Color based image processing , tracking and automation using matlab
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.

Computer graphics have many applications including television, newspapers, and medical imaging. Graphics software enables manipulating visual images on a computer and includes programs for animation, modeling, and photo editing.
Characteristics of Display Adapter
An image is a digital representation of a real-world object displayed on a screen. Images consist of a rectangular grid of pixels, which are the smallest individual elements that make up the image. More pixels provide a more accurate representation of the original object or scene. The resolution of an image refers to the number of pixels in the horizontal and vertical dimensions, affecting the clarity and size of the image on screen. Color depth, measured in bits per pixel, determines the number of colors that can be displayed in an image, from 2 colors for 1 bit to over 16 million colors for 24 bits.

OpenGL is a software interface that allows programmers to create 2D and 3D graphics. It consists of over 150 commands to specify graphics objects and operations. OpenGL is designed to be hardware-independent and supported across different platforms. The OpenGL architecture uses a pipeline that processes commands from display lists, evaluates polynomials, performs per-vertex and per-fragment operations, and renders to the framebuffer. Key operations include geometric primitives, attributes, transformations, viewing, clipping, blending, and using a z-buffer for hidden surface removal. OpenGL programs utilize various functions to define graphics, attributes, views, inputs, and window controls.
4 CG_U1_M3_PPT_4 DDA.pptx
This document discusses scan conversion and line drawing algorithms. Scan conversion is the process of representing graphics objects as a collection of pixels. It converts vector images into raster images for display. Common objects that can be scan converted include points, lines, polygons, and characters. The document describes two algorithms for line drawing in scan conversion: DDA (Digital Differential Analyzer) and Bresenham's algorithm. It provides examples of how to use the DDA algorithm to plot lines between points by calculating the change in x and y values at each step and setting pixels accordingly.

Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
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%.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
