+It creates a Gabor filter with the specified wavelength (in pixels/cycle) and orientation (in degrees). If you specify wavelength or orientation as vectors, gabor returns an array of gabor objects, called a filter bank, that contain all the unique combinations of wavelength and orientation. For example, if wavelength is a vector of length 2 and orientation is a vector of length 3, then the output array is a vector of length 6.

+//
+// Parameters
+// maxBits : Logarithm to the base 2 of maximal shift in each dimension. Values of 5 and 6 are usually good enough (31 and 63 pixels shift respectively). Value should not exceed 6. It is of Double type.

+// Parameters
+// srcImg1 : It is the first input image.
+// srcImg2 : It is the second input image, which is also the target image.

+// rpTPS : It is used to set the regularization parameter for relaxing the exact interpolation requirements of the TPS algorithm. It is of double type.
+// sfAffine : It is used to set the full-affine condition for Affine Transformation. If true, the function finds as optimal transformation with no additional restrictions(6 degrees of freedom).
