Abstract
An approach is provided for feature point detection and representation. The approach, for example, involves processing (e.g., using a neural network or equivalent) image data associated with a grid cell of an image to determine a feature point corresponding to a position of a feature detected in the image data. The approach also involves encoding the position of the feature with respect to a coordinate system referenced to the grid cell. The output comprises one or more parameters indicating the encoded position, one or more attributes of the feature, or a combination thereof.
Claims20
A method comprising:
- processing image data associated with a grid cell of an image to determine at least one feature point corresponding to a feature detected in the image;
- parametrically encoding a position of the at least one feature point with respect to a coordinate system referenced to the grid cell;
- and
- providing an output to represent the at least one feature point,
- wherein the output includes one or more parameters indicating an encoded position of the at least one feature point, one or more attributes of the feature, or a combination thereof.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
- segment an input image into a plurality of grid cells;
- process image data associated with a grid cell of an image to determine at least one feature point corresponding to a feature detected in the image;
- parametrically encode a position of the at least one feature point with respect to a coordinate system referenced to the grid cell;
- and
- provide an output to represent the at least one feature point,
- wherein the output includes one or more parameters indicating an encoded position of the at least one feature point, one or more attributes of the feature, or a combination thereof.
A non-transitory computer-readable storage medium, carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to perform:
- processing image data associated with a grid cell of an image to determine at least one feature point corresponding to a feature detected in the image;
- parametrically encoding a position of the at least one feature point with respect to a coordinate system referenced to the grid cell;
- and
- providing an output to represent the at least one feature point,
- wherein the output includes one or more parameters indicating an encoded position of the at least one feature point, one or more attributes of the feature, or a combination thereof.
