Description

The operator create_template_rotcreate_template_rotCreateTemplateRotcreate_template_rotCreateTemplateRotCreateTemplateRot preprocesses a pattern, which is passed as an image, for the template matching. An extension to create_templatecreate_templateCreateTemplatecreate_templateCreateTemplateCreateTemplate the matching can applied to rotated patterns. The parameters AngleStartAngleStartAngleStartAngleStartAngleStartangleStart and AngleExtendAngleExtendAngleExtendAngleExtendAngleExtendangleExtend define the maximum rotation of the pattern: AngleStartAngleStartAngleStartAngleStartAngleStartangleStart specifies the maximum counter clockwise rotation and AngleExtendAngleExtendAngleExtendAngleExtendAngleExtendangleExtend the maximum clockwise rotation relative to this angle. Therefore AngleExtendAngleExtendAngleExtendAngleExtendAngleExtendangleExtend has to be smaller than . With the parameter AngleStepAngleStepAngleStepAngleStepAngleStepangleStep the maximum angle resolution (on the highest resolution level) can be specified.

You have to be aware, that all possible rotations are calculated beforehand to reduce runtime during matching. This leads to a higher execution time for create_template_rotcreate_template_rotCreateTemplateRotcreate_template_rotCreateTemplateRotCreateTemplateRot and high memory requirements for the template. The amount of memory depends on the parameters AngleExtendAngleExtendAngleExtendAngleExtendAngleExtendangleExtend and AngleStepAngleStepAngleStepAngleStepAngleStepangleStep. The number of pyramid levels can be neglected. If A is the number of pixels of TemplateTemplateTemplateTemplateTemplatetemplate, the memory M needed for the template in byte is about:

After the transformation, a number (TemplateIDTemplateIDTemplateIDTemplateIDTemplateIDtemplateID) is assigned to the template for being used in the further process.

A description of the other parameters can be found at the operator create_templatecreate_templateCreateTemplatecreate_templateCreateTemplateCreateTemplate.

Attention

You have to be aware, that depending on the resolution a large number of pre calculated patterns have to be created which might result in a large amount of memory needed.

Parallelization

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
