It also offers detailed information on the various image techniques. It is a valuable reference resource for R&D professional and undergraduate students involved in image-related activities.
