| IMP::em2d::PolarResamplingParameters::PolarResamplingParameters | ( | const cv::Mat & | m | ) |
Compute the parameters for a polar resampling getting the dimensions from the matrix
\params[in] matrix Matrix that is going to be resampled
| void IMP::em2d::PolarResamplingParameters::create_maps_for_resampling | ( | ) |
After the number of radius and angles values are set, this function Builds a map of resampling coordinates. This map is very useful for
| double IMP::em2d::PolarResamplingParameters::get_angle_step | ( | ) | const |
get the angular step used
| double IMP::em2d::PolarResamplingParameters::get_ending_radius | ( | ) | const |
Gets the largest radius.
| unsigned int IMP::em2d::PolarResamplingParameters::get_number_of_angles | ( | ) | const |
Gets the number of points that are sampled for the angles remember that this number is usually different to the approximated value that you provide to the function set_estimated_number_of_angles()
| unsigned int IMP::em2d::PolarResamplingParameters::get_number_of_rings | ( | ) | const |
Get the number of rings (that is, the number of radius values considered)
| double IMP::em2d::PolarResamplingParameters::get_radius | ( | unsigned int | n_ring | ) | const |
Gets the current radius employed for the ring in consideration)
| double IMP::em2d::PolarResamplingParameters::get_radius_step | ( | ) | const |
Get the step for the radius coordinate.
| void IMP::em2d::PolarResamplingParameters::get_resampling_map | ( | cv::Mat & | m1 | ) | const |
Obtain the resampling map of type CV_32FC2 (floats, slower that those obtained with get_resampling_maps()
| void IMP::em2d::PolarResamplingParameters::get_resampling_maps | ( | cv::Mat & | m1, |
| cv::Mat & | m2 | ||
| ) | const |
Get the samplings maps of type CV_16SC2 and CV_16UC1 (this map combination is faster for remapping. See OpenCV hel for remap()
| double IMP::em2d::PolarResamplingParameters::get_starting_radius | ( | ) | const |
Gets the initial radius of the resampling.
| void IMP::em2d::PolarResamplingParameters::set_estimated_number_of_angles | ( | unsigned int | aprox_value | ) |
You give an approximated number of values that you want to use for the resampling, and the function computes the optimal number for an FFT based on this approximated number
| void IMP::em2d::PolarResamplingParameters::setup | ( | unsigned int | rows, |
| unsigned int | cols | ||
| ) |
Initalize the internal parameters to generate all the values The class uses a number of radius values for resampling that is optimal to perform FFT during the rotational alignment. The first gess is half the rows and columns
