In this article we present the results of tests we did on MPEG-2 and H.264 codecs in order to measure their error resilience.The data flow is being tested in its raw unprotected form which simulates reception of DVB-T in very bad conditions or severl

The image and video sensing and processing systems are of high importance nowadays. The crucial parameter is image quality as a part of QoS or more recently QoE (Quality of Experience) as a subjective impact (perception). This invited paper deals wit

The paper deals with elimination of defocusing and thermal noise out of black & white pictures captured by a CCD/CMOS camera with imperfectly adjusted lens. For purposes of image recovery we can use the MAP criterion based iterative detection network

During last several years we have studied selected techniques for quality enhancement of security images. The first part of paper demonstrates selected results of image enhancement oriented to the improvement of identification threshold. We have test
