Abstract: Example implementations include a method of locating landmarks at a target object model by obtaining a target model associated with a target physical object, and a reference model associated with a reference physical object and including an anchor landmark coordinate, generating a convergence metric based on a structural property of the target model at the anchor landmark coordinate, a structural property of the reference model at the landmark coordinate, and an alignment resolution associated with a first quantized distance, and in accordance with a determination that the convergence metric satisfies a convergence heuristic and does not satisfy a resolution heuristic, associating the alignment resolution with a second quantized distance less than the first quantized distance, and modifying a position of the anchor landmark coordinate based on the alignment resolution.

Abstract: Systems and methods are disclosed which employ a centralized selection context having selection states spread across user interface elements. Methods are described in which the binding between widgets and data storage is isolated using the centralized selection context paradigm for a majority of data items represented within a user interface. This selection context is fully accessible by methods that access data while considering the current selection context. The centralized selection context simplifies event-handling logic by having selection context readily available thus removing the need to query individual widgets for their state.

Abstract: A method performed at a computer system having one or more processors and memory storing one or more programs for execution by the one or more processors is disclosed. The method includes accessing multiple images of a biological structure, generating an electrical property map of at least a portion of the biological structure in accordance with two or more of the multiple images, and providing at least a subset of the electrical property map.

Abstract: Apparatuses, systems, methods, and program products are disclosed for targeted electrical stimulation. A method includes determining, by a processor, a base configuration for each of a plurality of electrodes configured to transmit an electrical current towards a target area of a biological structure. A method includes calculating a cost associated with transmitting an electrical current to the target area according to the base configuration. A method includes modifying the base configuration in response to the calculated cost not satisfying a minimum cost threshold. The modified configuration clusters electrical current transmitted by each of the electrodes at the target area according to a resistivity map of the biological structure to minimize the cost of transmitting the electrical current. The cost is re-calculated according to the modified configuration and the configuration is modified until the minimum cost threshold is satisfied.
