State University of telecommunication n.a. prof. М.А. Bonch-Bruevich Color compression in video registration and security systems Department of engineering and computer graphics Phd work Nikolai S. Kazantsev Professor: Vladimir M. Degtyrev
Slide №1 Index • 1. Current state in video registration systems • Problems in usage in east-european market- 2 • neuralmethod of face pattern recognition - 4 • Compression with losses. Why? Ways of traffic reduction- 5,6 • 2. Functional descriptionof the recommended solution • Image division on two colours - 5 • Colour analysis. Defining settings for allocation - 6 • Application of an algorythm on test image - 9 • Application of video system on Russian market - 11 • 3. Summary
Slide №2 Video registration system. Problems in usage in east-european market Security monitors Videocameras Videoregistrator Monitor 1 Monitor 2 Face recognition Operation from computer Alarm sensor Operation from remote control Fig 1. Schema of typical video registration system
Slide №3 Neuro-networkmethodof pattern recognition Fig.2 set of control points Fig. 3. Multilayer neural Network for face recognition.
Slide №4 Widely used methods of compression with loses Fig. 4. Sample of application of JPEG and JPEG2000 algorythmes for image processing.
Slide №5 Ways of traffic reduction • Increase the bandwidth of communication channels and capacity of HDD ( => $, time) • Decrease the image quality (=> efficiency of recognitions goes down) • Decrease the frames pro second number(=> increased chance not to catch a trespasser) Solution?
Slide №6 Loss-free Color Compression 1 2 3 Fig 5. Test image: «Playing soccer»
Slide №7 Colour analysis of image “pure” colours– colours, which brightness can be displayed using 256 bit levels of BitMap file
Slide №8 Graphical modeling
Slide №9 Application of the intellectual color compression method for processing the videostream’s frame Fig 6. demonstration of colour compression.
Slide №10 The structure of experimental registration system Security monitors Videocameras Videoregistrator Monitor 1 Intellectual Color Compression Module Monitor 2 Face detection Operation from computer Alarm sensor Operation from remote control Image 2. Schema of new experimental video registration system
слайд 11 Application of video system on Russian market Now • Loss-free compression fills the communication channels and HDD of video registration with useless information(that won’t be used by future recognition.) • Or compression without intellectual colour detection is used. That is harmful fiorrecognizationbvecause the graph on the fave changes every time. • Future projects are looking for new solutions of the same problem Implementing the developed software. Optimisation of software of VRSystems will let increasing the speed if transfer, increase the number of frames/per second and eventually the quantity of recognized face. Рис. 6.
