== Transforming Images ==

== Background ==

The transformation process can be thought of as transforming according to the equation 

''New = Original + Percent_Transform*(Destination - Source)''

Where New, Original, Source and Destination are images or templates. 

== Preparation ==

Load the image and template files according to Table 1.

''Table 1 Showing where to load images and templates for transformations.''


||'''Image or Template'''||'''Window Frame'''||
||Original||Transform||
||Source||Psychomorph Left||
||Destination||Psychomorph Right||


Select the Percent_Transform parameters for the shape, colour and texture components separately using the sliders of the same name on the Transform window. Next select the Transform Options from the File menu, which can include any combination of shape, colour, a number of texture options (texture transforming or copying in intensity or RGB), intensity normalisation (matches the brightness of the prototype faces to the subject, requires a mask file), masking of the changes to certain face regions (requires a mask file), and the shape, colour and texture PCA checking options (require additional data). The transformed shape can be previewed by ticking the 'Shape preview' option. 

== Tranforming an image ==

After setting up the images correctly, perform the transformation by selecting 'Transform Image' from the Transform menu and then save the new image and template.

The last transform performed can be undone by selecting 'Undo' from the 'Transform' menu.
