homwarp

Warp image by an homography

out = homwarp(H, im, options) is a warp of the image im obtained by applying the homography H to the coordinates of every input pixel.

[out,offs] = homwarp(H, im, options) as above but offs is the offset of the warped tile out with respect to the origin of im.

Options

'full'	output image contains all the warped pixels, but its position with respect to the input image is given by the second return value OFFS.
'extrapval', V	set unmapped pixels to this value (default NaN)
'roi', R	output image contains the specified ROI in the input image
'scale', S	scale the output by this factor
'dimension', D	ensure output image is DxD
'size', S	size of output image S=[W,H]
'coords', {U,V}	coordinate matrices for im, each same size as im.

The edges of the resulting output image will in general not be be vertical and horizontal lines.
