◆ af_match_template()

AFAPI af_err af_match_template ( af_array out,
const af_array  search_img,
const af_array  template_img,
const af_match_type  m_type 
)

C Interface for image template matching.

Parameters
[out]outwill have disparity values for the window starting at corresponding pixel position
[in]search_imgis an array with image data
[in]template_imgis the template we are looking for in the image
[in]m_typeis metric that should be used to calculate the disparity between window in the image and the template image. It can be one of the values defined by the enum af_match_type
Returns
AF_SUCCESS if disparity metric is computed successfully, otherwise an appropriate error code is returned.
Note
If search_img is 3d array, a batch operation will be performed.

◆ matchTemplate()

AFAPI array af::matchTemplate ( const array searchImg,
const array templateImg,
const matchType  mType = AF_SAD 
)

C++ Interface for image template matching.

Parameters
[in]searchImgis an array with image data
[in]templateImgis the template we are looking for in the image
[in]mTypeis metric that should be used to calculate the disparity between window in the image and the template image. It can be one of the values defined by the enum af_match_type
Returns
array with disparity values for the window starting at corresponding pixel position
Note
If search_img is 3d array, a batch operation will be performed.
