High Frame-Rate Television
The frame and field rates that have been used for television since the 1930s cause problems for motion portrayal, which are increasingly evident on the large, high-resolution television displays that are now common. In this paper we report on a programme of experimental work that successfully demonstrated the advantages of higher frame rate capture and display as a means of improving the qualit...
متن کاملTowards an efficient high quality picture-rate up-converter
Motion estimation algorithms play a key role in picture-rate up-conversion. To realise high quality interpolated images, while keeping the processing requirements low, we analyse the following parameters of the motion estimation algorithm: The number of motion estimation iterations per input image pair and the image scanning order of individual iterations. Furthermore, we tackle the issue of th...
متن کاملHigh Frame Rate Egomotion Estimation
In this paper, we present an algorithm for doing high frame rate egomotion estimation. We achieve this by using a basis flow model, along with a novel inference algorithm, that uses spatio-temporal gradients, foregoing the computation of the slow and noisy optical flow. The inherent linearity in our model allows us to achieve fine grained parallelism. We demonstrate this by running our algorith...
متن کاملMeasuring picture quality in compressed systems
A method of estimating the picture quality of an MPEG-2 bitstream without requiring reference to the source picture is presented. The method uses information readily available from the early stages of decoding the bitstream. It is therefore highly suited to applications in which it is required to monitor several video channels and provide an automatic warning of possible picture quality problem...
متن کاملLow-Bitrate Video Quality Enhancement by Frame Rate Up-Conversion and Adaptive Frame Encoding
Frame rate up-conversion (FRUC) is a useful technique for a lot of practical applications, such as display format conversion, low bitrate video coding and slow motion playback. Unlike traditional approaches, such as frame repetition or linear frame interpolation, motion-compensated frame interpolation (MCFI) technique which takes block motion into account is regarded as a more efficient scheme....
