The paper mainly investigates the widely-used image features and related feature selection methods in content-based image retrieval (CBIR).The texture features and shape features that could be used in the retrieval of solar images are mainly discussed. The result of the survey indicates that although the CBIR related research work in solar image retrieval is comparatively less, the existing achievements...
Due to the growing use of mobile video services, monitoring of perceived video quality in live systems becomes of high interest. For this purpose, it is required to capture video quality consistent with the principles behind the operation of the human visual system and to accommodate some suitable quality reference to the transmission of the mobile video service. This can be achieved by extracting...
The growing deployment of mobile video applications is calling for new methods to measure quality as perceived by humans. The suitable quality metrics may explore spatial and temporal video features that quantify the presence of related artifacts in an examined mobile video service. Considering a video as a sequence of images, computation of spatial features for each involved image would pose significant...
