Encoding mode selection in HEVC with the use of noise reduction

Abstract: This paper concerns optimization of encoding in HEVC. A novel method is proposed in which encoding modes, e.g. coding block structure, prediction types and motion vectors, are selected basing on noise-reduced version of the input sequence, while the content, e.g. transform coefficients, are coded basing on the unaltered input sequence. Although the proposed scheme involves encoding of two versions of the input sequence, the proposed realization ensures that the complexity is only negligibly larger than complexity of a single encoder. The proposal has been implemented and assessed. The experimental results show that the proposal provides up to 1.5% bitrate reduction while preserving the same video quality.

Secure transfer of radio specific data

Abstract: The apparatus and method for transferring radio specific data from the memory of an integral logic unit of a radiotelephone to a second, replacement, memory is disclosed. Security of the data is realized by encoding the radio specific data with an operative number generated from a seed number. If the radio specific data is properly transferred to the second memory, the radio specific data is deleted from the memory of the integral logic unit.

The emotion-induced memory trade-off: More than an effect of overt attention?

Abstract: Although it has been suggested that many effects of emotion on memory are attributable to attention, in the present study we addressed the hypothesis that such effects may relate to a number of different factors during encoding or postencoding. One way to look at the effects of emotion on memory is by examining the emotion-induced memory trade-off, whereby enhanced memory for emotional items often comes at the cost of memory for surrounding background information. We present evidence that this trade-off cannot be explained solely by overt attention (measured via eyetracking) directed to the emotional items during encoding. Participants did not devote more overt attention to emotional than to neutral items when those items were selectively remembered (at the expense of their backgrounds). Only when participants were asked to answer true/false questions about the items and the backgrounds—a manipulation designed to affect both overt attention and poststimulus elaboration—was there a reduction in selective emotional item memory due to an increase in background memory. These results indicate that the allocation of overt visual attention during encoding is not sufficient to predict the occurrence of selective item memory for emotional items.

On the general defective channel with informed encoder and capacities of some constrained memories

Abstract: From an information-theoretical point of view the write once memory (WOM), the unidirectional memory (WUM), the write isolated memory (WIM), the memory with address faults (MAF), Blackwell's broadcast channel, and some other constrained memories and channels with an informed encoder can be considered as particular cases of the general defective channel (GDC) introduced by Kuznetsov (1983) as a generalization of a memory with defects. Using the concept of the GDC we consider a unified approach to the investigation of different types of natural and artificial channels with a finite number of states known to the encoder, but unknown to the decoder. To illustrate the usefulness of this approach we derive the capacities of the above-mentioned constrained memories (WOM, WUM, WIM, MAF) as corollaries of lower and upper bounds for the number of messages transmitted over the GDC. >
