چکیده
In this contribution, we investigate the alternative of performing the wavelet decomposition in the spatial direction before the temporal filtering step for open-loop motion-compensated temporal-filtering (MCTF) systems. In order to efficiently perform the temporal decomposition in the produced spatial wavelet representation of the input frames, we utilize the framework presented in a previous contribution [1], which involves wavelet-domain (in-band) motion estimation and compensation (ME/MC). Additionally, in order to evaluate the trade-offs between the in-band MCTF (IBMCTF) and the conventional spatialdomain MCTF (SDMCTF) systems, we utilize the framework of unconstraint MCTF (UMCTF) proposed in [2]. In the UMCTF framework, by allowing temporal decompositions without the update lifting step, one can attain a set of undistorted frames for the lower temporal resolutions, thereby allowing PSNR comparisons between the different alternatives. This gives a framework for objective assesment of the performance of the two solutions for all the degrees of freedom for scalability, i.e temporal, spatial and SNR.

This document was written based on “very first draft” of MPEG-7 PPD (document N1923), and on some of the discussions in Fribourg and in the AHG. However, it is a personal contribution. For time reasons, we did not include the modifications to N1923 presented by Ibrahim Sezan, which synchronize it to other input documents. Modifications vs. N1923 are indicated through the Word versioning mechani...

The Moving Picture’s Experts Group (MPEG) has recently started work on a new standardization effort called the "Multimedia Content Description Interface," also known as MPEG-7. The goal of MPEG-7 is to enable fast and efficient searching and filtering of audio-visual material. The effort is being driven by specific requirements gleaned from a large number of applications related to image, video...
