Abstract
A method of determining a saliency map (e.g., 900) for an input image (e.g., 600) is disclosed. Pre-determined data defining relative salience of image features is accessed. The input image (600) is decomposed according to the predetermined data to identify features of the input image (600) corresponding to the image features in the predetermined data. A portion of the predetermined data corresponding to a range of the identified image features is selected. A perceptual scale is determined using the selected portion of the predetermined data. The saliency map (900) for the input image using the determined perceptual scale.
Claims10
A method of determining a saliency map for an input image, said method comprising:
- accessing pre-determined data defining relative salience of image features;
- decomposing the input image according to the predetermined data to identify features of the input image corresponding to the image features in the predetermined data;
- selecting a portion of the predetermined data corresponding to a range of the identified image features;
- determining a perceptual scale using the selected portion of the predetermined data;
- and
- determining the saliency map for the input image using the determined perceptual scale.
An apparatus for determining a saliency map for an input image, said apparatus comprising:
- means for accessing pre-determined data defining relative salience of image features;
- means for decomposing the input image according to the predetermined data to identify features of the input image corresponding to the image features in the predetermined data;
- means for selecting a portion of the predetermined data corresponding to a range of the identified image features;
- means for determining a perceptual scale using the selected portion of the predetermined data;
- and
- means for determining the saliency map for the input image using the determined perceptual scale.
A system for determining a saliency map for an input image, said system comprising:
- a memory for storing data and a computer program;
- a processor coupled to said memory for executing said computer program, said computer program comprising instructions for:
- accessing pre-determined data defining relative salience of image features;
- decomposing the input image according to the predetermined data to identify features of the input image corresponding to the image features in the predetermined data;
- selecting a portion of the predetermined data corresponding to a range of the identified image features;
- determining a perceptual scale using the selected portion of the predetermined data;
- and
- determining the saliency map for the input image using the determined perceptual scale.
A computer readable medium having a computer program stored thereon for determining a saliency map for an input image, said program comprising:
- code for accessing pre-determined data defining relative salience of image features;
- code for decomposing the input image according to the predetermined data to identify features of the input image corresponding to the image features in the predetermined data;
- code for selecting a portion of the predetermined data corresponding to a range of the identified image features;
- code for determining a perceptual scale using the selected portion of the predetermined data;
- and
- code for determining the saliency map for the input image using the determined perceptual scale.
