Abstract
A framework for identifying landmarks in an image. The framework includes multiple agents, each agent being a functional module designed for seeking a predefined home-landmark and a number of further landmarks in a landmark-region around a position of the agent. Each agent defines or receives its start-position, estimates a home-displacement of its home-landmark, estimates vote-displacements of further landmarks in the landmark-region, and chooses an updated start-position. The updated start-position is determined from the estimated home-displacement and the vote-displacements for this home-landmark estimated by other agents.
Claims20
A system for identifying landmarks in an image, comprising:
- one or more processing units;
- and
- a non-transitory memory device communicatively coupled to the one or more processing units, the non-transitory memory device stores computer readable program code, the one or more processing units being operative with the computer readable program code to perform steps including:
- a) defining or receiving, by an agent, a start-position,
- b) estimating, by the agent, a home-displacement for a home-landmark,
- c) estimating, by the agent, vote-displacements for further landmarks in a landmark-region,
- d) choosing, by the agent, an updated start-position, determined from the home-displacement and vote-displacements for the home-landmark estimated by other agents, and
- e) repeating steps b) to d) with the updated start-position as start-position until a termination condition is reached.
A method for identifying landmarks in an image, comprising:
- providing image-data;
- forwarding datasets of the image-data to agents, wherein each agent at least receives a landmark-region of the image-data as dataset;
- and
- processing, by the agents, the datasets, including
- a) defining or receiving, by at least one of the agents, a start-position,
- b) estimating, by the at least one of the agents, a home-displacement for a home-landmark,
- c) estimating, by the at least one of the agents, vote-displacements for further landmarks in the landmark-region,
- d) choosing, by the at least one of the agents, an updated start-position determined from the home-displacement and vote-displacements for the home-landmark estimated by other agents, and
- e) repeating steps b) to d) with the updated start-position as start-position until a termination condition is reached.
One or more non-transitory computer-readable media embodying instructions executable by machine to perform operations for identifying landmarks in an image, comprising:
- a) defining or receiving, by an agent, a start-position,
- b) estimating, by the agent, a home-displacement for a home-landmark,
- c) estimating, by the agent, vote-displacements for further landmarks in a landmark-region,
- d) choosing, by the agent, an updated start-position, determined from the home-displacement and vote-displacements for the home-landmark estimated by other agents, and
- e) repeating steps b) to d) with the updated start-position as start-position until a termination condition is reached.
