All these modalities may be in play simultaneously.
Other imaging modalities may be helpful in understanding the pathogenesis of these fundus lesions.
Besides machine vision, depending on the specific system requirements and the complexity of the task, alternative sensing modalities may be adopted.
During the various stages of user product interactions, different sensory modalities may be important and different emotional responses may be elicited.
Therefore, in cases of clinical uncertainty or where treatment may be modified on the basis of activity versus quiescent disease, additional imaging modalities may be employed.
While RFA was selected due to its wide use in hepatic tumor ablation [16], radioembolization combined with other ablation modalities may be associated with different results.
Alternately, additional neuro-physiological signal modalities may be incorporated for human affective state monitoring, such as fNIRS, galvanic skin response, and eye tracking.
These two modalities may be conceived as separate, but reality is that we continuously move between the two poles in our daily activity.
The amoeboid mode of migration that applies to E. histolytica's displacements on two-dimensional surfaces is also expected to apply to the three-dimensional environment in the human intestine although several unknown, distinct modalities may be involved.
However, the co-registration of structures in sequentially acquired sessions in different imaging modalities may be difficult because, e.g., the carotid artery changes its exact position with the head position and global registration algorithms usually are based on other structures.
Although multiple feature streams from multiple modalities may be integrated and recognized simultaneously (using 'early integration' or 'data-level fusion') [2], as in bimodal audio-visual speech recognition, this approach is only successful when the modalities are well synchronized with each other.
