The Sound Event Detection task aims to determine the temporal locations of acoustic events in audio clips. In recent years, relevance this field is rising due introduction datasets such as Google AudioSet or DESED (Domestic Environment Detection) and competitive evaluations like DCASE Challenge (Detection Classification Acoustic Scenes Events). paper, we analyze performance systems under divers...

Spatial multi-resolution video sequences provide video at multiple frame sizes, allowing extraction of only the resolution or bit rate required by the user. This paper proposes fine-to-coarse motion estimation (ME) for multiresolution video coding. While coarse-to-fine ME, used in previously proposed coding schemes, can provide a better estimate at the coarsest resolution, it is outperformed by...

High-resolution image mosaics construction is one of the significant topics of research in the fields of computer vision, image processing, and computer graphics. Video mosaics contain enormous valuable information but when analyzing, searching or browsing a video, redundancy between frames creates problem. Therefore it is more suitable to bring together all the frames of a shot into one single...

the present research proposes and optimizes the performance of a novel solar-driven combined cooling, heating, and power (cchp) kalina system for two seasons—winter and summer—based on exergy, exergo-economic, and exergo-environmental concepts applying a non-dominated sort genetic algorithm-ii (nsga-ii) technique. three criteria, i.e. daily exergy efficiency, total product cost rate, and total ...
