This document discusses visual pattern recognition in robotics. It describes a system that uses a camera to capture images of traffic sign boards. It then performs three main steps: 1) color-based filtering to isolate the sign board, 2) locating the sign board in the image, and 3) detecting and recognizing the pattern inside the sign board. This allows the robot to understand the sign and move accordingly. The document provides details of the methodology, including image acquisition with MATLAB, image processing steps to analyze the image and extract the sign board, and using the pattern recognition results to control the robot's movement.
This document summarizes a research paper on visual pattern recognition in robotics. It discusses:
1) The paper presents a real-time visual pattern recognition algorithm to detect and recognize traffic signboards using color filtering, locating signs in images, and detecting patterns. Color filtering is the most challenging step.
2) The standard technique involves color segmentation, shape detection using templates, and specific sign detection. The presented algorithm applies a color filter to mark signboard borders, aiming to minimize detecting non-sign red colors.
3) Detection and recognition are the major steps - detection locates signs, and recognition identifies patterns to control the robot's movement accordingly.
Real-time image processing refers to processing digital images continuously with predictable response times. It involves several sub-categories like compression, enhancement, filtering, distortion, display, and coloring. Real-time image processing has applications in security like traffic violation detection and license plate reading. It allows for immediate results, automation of business processes, elimination of user errors, and is generally a fast process. However, it can cause errors when multiple people work on the same code and infrared cameras may have low pixel capabilities affecting object identification.

IRJET- Proposed Approach for Layout & Handwritten Character Recognization in OCRIRJET Journal
This document proposes an approach for layout analysis and handwritten character recognition in optical character recognition systems. It discusses challenges in recognizing text in documents containing both printed and handwritten text, as well as non-text elements like images. The proposed approach uses document segmentation techniques like connected component analysis and block segmentation to separate text and non-text regions, and further separates printed and handwritten text regions. It aims to apply these techniques to handwritten bills to allow segmentation and analysis of the bills in a user-friendly way for small business owners. The key steps involve preprocessing, text/non-text segmentation, layer separation for printed/handwritten text, and block segmentation using a run-length smearing algorithm and white space detection.

It involves four main parts: 1) Designing the OCR toolbox which includes template creation and letter detection. 2) Checking if the number plate has single or double layers. 3) Applying a detection of vehicle number (DVN) algorithm to process the image and recognize characters. 4) Creating a database in Excel to store the vehicle registration details retrieved from OCR and allowing lookup of owner information. The proposed method achieved 96% accuracy on 50 tested number plates. It can potentially help applications like automatic toll collection and traffic monitoring.
Color based image processing , tracking and automation using matlabKamal Pradhan
Image processing is a form of signal processing in which the input is an image, such as a photograph or video frame. The output of image processing may be either an image or, a set of characteristics or parameters related to the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it. This project aims at processing the real time images captured by a Webcam for motion detection and Color Recognition and system automation using MATLAB programming.
In color based image processing we work with colors instead of object. Color provides powerful information for object recognition. A simple and effective recognition scheme is to represent and match images on the basis of color histograms.
Tracking refers to detection of the path of the color once the color based processing is done the color becomes the object to be tracked this can be very helpful in security purposes.
Automation refers to an automated system is any system that does not require human intervention. In this project I’ve automated the mouse that work with our gesture and do the desired tasks.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

APPLICATIONS OF MACHINE VISION

Applications of Machine Vision
Remigiusz Labudzki, Stanislaw Legutko
Abstract
Machine vision (system vision) it's a apply computer vision in industry. While computer vision is focused mainly on
image processing at the level of hardware, machine vision most often requires the use of additional hardware I/O
(input/output) and computer networks to transmit information generated by the other process components, such as a robot
arm. Machine vision is a subcategory of engineering machinery, dealing with issues of information technology, optics,
mechanics and industrial automation. One of the most common applications of machine vision is inspection of the products
such as microprocessors, cars, food and pharmaceuticals. Machine vision systems are used increasingly to solve problems of
industrial inspection, allowing for complete automation of the inspection process and to increase its accuracy and efficiency.
As is the case for inspection of products on the production line, made by people, so in case of application for that purpose
machine vision systems are used digital cameras, smart cameras and image processing software. This paper presents the
possible applications of machine vision in the present.
Keywords: machine vision, image processing, inspection
1 Introduction
The introduction of the automation has revolutionized
the manufacturing in which complex operations have been
broken down into simple step-by-step instruction that can be
repeated by a machine. In such a mechanism, the need for
the systematic assembly and inspection have been realized
in different manufacturing processes. These tasks have been
usually done by the human workers, but these types of
deficiencies have made a machine vision system more
attractive. Expectation from a visual system is to perform
the following operations: the image acquisition and
analysis, the recognition of certain features or objects
within that image, and the exploitation and imposition of
environmental constraints.
Scene constraint is the first consideration for the
machine vision system. The hardware for this sub-system
consists of the light source for the active imaging, and
required optical systems. Different lighting techniques such
as the structured lighting can be used for such purpose. The
process of vision system starts with the image acquiring in
which representation of the image data, image sensing and
digitization is accomplished. Image sensing is the next step
in order to obtain a proper image from the illuminated
scene. Digitization is the next process in which image
capturing and image display are accomplished. The last step
in this process is the image processing in which a more
suitable image is prepared [1]. The first aim of this article is
to show typical examples of the visions systems in the
automated manufacturing systems.
2 Operation of a machine vision system
A visual system can perform the following functions:
the image acquisition and analysis, the recognition of an
object or objects within an object groups. The light from a
source illuminates the scene and an optical image is
generated by image sensors. Image acquisition is a process
whereby a photo detector is used to generate and optical
image that can be converted into a digital image. This
process involves the image sensing, representation of image
data, and digitization. Image processing is a process to
modify and prepare the pixel values of a digital image to
produce a more suitable form for subsequent operations.
Pattern classification refers to the process in which an un-
known object within an image is identified as being part
of one particular group among a number of possible object
groups [1].
3 The components of machine vision
system
A typical machine vision system consists of several
components of the following:
• one or more digital or analogue camera (black and white
or colour) with optical lenses,
• interface the camera to digitize the image (the so-called
frame grabber),
• processor (this is usually PC or embedded processor such
as DSP),
(In some cases, all the elements listed above are included
in the one device, the so-called smart cameras).
• device I/O (input/output), or communication links (e.g.
RS-232) used to report the results of system,
• lens for taking close-ups,
• adapted to the system, specialized light source (such as
LEDs, fluorescent lamps, halogen lamps, etc.),
• software to the imaging and detection of features in
common image (image processing algorithm) (fig. 2),
• sync-sensor to detect objects (this is usually an optical or
magnetic sensor), which gives the signal for the sampling
and processing of image,
• the regulations to remove or reject products with defects.

2. 28
Fig. 2 The latest software Easy Builder (Cognex) for total
analysis of image
The image from the camera is captured by frame
grabber, which is a digitalize device (included in each intel-
ligent camera or located in a separate tab on the computer)
and convert image from a digital camera to digital format
(usually up to two-dimensional array whose elements refer
to the individual image pixels). The image in digital form is
saved to computer memory, for its subsequent processing
by the machine vision software.
Depending on the software algorithm, typically executed
several stages, making up the complete image processing.
Often at the beginning of this process, the image is noise
filtering and colours are converted from the shades of gray
on a simple combination of two colours: white and black
(binarization process). The next stages of image processing
are counting, measuring and/or identity of objects, their
size, defects, or other characteristics. In the final stage of
the process, the software generates information about the
condition of the product inspected, according to prepro-
grammed criteria. When does a negative test (the product
does not meet the established requirements), the program
gives a signal to reject the product, the system may
eventually stop the production line and send information
about this incident to the staff.
4 Application of machine vision
Machine vision systems are widely used in the manu-
facture of semiconductors, where these systems are carrying
out an inspection of silicon wafers, microchips, components
such as resistors, capacitors and lead frames [3].
In the automotive machine vision systems are used in
control systems for industrial robots, inspection of painted
surfaces, welding quality control [4, 5], rapid-prototyping
[6, 7], checking the engine block [8] or detect defects of
various components. Checking products and quality control
procedures may include the following: the presence of parts
(screws, cables, suspension), regularity of assembly, of the
proper execution and location of holes and shapes (curves
[9], circular area [10], perpendicular surfaces, etc.), correct
selection of equipment options for the implementation of
the quality of surface markings (manufacturer's numbers
and geographical detail), geometrical dimensions (with an
accuracy of a single micron) [2, 11, 12,] the quality of
printing (location and colour).
Beside listed above are other area to implement machine
vision. Figure 3 shows the simplest arrangement of the
machine vision measuring olive oil bottles on production
lines. The online defect inspection method based on machine
vision for float glass fabrication is shown in Fig. 4. This
method realizes the defect detection exactly and settles the
problem of miss-detection under scurvinesss fabricating cir-
cumstance. Several digital line-scan monochrome cameras
are laid above float glass to capture the glass image. The red
LED light source laid under the glass provides illumination
for grabbing the image. High performance computers are
used to complete the inspection task based on image process-
sing [14].
Fig. 3 The simplest arrangement of the machine vision
measuring olive oil bottles on production lines [13]
Fig. 4 Float glass inspection system [14]
Fig. 5 System configuration for validation testing of vehicle
instrument cluster [15]
Another interesting proposition is use the machine vision
system to validation of vehicle instrument cluster [15]. The
machine vision system (Fig. 5) consists of a camera, ligh-
ting, optics and image processing software. A Cognex In-
sight CCD vision sensor was selected for image acquisition
and processing, which offers a resolution of 1600 x 1200
pixels and 64 MB flash memory. The acquisition rate of the
vision sensor is 15 full frames per second. The image
acquisition is through progressive scanning. The camera can
work in a partial image acquisition mode, which provides
flexibility for selecting image resolution and acquisition
rate. The image processing software provides a wide library
of vision tools for feature identification, verification, mea-
surement and testing applications. The PatMaxTM
tech-
nology for part fixturing and advanced OCR/OCV tools for
reading texts are available within the software. The primary
source of illumination is from LED ring lights with direc-
3. 29
tional front lighting, which provides high contrast between
the object and background. The selection of optical lens
depends on the field of view and the working distance. In
this setting, a lens with a focal length of 12 mm is used.
5 Conclusions
In the design and operation of a vision system, the image
formation and visual process, computational methods and
algorithms, depth information, image representation, and
modeling and matching must be considered. On the other
hand, the systematic consideration is important in the effi-
ciency and the performance of the selected machine. The
integration possibility, robustness, ease of operation, and
adding intelligence into the system in order to make it a
smart system are features of the advanced machine vision
systems. Application of machine vision is different and
wide, they are such:
– biometrics,
– positioning [16, 17],
– industrial production on a large scale,
– small-lot production of unique objects [18],
– safety systems in industrial environments,
– intermediate inspection (e.g. quality control),
– visual control of inventory in the warehouse and mana-
gement systems (counting, reading bar codes, storage
interfaces for digital systems),
– control of autonomous mobile robots [19],
– quality control and purity of food products,
– exploitation of bridges [20],
– retail automation [21],
– agriculture [22],
– exploitation of railways [23],
– vision systems for blind people.
