Technologies are disclosed for determining a best time to contact a party over a plurality of contact periods of time to achieve at least one of a desired outcome and a desired result. In various embodiments, the party has multiple contact types that can be utilized to contact the party. Accordingly, an optimal contact type for the party for each contact period is selected that identifies the contact type with a probability having the highest likelihood of achieving at least one of the desired outcome and the desired result by utilizing the contact type to contact the party during the contact period. A best time to contact the party is then identified as one of the contact periods based on the optimal contact types selected for the party for each contact period and associated probabilities.

Described is a system for collision detection and avoidance estimation using sub-region based optical flow. During operation, the system estimates time-to-contact (TTC) values for an obstacle in multiple regions-of-interest (ROI) in successive image frames as obtained from a monocular camera. Based on the TTC values, the system detects if there is an imminent obstacle. If there is an imminent obstacle, a path for avoiding the obstacle is determined based on the TTC values in the multiple ROI. Finally, a mobile platform is caused to move in the path as determined to avoid the obstacle.
