Abstract
An image processing apparatus is described comprising a processor configured to access a template of image elements. The processor is configured to search an image which is larger than the template to find a region which is similar to the template, where similarity is measured using a similarity metric. The similarity metric comprises a normalized cross correlation function which is modified to include at least one factor related to a statistic of both the template and the region.
Claims20
An image processing apparatus comprising:
- a processor configured to access a template of image elements;
- the processor being configured to search an image which is larger than the template to find a region of the image which is similar to the template, where similarity is measured using a similarity metric;
- and
- wherein the similarity metric comprises a normalized cross correlation function which is modified to include at least one factor related to a statistic of both the template and the region.
A computer-implemented method of template matching comprising:
- receiving a template of image elements;
- searching an image to find a region which is similar to the template, where similarity is measured using a similarity metric;
- wherein the similarity metric comprises a normalized cross correlation function which is modified to include a factor related to a comparison of the region and the template.
One or more tangible device-readable media with device-executable instructions that, when executed by a computing system, direct the computing system to perform operations comprising:
- receiving a template of image elements;
- searching an image to find a region which is similar to the template, where similarity is measured using a similarity metric;
- wherein the similarity metric comprises a normalized cross correlation function which is modified to include at least one factor related to a comparison of the region and the template.
