Tony S Yu f21f032bfe Add normalization test and remove unnecessary clipping. 2012-05-08 21:32:07 -04:00
Tony S Yu 94262bc8d6 Tweak example to reduce confusion.
Set background 1 so that the template has values equally-above and -below the mean image value. This change makes the template results left-right symmetric, which may reduce confusion.

Tony S Yu 5682d27eb0 Rewrite normalization algorithm.
This is a major revision that removes the `method` parameter of `match_template` and uses a new normalization method.

Note that the example result is different with this new normalization.

Tony S Yu 753e999a7a Minor cleanup

* Delete some old comments.
* Move some variable initializations to the top of the function.

Tony S Yu 545bdab985 Refactor template matching.
* Change Cython function to take names of correlation method instead of numbers representing the methods.

* Use alternate formula for `template_norm` of 'norm-corr' method, but note that both formulas need to be checked for correctness.

* Add note that `match_template` output has a different shape than the input image. This needs to be fixed before merging.

* Change 'Sigma' to 'Sum' in docstring to avoid confusion with standard deviation.

* Other minor changes for readability.

Tony S Yu 9d3072d3f8 Fix type errors in match_template by casting inputs to float32. 2012-05-08 21:32:06 -04:00
Tony S Yu 2a00e24b12 Change _template.match_template variables to float.
Template and image in test are converted to float32 before passing to `match_template`. This change is temporary: `match_template` should convert these variables internally.

Tony S Yu 6272c312c4 Simplify _template.pyx using integral_image from transform subpackage.
Remove `integral_images` and `integral_image_sqr` from _template.pyx in favor of calls to `skimage.transform.integral_image`.

This change required `match_template` arguments ("image" and "template") to be changed from float to double.

After this change, the template test runs about 25% slower.
