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 severly damaged media.
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 with various qualitative aspects in imaging systems. The first part is devoted to the modeling of HVS and image quality evaluation. A model for prediction...
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 tested the impact of image sharpening algorithms on the display readability in presence of noise. The trade-off between the edge-enhancing and noise treatment...
