Morphologic transformation is used to smoothly transform one image to another. An almost textbook example of this sort of transformation is shown in a popular videoclip, Black Or White by Michael Jackson, where the faces of different people change one into another. From a user viewpoint, this transformation can be described as a point-to-point and area-to-area transition of one image into another. For example, when one face transforms to another face, one should set the transition of the nose to nose, the left eye to left eye, the outline of the initial face to the outline of the destination face and so on. In HiJaak Morph, points and lines are used to set the transition of points and areas. That is, you should select points and contours (lines) in the source image that will be transformed to new points and contours in the destination image. In the example with faces mentioned above the procedure would be the following. You select points in the centers of the eyes in the source face and move them to the centers of eyes in the destination image. You repeat the procedure for other important points, lip corners, etc. You select the contour of the face in the source image and move it in the target image so that it fits the outline of the target face. The more points and lines you select, the better and smoother is the effect, but it will also take more time to complete the transformation. The algorithm of morphologic transformation used in HiJaak Morph guarantees that every selected point or line in the source image will be transformed to its selected counterpart in the target image. In the areas of the image where no points or lines had been selected, the transformation will work in the smoothest possible way.
