Něco v Obraze / Something in the Image

Balážová, Anna January 2012 (has links)
The video is an example of motivation, inspiration and record long-term cooperation on the animation, we are creating together with Katarina Hládeková. That cooperation had many stops and mezzanines, for example, when creating a non-existent trailer animation, when creating LOM and Strait installations and at an exhibition Great light first, then a huge blow! At the lecture The bread on both sides of the wind cunning too. It had everything but their predecessor, and has its successor in my Videoscatches sensed that I stack with each other and blend both visually and acoustically in new stories. This video is no animation or image does not pretend to be a film. On the contrary.

Detektory a deskriptory oblastí v obrazu / Region Detectors and Descriptors in Image

Žilka, Filip January 2016 (has links)
This master’s thesis deals with an important part of computer vision field. Main focus of this thesis is on feature detectors and descriptors in an image. Throughout the thesis the simplest feature detectors like Moravec detector will be presented, building up to more complex detectors like MSER or FAST. The purpose of feature descriptors is in a mathematical description of these points. We begin with the oldest ones like SIFT and move on to newest and best performing descriptors like FREAK or ORB. The major objective of the thesis is comparison of presented methods on licence plate localization task.

Metody lokalizace rozdílů v různých modálitách malířských děl / Methods for Localization of Image Differences in Different Modalities of Paintings

Fürbach, Radek January 2013 (has links)
The work focuses on the analysis of paintings to determine the painting techniques. Specifically, it focuses on the localization of the underdrawing by comparing images taken in the spectra with different penetration depth. Defines the problem associated with the capture of the compared images in different spectra. Specifies methods that determine the dependence between two parts of the spectrum (mainly RGB and IR) and based on the dependence approximates conversion between these two parts of the spectrum (Red spectral component projection, Colour intensity, Weighted average of spectral components, Table conversion, Linear regression, PCA analysis and Edge decomposition). Work also describes more general problems that complicate solving tasks, such as noise, non-uniform illumination and adding the same type of radiation. Problems at work are thoroughly analyzed. We design a Calculation of illumination parameters using a neural network, Approximation of illumination by blur, Polynomial approximation of illumination and TWMJ approximation of illumination for suppressing non-uniform illumination. Define methods Estimation by edge decomposition and Local least squares method solving adding the same type of radiation. In addition, we describe the Gaussian filter, the Averaging, Median filter, Conservative...

Algoritmy grafiky a video v GP-GPU / Graphics and Video Algorithms in GP-GPU

Kula, Michal January 2013 (has links)
This diploma thesis is focused on object detections through general-purpose computing on graphics processor units. There is an explanation of graphics adapters work and basics of their architecture in this thesis. Based on the adapters, there is the effective work in libraries for general-purpose computing on graphics processor units demonstrated in this thesis. Further, the thesis shows the available algorithms for object detection and which ones from them are possible to be effectively parallelized. In conclusion of this thesis, there is a comparison of the object detections speeds to common implementations on classical processors.

Rozšířené uživatelské rozhraní / Augmented User Interface

Zahrádka, Jiří January 2011 (has links)
This thesis falls into a field of user interface design. It focuses on tangible user interfaces which utilize a camera and projector to augment physical objects with a digital information. It also includes description of calibration of those devices. The primary object of this thesis is the implementation of an augmented user interface for application windows management. The system consists of a stationary camera, overhead projector and movable tangible objects - boards. The boards are equipped with fiducial markers, in order to be tracked in a camera image. The projector displays the conventional desktop onto the table and the tangible objects. For example, application windows can be projected onto some boards, while the windows move and rotate simultaneously with the boards.

Klient-server mobilní aplikace se zpracováním obrazu / Client-Server Mobile Application with Image Processing

Černošek, Bedřich January 2018 (has links)
The main goal of this work is creating client-server application with image processing and cryptographic verification of image source and creation time. The work focuses on creating a mobile client application on the Android platform that securly takes photos by mobile device camera, processes captured images and provides a digital signature, timestamp and GPS location. The main part of the work is secure key exchange, encrypted communication, data and energy efficiency of the client-server application. The server application is implemented on the Java EE platform and processes the received image, performs object detection, object recognition in the image and provides a timestamp from a trusted server. Then taken photo can be considered as a trusted electronic document usable as valid evidence for the judical or administrative proceedings.

Detekce nánosu UV lepidla / UV adhesive coating detection

Pavelka, Radek January 2018 (has links)
This diploma thesis focuses on a design of camera control system used for detecting defects, appearing during a UV luminescent glue application on the bottom of a paper bag. As a part of this thesis, an application was developed, using Baumer VCXG-53C industrial camera, implementing two dierent control methods - 2D cross correlation image pattern matching based on previously user defined pattern and glue area size measuring based on binary segmented image. The result of this work is a fully developed control system, prepared to be put into operation at the customer’s production line.

Automatizované sledování pohybujících se objektů pomocí robotického manipulátoru / Automated object tracking using robotic manipulator

Zelený, Miroslav January 2021 (has links)
This diploma thesis deals with the tracking of objects using a robotic manipulator Epson C3 and a color camera. The work describes the basic qualities of the device to be used. The OpenCV library and its wrapper EmguCV are used as software tools for computer vision. It discusses the basic issues and principles of tracking objects in the image and introduces some methods of tracking. These methods have been tested and therefore their strengths and weaknesses, which appeared during testing, are listed here. Furthermore, there is a procedure for calculating the new coordinates of the camera and the manipulator effector using homogeneous transformations. The work contains the results of testing the algorithms and their evaluation. The output of the work is a test application for the Epson C3 robot.

Identifikace objektů v obraze / The idnetification of the objects in the imege

Zavalina, Viktoriia January 2014 (has links)
Master´s thesis deals with methods of objects detection in the image. It contains theoretical, practical and experimental parts. Theoretical part describes image representation, the preprocessing image methods, and methods of detection and identification of objects. The practical part contains a description of the created programs and algorithms which were used in the programs. Application was created in MATLAB. The application offers intuitive graphical user interface and three different methods for the detection and identification of objects in an image. The experimental part contains a test results for an implemented program.

Měření výšky postavy v obraze / Height Measurement in Digital Image

Olejár, Adam January 2015 (has links)
The aim of this paper is a summary of the theory necessary for a modification, detection of person and the height calculation of the detected person in the image. These information were then used for implementation of the algoritm. The first half reveals teoretical problems and solutions. Shows the basic methods of image preprocessing and discusses the basic concepts of plane and projective geometry and transformations. Then describes the distortion, that brings into the picture imperfections of optical systems of cameras and the possibilities of removing them. Explains HOG algorithm and the actual method of calculating height of person detected in the image. The second half describes algoritm structure and statistical evaluation.
