But accurate mouth segmentation algorithms may be bound up with high computational cost; it is desirable to consider the algorithm characterized by low computational cost and coarse segmentation, such as returning a simple rectangular or circular window on lip.
For the engineering optimization problems characterized by high computational cost and multiple local optima, the combination use of surrogate model and meta-heuristic algorithm is increasingly popular.
Compared to a comprehensive probabilistic simulation of the life-cycle, the proposed approach is characterized by a computational efficiency increased by several orders of magnitude and by simplicity of implementation.
This tool, based on the joint use of a specialized Koiter asymptotic method and a mixed solid-shell finite element model, is accurate, simple and characterized by a computational cost far lower than standard path-following approaches and many advantages with respect to asymptotic analysis performed with shell elements.
In [17] an MRP transform-expand-sample (TES) is evaluated, which is characterized by higher computational complexity.
The algorithms previously used are characterized by high computational complexity and generally deliver highly accurate disparity maps.
The implementation of efficient baseband receivers characterized by affordable computational load is a crucial point in the development of transmission systems exploiting diversity in different domains.
The design of MCBER-MUD and GA-assisted channel estimation for STBC MC-CDMA is motivated by the basic requirements of implementing an actual receiver scheme (that, therefore, cannot assume the ideal CSI knowledge) characterized by affordable computational load and near-optimal performance.
Proteins that did not show any significant hits in NCBI nr database or showed similarity to unknown or hypothetical proteins were characterized by additional computational tools.
