Implementation of presence detection with Haar cascade and local binary patterns histograms

School truancy is a significant problem that affects the educational environment and student achievement.  This article presents a project to develop an automated absence detection system for classrooms using Haar Cascade and Local Binary Patterns Histogram (LBHP) techniques.  The study begins by collecting a large dataset of classroom images, including various lighting scenarios and conditions.  Haar Cascade is used to detect human faces in images, followed by LBHP feature extraction for each detected face.  Experimental results demonstrate the effectiveness of the pro

Information System for Adapting Road Lane Segmentation Methods in Navigation Systems in Order to Increase the Accuracy of Road Signs Detection

In today’s world, where the speed of technological change is extremely impressive, the traffic industry is not left behind. The use of lane segmentation on the road is becoming a key element not only for safety, but also for improving navigation and traffic sign detection systems. This approach opens the door to a new level of efficiency and accuracy in traffic management, helping to improve the quality and safety of our movement. Let’s dive into the details of this exciting and promising area of road transport technology development.

Development of an Algorithm and Software System for Facing Panels Accounting on Production Lines

This paper aims to develop and implement an algorithm and an automated software system for the auto- matic accounting process of external facing panels during transportation on line conveyors. The method described in this paper is designed to simplify the process of production and accounting of wall-facing panels. This method can also serve as a model for implementing other manufacturers. The developed  algorithm consists of the following steps: obtaining a video stream in real-time or from a file and its targeted processing and determining the number of moving objects of interest.

Extraction of ideogram features for diagnosing chromosomal abnormalities

This paper proposes an approach to the detection and extraction of specific features in an ideogram image. Ideogram is a depiction of a healthy chromosome used in a karyotyping process - a procedure designed to diagnose chromosomal abnormalities.

Extraction of ideogram features is a part of a general algorithm for the detection of chromosomal abnormlities. According to the general algorithm, both chromosomes and ideograms have to be parsed and converted into a single data format for further comparison.

Development of a Video Surveillance System for Motion Detection and Object Recognition

This article explores the development of a video surveillance system that utilizes cuttingedge technology to analyze the video stream in real-time, identify motion, and recognize objects within the video stream. The functionality of this system enables it to provide a high level of accuracy in identifying objects, even in low-light conditions or with low-resolution cameras. The software system has been designed as a user-friendly desktop application with the latest technologies and features that will ensure its relevance and easy maintenance in the future.

COMPUTER VISUAL INSPECTION OF PEAR QUALITY

A brief description of the basic stages of image processing is given to pay attention to the segmentation stage as a
possible way to improve efficiency in decision-making. The main characteristics of the presented model are visual signs, such as
color, shape, the presence of a stem, and others. Due to the different approaches in image processing, a high level of truthfulness is
achieved, which is expressed in the percentage ratio of the accuracy of decision-making and varies in the range from 90 to 96%.

Comprehensive Analysis of Few-shot Image Classification Method Using Triplet Loss

Image classification task is a very  important problem of a computer vision area. The first approaches to image classification tasks belong to a classic straightforward algorithm. Despite the successful applications of such algorithms a lot of image classification tasks had not been solved until machine learning approaches were involved in a computer vision area. An early successful result of machine learning applications helps researchers with extracted features classification which was not available without machine learning models.

Software Implementation of the Algorithm for Recognizing Protective Elements on The Face

The quarantine restrictions introduced during COVID-19 are necessary to minimize the spread of coronavirus disease. These measures include a fixed number of people in the room, social distance, wearing protective equipment. These restrictions are achieved by the work of technological control workers and the police. However, people are not ideal creatures, quite often the human factor makes its adjustments.

Automation of the measurement procedure in the mechanical north-seeking gyroscop

The aim of the work is to develop an automated measuring system in a mechanical gyrocompass with the help of specially developed hardware and software in order to facilitate the operation of the device and minimize observer errors. The developed complex provides automation only for the time method, as for the method of the turning point it is necessary to constantly contact the motion screw of the total station. The project is based on an integrated system, the hardware part of which contains a single-board computer, camera, and lens.
