From an Optics point of view, small lenses with large apertures are challenging to design. • Lens Focal Length: The focal length and the sensor's physical dimensions define the field of view of the camera  ...  Also, the algorithm has shown to be sensitive to inaccurate estimates for the field of view, and barrel-distortion from the camera lens.  ...

We extensively evaluated this new diusion model and compared with standard ICM in addressing one fundamental algorithmic problem related to viral marketing: How to select a set of network nodes/individuals  ...  However, with the unprecedented ease and low cost of communication provided by online systems, information overload emerges as a negative factor that potentially threatens the eectiveness of communication  ...  Given the known probabilistic parameters, an expected number of total inuenced users can be estimated, and the IM problem concerns whether the current targets can maximize this number.  ...
