Read entire contents of a file into a string.

Returns the dim'th component of the idx'th point in the class:

* Builds the index */

Helper accessor to the dataset points:

Must return the number of data points

Per-point RMSE between a flat row-major matrix and a vnl_matrix reference.

Count non-overlapping occurrences of needle in content.

Small 2-D point sets used across multiple tests.

Frees the previously-built index. Automatically called within * buildIndex(). */

* Find all the neighbors to \a query_point[0:dim-1] within a maximum radius. * The output is given as a vector of pairs, of which the first elemen

Apply 2D rigid: out[i] = pts[i] * R.T + [tx, ty]. Matches RigidRegistration::PerformTransform with params=[tx, ty, theta].

Return the double that follows `"key": ` in content.

Read optimization parameters from [GMMREG_OPT] section of an INI file. Mirrors Base::MultiScaleOptions: parse all tokens then truncate to level.

* Called during search to add an element matching the criteria. * @return true if the search should be continued, false if the results are * suf

* Create a tree node that subdivides the list of vecs from vind[first] * to vind[last]. The routine is called recursively on each sublist. *
