Smartphone Game Using Recognition of Face Features
Skoták, Jiří ; Szőke, Igor (referee) ; Herout, Adam (advisor)
This master's thesis focuses on smartphone game for iOS, which uses recognition of face features and other information, which can be obtained from a smartphone's camera and sensors. This work describes a few approaches for real-time face detection and then introduces and compares possibilities for such task on iOS. Moreover, the thesis contains a draft of the final game and its levels. The game showcases various technologies in its levels such as object detection, processing an image color and others. Finally, the thesis introduces the final form of the game that is released and available on the App Store.
Music Volume Adjustment Based on Distance Detection
Serečunová, Stanislava
The work is focused on user distance calculation from camera in real time by means of evaluating parameters of detected face. According to the distance of user from the camera sound level is adjusted, so the user can perceive the music on the same level. KLT method is chosen for the detection of face.
Determining Head Rotation in Video from Security Camera
Blucha, Ondřej ; Drahanský, Martin (referee) ; Goldmann, Tomáš (advisor)
This thesis attempts to create an application to determine head rotation angle in video recorded from a security camera. The application consists of three parts: face detection, facial landmarks detection and determination of person's head rotation. The face detection has been implemented using Viola-Jones and HOG algorithms. Facial landmarks detection has been done using algorithm based on active shape model. Two methods to calculate the head rotation angles have been used: the first method works with anthropometric head features. The second method uses Perspective-n-Point algorithm to find the right rotation angles. Finally, all algorithms implemented have been tested and the proper parameters have been determined.
Mobile application for automatic face detection and recognition
Stejskalová, Kristina ; Kolář, Radim (referee) ; Hesko, Branislav (advisor)
This bachelor thesis aims to implement face detection and face recognition method in Java and creating an Android application for face detection and recognition. Methods generally used for face detection and recognition are described in theoretical part. Chosen methods for face detection and face recognition are implemented and then used for building mobile application.
Music volume adjustment based on distance detection
Serečunová, Stanislava ; Koťová, Markéta (referee) ; Janoušek, Oto (advisor)
This work is about two methods of face detection in video sequencing. According to testing the KLT method is chosen. The work is focused on user distance calculation from camera in real time by means of evaluating parametres of detected face. According the distance of user from camera sound regulation is set, so the user can percieve and feel the music on the same level.
Detection of Landscape in Images
Dufka, Zbyněk ; Křupka, Aleš (referee) ; Číka, Petr (advisor)
The target of this thesis is theoretical summary of methods, which are used for detection of objects in database of images. Next step is to develope own algorhytm for detection of landscape. Theoretical part describes methods Viola-Jones and HOG, which are used for detection of human faces and anomalies on radiographs. This analysis is concerned with segmentation method and algorhytm for data mining from images, which contain the landscape scenery. Appropriate method and its analysis could contribute to create and to implement into developement enviroment RapidMiner in the second part of thesis.
Detection of groups of people in images
Mikulčík, Ondřej ; Zukal, Martin (referee) ; Číka, Petr (advisor)
This work describes two methods for detecting objects in images. The first method is the Viola-Jones, the second is the method of histograms oriented gradients. Start of work deals with the theoretical description of the methods. In the other parts of this work is presented creation of the training databases, implementation methods in the RapidMiner and their testing. In conclusion, the results and the use of methods for detection of groups of people in the database of images are evaluated.
Application of facial biometric data in recognition of persons
Bazala, Lukáš ; Přinosil, Jiří (referee) ; Burget, Radim (advisor)
he work deals with themes of detection and identification of human faces in an image. Described are the different biometric methods and work with biometric systems. Further, a problem of image processing is described and proposed a method for locating faces in an image and implementation of Viola-Jones detector in identifying key points in the face
Face recognition
Maňkoš, Richard ; Mézl, Martin (referee) ; Kolář, Radim (advisor)
This diploma thesis deals with face recognition in digital pictures. The first part describes biometry and, shortly, characterizes biometrical methods which are the most oftenly used. In the second part is described the approach of face recognition in a picture. Specifically, it is described the method for face detection - Viola-Jones and method for face recognition - PCA, which will be implemented in Matlab. The last part, which is practical, describes the scheme for video-sequence recording, implementation of the PCA method in Matlab and discussion of the achieved results.
Computer Application Control by Natural Head Movement
Vojvoda, Jakub ; Materna, Zdeněk (referee) ; Beran, Vítězslav (advisor)
The aim of this work is to design and implement a system that tracks user's head in the input video frames and on the basis of its position achieves interaction with computer applications. Four methods for head detection have been proposed based on computer vision techniques as face detection by Haar-like features, background detection, Camshift or Lucas-Kanade to calculate an optical flow. The individual methods have been tested on recorded and in this field used data sets, and evaluated. The implementation of the system was then used to build the demo applications.
