The algorithm proposed in this paper integrates the concepts of variable frame rate and discriminative analysis based on Tanimoto ratio to modify the conventional Viterbi algorithm, in such a way that the steady or stationary signal is compressed, while transitional or non-stationary signal is emphasized through the frame-by-frame searching process. The usefulness of each frame is decided entir...

Given a video sequence decompressed from a compressed video sequence associated with motion vector information for each image frame, this short note presents an efficient predictive watershed-based video segmentation algorithm using motion vectors. The proposed algorithm has much computation-saving merit since the next frame can inherit the segmented results of the current frame according to th...

A novel rate-control algorithm with a variable-encoding frame-rate method is proposed in this work for low-bit-rate video coding. Most existing rate-control algorithms for low-bit-rate video focus on bit allocation at the macroblock level under a constant frame-rate assumption. The proposed rate-control algorithm is able to adjust the encoding frame rate at the expense of tolerable time-delay. ...

A novel rate control algorithm consisting of two major components , i.e. a variable encoding frame rate method and a hybrid DCT/wavelet I-frame coding scheme, is proposed in this work for low bit rate video coding. Most existing rate control algorithms for low bit rate video focus on bit allocation at the macroblock level under a constant frame rate assumption. The proposed rate control algorit...

The accuracy of formant frequency estimation on voiced speech in frame-based linear predictive analysis is affected by the position of the analysis frame relative to the instant of onset of vocal tract excitation. An automatic waveform-dependent point-wise analysis which employs a weighted least-square lattice (WLSL) algorithm to minimise these errors is described here. Experiments on both synt...

This paper presents a new direct maximum power point tracking (MPPT) with reference voltage (Vref) based on the metaheuristic earthquake algorithm (EA) where optimization variable is Vref for hard-switching converters. The efficiency and performance of EA-MPPT-Vref compared perturb-and-observe (P&O) counterpart technique due to fact that it widely used commercial products. Static dynamic re...

According to investigating impact of complexity of stereoscopic frame pairs on stereoscopic video coding and transmission, a new rate control algorithm is presented. The proposed rate control algorithm is performed on three levels: stereoscopic group of pictures (SGOP) level, stereoscopic frame (SFrame) level and frame level. A temporal-spatial frame complexity model is firstly established, in ...
