Remap

error in can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.

Right-click the error in control on the front panel and select Explain Error or Explain Warning from the shortcut menu for more information about the error.

Source image.

Destination image. It has the same size as map1 and the same type as src .

The first map of either (x,y) points or just x values having the type CV_16SC2 , CV_32FC1, or CV_32FC2. See convertMaps for details on converting a floating point representation to fixed-point for speed.

Pixel extrapolation method (see BorderTypes). When borderMode=BORDER_TRANSPARENT, it means that the pixels in the destination image that corresponds to the "outliers" in the source image are not modified by the function.

BORDER_CONSTANT = 0, !< `iiiiii|abcdefgh|iiiiiii` with some specified `i`

BORDER_REPLICATE = 1, `aaaaaa|abcdefgh|hhhhhhh`

BORDER_REFLECT = 2, `fedcba|abcdefgh|hgfedcb`

BORDER_WRAP = 3, `cdefgh|abcdefgh|abcdefg`

BORDER_REFLECT_101 = 4, `gfedcb|abcdefgh|gfedcba`

BORDER_TRANSPARENT = 5, `uvwxyz|abcdefgh|ijklmno` - Treats outliers as transparent.

BORDER_ISOLATED = 16 Interpolation restricted within the ROI boundaries.

Value used in case of a constant border. By default, it is 0.

Interpolation method (see InterpolationFlags). The methods INTER_AREA INTER_LINEAR_EXACT and INTER_NEAREST_EXACT are not supported by this function. The extra flag WARP_RELATIVE_MAP can be ORed to the interpolation method (e.g. INTER_LINEAR | WARP_RELATIVE_MAP)

INTER_NEAREST: nearest neighbor interpolation

INTER_LINEAR: bilinear interpolation

INTER_CUBIC: bicubic interpolation

INTER_AREA: resampling using pixel area relation. It may be a preferred method for image decimation, as it gives moire'-free results. But when the image is zoomed, it is similar to the

INTER_NEAREST method.

INTER_LANCZOS4: Lanczos interpolation over 8x8 neighborhood

INTER_LINEAR_EXACT: Bit exact bilinear interpolation

INTER_NEAREST_EXACT: Bit exact nearest neighbor interpolation. This will produce same results as the nearest neighbor method in PIL, scikit-image or Matlab.

INTER_MAX: mask for interpolation codes

WARP_FILL_OUTLIERS: flag, fills all of the destination image pixels. If some of them correspond to outliers in the source image, they are set to zero

WARP_INVERSE_MAP: flag, inverse transformation

WARP_RELATIVE_MAP

The second map of y values having the type CV_16UC1, CV_32FC1, or none (empty map if map1 is (x,y) points), respectively.
