The key tenet of this research is that most visual analysis tasks can be carried out based on a succinct representation of the image, which entails both global and local features, while it disregards the ...
Specifically, GreenEyes will pursue the following goals: i) energy-constrained extraction of visual features; ii) rate-efficiency modelling and coding of visual feature; iii) networking streams of visual ...
However, it is partially at odds with the paradigm adopted by the human visual system: first, image analysis is often based on a compressed and hence lossy representation of the original image, which might ...

Despite the great efficiency and low storage requirements for our method, we produce results of comparable quality to state-of-the-art methods for content-aware image and video resizing. ...
These shrinkability maps are highly compressible, so the resulting multi-sized videos are typically less than three times the size of the original compressed video. ...
Our cumulative shrinkability maps, after lossy compression, are even smaller than the compressed input video, and the error caused by lossy compression has negligible affect on the output resized result ...
