Face and texture image analysis with quantized filter response statistics
Author(s) :
Ahonen, Timo
Description :
Abstract
Image appearance descriptors are needed for different computer vision applications dealing with, for example, detection, recognition and classification of objects, textures, humans, etc. Typically, such descriptors should be discriminative to allow for making the distinction between differ...

Face colour under varying illumination - analysis and applications
Author(s) :
Martinkauppi, Birgitta
Description :
Abstract
The colours of objects perceived by a colour camera are dependent on the illumination conditions. For example, when the prevailing illumination condition does not correspond to the one used in the white balancing of the camera, the object colours can change their appearance due to the lack...

Learning and recognizing texture characteristics using local binary patterns
Author(s) :
Turtinen, Markus
Description :
Abstract
Texture plays an important role in numerous computer vision applications. Many methods for describing and analyzing of textured surfaces have been proposed. Variations in the appearance of texture caused by changing illumination and imaging conditions, for example, set high requirements on...

Camera based motion estimation and recognition for human-computer interaction
Author(s) :
Hannuksela, Jari
Description :
Abstract
Communicating with mobile devices has become an unavoidable part of our daily life. Unfortunately, the current user interface designs are mostly taken directly from desktop computers. This has resulted in devices that are sometimes hard to use. Since more processing power and new sensing t...

Object motion estimation using block matching with uncertainty analysis
Author(s) :
Sangi, Pekka
Description :
Abstract
Estimation of 2-D motion is one of the fundamental problems in video processing and computer vision. This thesis addresses two general tasks in estimating projected motions of background and foreground objects in a scene: global motion estimation and motion based segmentation. The work con...

Blur invariant pattern recognition and registration in the Fourier domain
Author(s) :
Ojansivu, Ville
Description :
Abstract
Pattern recognition and registration are integral elements of computer vision, which considers image patterns. This thesis presents novel blur, and combined blur and geometric invariant features for pattern recognition and registration related to images. These global or local features are ...

Vision-based human motion description and recognition
Author(s) :
Kellokumpu, Vili-Petteri
Description :
Abstract
This thesis investigates vision based description and recognition of human movements. Automated vision based human motion analysis is a fundamental technology for creating video based human computer interaction systems. Because of its wide range of potential applications, the topic has bec...
