This document discusses a lane segmentation system for self-driving cars using image processing. The system uses a camera mounted on a vehicle to capture live video frames, which are then processed by a Raspberry Pi computer. Image processing techniques like morphological transformations and Hough line transforms are used to detect lane lines from the frames. The morphological transformations involve operations like erosion and dilation to preprocess the images. Hough transforms represent lines from detected image edges as points in parameter space to effectively identify lane lines. Some challenges of the system include detecting lanes in various lighting and weather conditions. The advantages are that it could help reduce accidents and enable driverless vehicles.

IMPROVEMENTS OF THE ANALYSIS OF HUMAN ACTIVITY USING ACCELERATION RECORD OF E...sipij
The use of Holter Electrocardiograph (Holter ECG) is rapidly spreading. It is a wearableelectrocardiograph that records 24-hour electrocardiograms in a built-in flash memory, making it possibleto detect atrial fibrillation (Atrial Fibrillation, AF) through all-day activities. It is also useful for screeningfor diseases other than atrial fibrillation and for improving health. It is said that more useful informationcan be obtained by combining electrocardiograph with the analysis of physical activity. For that purpose,the Holter electrocardiograph is equipped with heart rate sensor and acceleration sensors. If accelerationdata is analysed, we can estimate activities in daily life, such as getting up, eating, walking, usingtransportation, and sitting. In combination with such activity status, electrocardiographic data can be expected to be more useful.

Gear is a widely used mechanical component whose primary use is to transmit power from one shaft to
other. Gears are of many types namely spur gear, helical gears, worm gears etc. Gear drives are used in various
kinds of machines like automobiles, metal cutting tools, material handling equipment’s, rolling mills, marine
power plants etc. MATLAB is extensively used for scientific & research purposes. It is accurate & also has a
number of built in functions which makes it versatile. Gear Measurement has been carried out by focusing two
features of gear image object. The problems are to measure the gear features of gear image object, in the sense the
measurement of the area of the gear image object and as well the teeth of the gear will be counted. MATLAB tool

image object counted.
DIGITAL RESTORATION OF TORN FILMS USING FILTERING T ECHNIQUESAM Publications
The acceptance of digital imaging is motivating many photography enthusiasts to transfer their
photographic archive to digital form. Scans of negatives and positives are preferred to be scanned at high resolution
which makes small cracks and scratches very apparent. These unsightly defects have become an important issue
for consumers. Filtering techniques are used for the restoration process which is fully automatic whereas the existing
systems were semi-automatic or completely manual. The method used for the detection of tear is dilation process and
top-hat transform. Top-hat transform might misinterpret dark brush strokes as cracks. In order to avoid these
unwanted alterations to the original image, brush strokes are separated from the actual cracks using clustering
technique. Tear removal includes order statistics filtering which deals with the reconstruction of missing or
damaged image areas.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
