Faces must be present in images for intelligent vision-based human computer interaction to work. Since many years ago, face recognition research has been ongoing and significant. This procedure entails facial tracking, expression recognition, and many other things. It is crucial to first register the positions of the photos in this process. However, maintaining such a database is highly challenging because of pose invariance, illumination invariance, shift invariance, scale and noise invariance. The Image Registration Algorithm will be used to register all of the unknown photos that are currently in the database. With the use of a reference, this registration technique tries to align a pattern image. This algorithm will produce features that are independent of translation, scaling and rotation. High dimension space, which must be decreased using a dimension reduction algorithm, is the primary challenge in face recognition. This low dimension subspace can be produced using dimension reduction methods like as Linear Discriminant Analysis, Principal Component Analysis and Locality Preserving Projection. In order to find the needed image from the given database, this study will first minimize the dimensions of every image that is now there.

This paper focuses on the task of clothing parsing, which is a special case of the more general object segmentation task well known in the field of computervision. Each pixel is to be assigned to one of the clothing categories or background. Due to complexity of the problem and lack of data (until recently) performance of the modern state-of-the-art clothing parsing models expressed in terms of mean Intersection over Union metric (IoU) does not exceed 55%. In this paper, we propose a novel multitask network by extending fully-convolutional neural network U-Net with two side branches - one solves a multilabel classification task and the other predicts bounding boxes of clothing instances. We trained this network using a large-scaled iMaterialist dataset (Visipedia, 2019), which we refined. Compared to well performing segmentation architectures FPN, DeepLabV3, DeepLabV3+ and plain U-Net, our model achieves the best experimental results.

The integration of Traffic Light Detection (TLD) systems with Advanced Emergency Braking Systems (AEBS) marks a critical milestone in enhancing road safety and paving the way for advanced autonomous driving. This survey paper provides a panoramic and extensive overview of the state-of-the-art TLD solutions leveraging sensors and deep learning techniques. With an increasing emphasis on accident prevention and traffic management, the intersection of TLD and AEBS has become a focal point of research and development. This survey begins by elucidating the fundamental challenges associated with TLD, including varying environmental conditions, occlusions, and complex traffic scenarios. We explore the pivotal role of sensors such as cameras, LiDAR, and radar in providing the requisite data for TLD, and delve into the intricacies of sensor fusion techniques for enhanced perception. Deep Learning has emerged as a cornerstone technology in TLD, enabling robust object detection, classification, and real-time decision-making. We meticulously analyze a spectrum of deep learning architectures including Single-Shot Detectors (SSD), Faster R-CNN, YOLO, and custom-designed networks tailored for TLD applications. Furthermore, the survey examines critical components of the TLD pipeline, encompassing data collection, preprocessing, model training, real-time inference, and integration with AEBS. Emphasis is placed on real-time constraints, multi-modal sensor fusion, and adaptability to diverse traffic light configurations. The paper also delves into the significance of accurate traffic light state prediction, going beyond mere detection to anticipate traffic light changes and optimize vehicle control actions. Human-centric interaction and privacy concerns are addressed, encompassing driver warnings, user interfaces, and data anonymization strategies. Moreover, the survey discusses the importance of safety, validation, and collaboration within the TLD and AEBS ecosystem, emphasizing compl

Internet of Thing (IoT) systems using sixth generation (6G) wireless systems, including such haptic feedback, social contact, and expanded realities, have a wide range of requirements for latencies, dependability, bit rate, and consumer performance measures. In terms of managing, run, and optimize the 6Portable wireless network and its core IoT service, it is necessary to create a new structure in order to enable IoT programs over 6G. Digital twins (DT) can serve as the foundation for this type of new 6G infrastructure. The 6G physical system is portrayed virtually by DTs, which also include the techniques, modern communications, computer processing platforms, & confidentiality and safety technicians. The primary design objectives are presented first. Firstly, we outline the essential design specifications for utilizing a DT to enable 6G. Then, design patterns and elements including edge-cloud-based twins, cloud-based twins, and advantage twins are discussed. We also give a comparative description of different twins. Lastly, we present and suggest suggestions for a number of potential future study trajectories.

We integrate smart control and sensing devices into traditional manual watering operations to address issues of the traditional campuses. The campus watering operation is one of the primary goals of future smart campus and Internet of Things (IoT) development. The precision watering system contributes to the university's achievement of the Sustainable Development Goals (SDGs).

In this paper, a robust state feedback controller is presented to track output voltage of boost converter. According to the applications of boost converter in modern industry such as electric cars, solar inverters and DC motor drives, the ability to control output voltage is an important parameter. As the model of boost converter is a nonlinear system, the linear classical controllers may not suffice. In this paper, the model of boost converter is extracted and a simplified state feedback controller is presented which uses Legendre polynomials in order to compensate the eliminated terms. For validation of proposed method, this controller is compared with classical proportional integral controller from the view point of speed and simplicity. The simulation results prove that this controller can not only maintain stability even in occurrence of error in current sensor, but also it can track the reference voltage very fast with no steady state error.

Grape cultivation is vital to the global economy, but various diseases threaten grapevine health and yield. Early and accurate disease detection is crucial for implementing effective control measures. Traditional methods rely on visual inspection by experts, which is subjective and time-consuming. Automated approaches using deep learning offer a promising alternative. The goal of this study was to create a convolutional neural network (CNN) model that can identify grapevine leaf diseases reliably. The aim of the study was to train the model for distinguishing between healthy and infected leaves by three diseases that are common in them such as black rot, esca, and leaf blight. We collected a dataset of images containing healthy and diseased grape leaves. The dataset was pre-processed and augmented to increase data diversity and ensure consistency. The CNN model was developed using TensorFlow and Keras and consisted of convolutional, pooling, dense, and activation layers. Optimizations were implemented using cross-entropy loss function, adam optimizer, and Dropout layers. Model performance was evaluated using metrics such as accuracy of the model, the precision at which it cannot wrongly label a negative sample, the recall at which it can find all the positive outputs, and F1-score which is the ratio between precision and recall. The developed CNN model achieved high accuracy in disease identification. We observed significant accuracy, precision, F1-score, and recall values across all disease categories, demonstrating the model's effectiveness in distinguishing between healthy and diseased leaves. This study successfully demonstrates the potential of CNNs for automated grape leaf disease identification. The developed model offers a promising tool for viticulturists to improve early disease detection and ultimately enhance grape yield and quality. Future research could focus on expanding the model's capabilities to identify a wider range of diseases and exploring its
