cv.warpPerspective - MATLAB File Help
cv.warpPerspective

Applies a perspective transformation to an image

dst = cv.warpPerspective(src, M)
dst = cv.warpPerspective(src, M, 'OptionName',optionValue, ...)

Input

Output

Options

The function cv.warpPerspective transforms the source image using the specified matrix:

dst(x,y) = src((M_11*x + M_12*y + M_13) / (M_31*x + M_32*y + M_33),
               (M_21*x + M_22*y + M_23) / (M_31*x + M_32*y + M_33))

when the WarpInverse option is true. Otherwise, the transformation is first inverted with cv.invert and then put in the formula above instead of M.
