Method Image.Image()->match()
- Method match
object match(int|float scale, object objectneedle)
object match(int|float scale, object objectneedle, object objecthaystack_cert, object objectneedle_cert)
object match(int|float scale, object objectneedle, object objecthaystack_avoid, object intfoo)
object match(int|float scale, object objectneedle, object objecthaystack_cert, object objectneedle_cert, object objecthaystack_avoid, object intfoo)- Description
-
This method creates an image that describes the match in every pixel in the image and the needle-Image.
new pixel value = sum( my_abs(needle_pixel-haystack_pixel))
The new image only have the red rgb-part set.
- Parameter scale
-
Every pixel is divided with this value. Note that a proper value here depends on the size of the neadle.
- Parameter needle
-
The image to use for the matching.
- Parameter haystack_cert
-
This image should be the same size as the image itselves. A non-white-part of the haystack_cert-image modifies the output by lowering it.
- Parameter needle_cert
-
The same, but for the needle-image.
- Parameter foo
- Parameter haystack_avoid
-
This image should be the same size as the image itselves. If foo is less than the red value in haystack_avoid the corresponding matching-calculating is not calculated. The avoided parts are drawn in the color 0,100,0.
- Returns
-
the new image object
- Note
-
experimental status; may not be exact the same output in later versions
