Member Function Documentation

bool CMotion2DWarping::backWarp (  short *    src, int    src_nrows, int    src_ncols, short *    dst, CMotion2DModel    model )

Generate a backwarped image in dst from the original image src, using the motion model model. The size of the images to backwarped is given by [src_nrows, src_ncols ]. The size of the backwarped image is to set by calling initBackWarp(). The 2D parametric motion model to use to backwarp the image src is specified by model. Warning: Before using this function, the warping must be initialized by a call to initBackWarp(). Warning: The table containing the compensated image dst must be allocated before a call to this function. Return true if success, false otherwise. See also: initBackWarp()

bool CMotion2DWarping::backWarp (  unsigned char *    src, int    src_nrows, int    src_ncols, unsigned char *    dst, CMotion2DModel    model )

Generate a backwarped image in dst from the original image src, using the motion model model. The size of the images to backwarped is given by [src_nrows, src_ncols ]. The size of the backwarped image is to set by calling initBackWarp(). The 2D parametric motion model to use to backwarp the image src is specified by model. Warning: Before using this function, the warping must be initialized by a call to initBackWarp(). Warning: The table containing the compensated image dst must be allocated before a call to this function. Return true if success, false otherwise. See also: initBackWarp() Examples: Motion2D.cpp.

void CMotion2DWarping::getBackWarpPosition (  int    row, int    col, float &    d_row, float &    d_col )

Gives the cumulated displacements of a pixel which position is defined by row, col, with respect to the reference image specified by initBackWarp(). The cumulated displacement along the row axis is stored in d_row, along the column axis in d_cols. See also: initBackWarp(), backWarp()

bool CMotion2DWarping::initBackWarp (  int    dst_nrows, int    dst_ncols, int    dst_row_offset, int    dst_col_offset )

This function allocates the memory necessary to store the combination of the instantaneous motion displacements between two successive images and defines the reference image which respect to the motion compensation is performed. The size of the images to compensate is given by [src_nrows, src_ncols]. The size of the motion compensated image computed by warp() or backWarp() is given by [dst_nrows, dst_ncols]. His size can be greater than the image size. The parameters dst_row_offset and dst_col_offset, specify the position of the reference image in the motion compensated image. The considered origin is the upper-left corner of the source image. return true if the warping initialization succeed, false otherwise. See also: warp(), backWarp() Examples: Motion2D.cpp.

bool CMotion2DWarping::warp (  unsigned char *    src, unsigned char *    dst, int    nrows, int    ncols, CMotion2DModel    model )

Warp the image src into dst using the motion model model. The parameter nrows refers to the number of lines in the images. ncols indicates the number of columns. Warning: The table containing the warped image dst must be allocated before a call to this function. Return true if success, false otherwise. See also: CMotion2DModel Examples: Warping.cpp.
