Automatic Segmentation of Color Lip Images Based on Morphological Filter
This paper addresses the problem of lip segmentation in color space, which is a crucial issue to the success of a lip-reading system. We present a new segmentation approach to lip ...

Improving NDVI Time Series Class Separation using an Extended Kalman Filter
It is proposed that the NDVI time series derived from MODIS multitemporal remote sensing data can be modelled as a triply (mean, phase and amplitude) modulated cosine function. A ...

Arithmetic Transformations to Maximise the Use of Compressor Trees
Complex arithmetic computations, especially if derived from bit-level software descriptions, can be very inefficient if implemented directly in hardware (e.g., by translation of t...
