Abstract: An approach is provided for machine learning-based registration of imagery with different perspectives. The approach, for example, involves retrieving a first training image and a second training image. The first training image depicts a geographic area from a first perspective and the second training image depicts the geographic area from a second perspective. The approach also involves initiating a labeling of one or more ground truth correspondence masks between the first training image and the second training image. The one or more ground truth correspondence masks denote an image region of the first training image that matches a corresponding image region of the second training image or vice versa. The approach further involves using the one or more ground truth correspondence masks to train a machine learning model to determine one or more predicted correspondence masks between a first input image and a second input image.

Abstract: An approach is provided for spatial aggregation for location based services. The approach involves, for example, determining a plurality of partitions for a geographic area. The approach also involves determining a set of destinations that is common to a first partition and a second partition of the plurality of partitions. The set of destinations are associated with a plurality of trips originating from first partition, the second partition, or a combination thereof. The approach further involves determining a statistical property of the plurality of trips between any of the set of destinations and the first partition, the second partition, or a combination thereof. The approach further involves merging the first partition with the second partition into the traffic analysis zone based on the statistical property.

Abstract: An approach is provided for machine learning-based prediction of an estimated time of arrival (ETA) or any other trip characteristic. The approach involves, for example, receiving a request for an ETA (or any other trip characteristic). The request specifies an origin, a destination, and a time of departure. The approach also involves discretizing the origin to an origin ETA homogenous zone and the destination to a destination ETA homogenous zone. The approach further involves determining one or more features of one or more pre-computed k-shortest paths for an origin-destination (O-D) zone pair comprising the origin ETA homogenous zone and the destination ETA homogenous zone. The approach further involves providing the one or more features as an input to a trained machine learning to predict the ETA of the trip (or any other trip characteristic).
