•MorphingDerived from the word metamorphosis.•Metamorphosis
Metamorphosis means to change shapeappearance or form.

What is morphing?
Morphing can be defined as:
- Transition from one object to another.
- Process of transforming one image into
another.
An animation technique that allows you to
blend two still images, creating a sequence of
in – between pictures that when played in
Quick Time, metamorphoses the first image
into the second.

Steps Involved:
• The morph process consists of :-
1) Warping two images so that they have the same
“shape’’.
2) Cross dissolving the resulting images .

W RPING
• A warp is a 2-D geometric transformationand generates a distorted image when it isapplied to an image.
• Warping an image means : apply a givendeformation to it.
• Two ways to warp an image:- Forward mapping. Reverse mapping.

Forward Mapping
• Each pixel in source image is mapped to anappropriate
pixel in destination image.
• Some pixels in the destination image may
not be mapped.

Reverse Mapping
• This method goes through each pixel in thedestination image and samples an appropriate
source image pixel.
• All destination image pixels are mapped to
some source image pixel.
• This mapping is used in the Beier/Neely linemorphing method.

Morphing Process
• Step I : Interpolating the lines: Interpolate the coordinates of the end pointsof every pair of lines.
•
Step II : Warping the Images Each of the source images has to be deformed
towards the needed frame.
The deformation works pixel by pixel is basedon the reverse mapping. This algorithm is calledBeier-Neely Algorithm.

PPLIC TIONS OF MORPHINGUsed to produce special effects in entertainment
industry. Example : Michael Jackson’s Black or whitemusic video.

Morphing Effect in Flash
Macromedia Flash is known as one of the greatest animation tools around. Using the
Flash authoring tool you can create:
• Frame-by-frame Animations• Motion Tweened Animation• Morphing Animation

motion-tweened animations which are
created by specifying the first and the
last frames only, and dynamic
animations that are generated via
Action Script.

In morphing animations which you specifythe first and the final shapes so that all the
frames in between are created by the
authoring tool. This is called Shape Tween.
