Abstract
An image processing device includes a dictionary data storage unit to store dictionary data regarding features that a plurality of objects has, an arithmetic unit to compute feature data of an input image based on information of the input image that includes an object with a specific feature among the plurality of objects, and a calculation unit to calculate a parameter for adjusting the dictionary data regarding the object with the specific feature based on the feature data and the dictionary data.
Claims16
An image processing device, comprising:
- a storage unit configured to store dictionary data related to features of a plurality of objects;
- and
- a processor that executes:
- an arithmetic process to compute feature data of an input image based on information of the input image that includes an object with a specific feature among the plurality of objects, the specific feature being a subset of the features of the plurality of objects;
- and
- a calculation process to calculate a parameter for adjusting the dictionary data related to the object with the specific feature based on the feature data and the dictionary data, wherein
- the arithmetic process sets a plurality of areas in the input image and computes the feature data for each of the plurality of the areas by comparing a coefficient value that is obtained by applying wavelet conversion to each of the plurality of areas with a predetermined threshold value;
- the storage unit stores the dictionary data in association with area information related to the plurality of areas;
- and
- the calculation process refers to the storage unit and calculates the parameter for each of the plurality of areas based on the feature data computed by the arithmetic process and the dictionary data.
