Abstract
The invention relates to a method and an apparatus implementing the method. The method comprises extracting region proposals from a media content; selecting a set of region proposals corresponding to an object in the media content; identifying objects of interest; determining an object-specific representation by an iterative tracking method; sampling positive examples from the set of tracked region proposal groups obtained from the iterative tracking method; and performing object segmentation.
Claims20
A method, comprising:
- extracting region proposals from a media content;
- selecting a set of region proposals corresponding to an object in the media content;
- identifying objects of interest;
- determining a confidence map for the extracted region proposals that accounts for a region-wise score and a classification confidence;
- generating another set of region proposals by slicing the confidence map;
- determining an object-specific representation by an iterative tracking method;
- sampling positive examples from the set of tracked region proposal groups obtained from the iterative tracking method;
- and
- performing object segmentation.
An apparatus, comprising at least one processor and at least one memory, said at least one memory stored with a computer program thereon, which when executed by said at least one processor, causes the apparatus to extract region proposals from a media content;
- select a set of region proposals corresponding to an object in the media content;
- identify objects of interest;
- determine a confidence map for the extracted region proposals that accounts for a region-wise score and a classification confidence;
- generate another set of region proposals by slicing the confidence map;
- determine an object-specific representation by an iterative tracking method;
- sample positive examples from the set of tracked region proposal groups obtained from the iterative tracking method;
- and
- perform object segmentation.
A computer program product embodied on a non-transitory computer readable medium, comprising computer program code configured to, when executed on at least one processor, cause an apparatus or a system to:
- extract region proposals from a media content;
- select a set of region proposals corresponding to an object in the media content;
- identify objects of interest;
- determine a confidence map for the extracted region proposals that accounts for a region-wise score and a classification confidence;
- generate another set of region proposals by slicing the confidence map;
- determine an object-specific representation by an iterative tracking method;
- sample positive examples from the set of tracked region proposal groups obtained from the iterative tracking method;
- and
- perform object segmentation.
An apparatus, comprising
- means for extracting region proposals from a media content;
- means for selecting a set of region proposals corresponding to an object in the media content;
- means for identifying objects of interest;
- means for determining a confidence map for the extracted region proposals that accounts for a region-wise score and a classification confidence;
- means for generating another set of region proposals by slicing the confidence map;
- means for determining an object-specific representation by an iterative tracking method;
- means for sampling positive examples from the set of tracked region proposal groups obtained from the iterative tracking method;
- and
- means for performing object segmentation.
