Time Domain Blind Separation of Nonstationary Convolutively Mixed Signals expressions used for first and second order optimization techniques derived in [1] for the instantaneous BSS case are extended to accommodate the more practical convolutive mixing scenario. Traditionally convolutive BSS problems are solved in the frequency domain [2–4] but this requires additional

Speech and Audio Coding Using Temporal Maskinged upon the existing forward masking psychoacoustic data with an assumption of an approximately 200 ms. The model’s dynamic parameters were derived from this data. The previously developed second model was based upon the principle of an exponential decay following higher energy stimuli, where the ma

Objective Hybrid Image Quality Metric for In-Service Quality Assessmenter, existing image quality metrics such as Peak Signal-to-Noise Ratio (PSNR) are inappropriate for in-service quality monitoring since they require the original image to be available at the receiver. Although PSNR and others are objective metrics, they are not based on human visual perception and ar

Classification of Video Sequences in MPEG Domaination only. The classification serves as the first step of the indexing process of a video scene and its retrieval from a large database in order to partition the database into more manageable sub-units according to the types of scenes, e.g. sport, drama, scenery, news reading. The method is intende

Unequal Two-Fold Turbo Codesorm their conventional symmetric and asymmetric cousins in the waterfall region. This article introduces a simple method that allows two-fold turbo codes to offer bi-level unequal error protection. Also, the application of the unequal error protection to a still image coding technique, i.e. huesatur
