ANALYZING AN IMAGE SHOWING EDITING MARKS TO OBTAIN CATEGORY OF EDITING OPERATION

摘要

Input image data define an input image set that shows a graphical featureand editing marks indicating an editing operation to be performed on thegraphical feature. The input image data are used to obtain operationcategory data indicating whether the editing operation would translate thegraphical feature so that it is centered at a different position within theinput image set. The operation category data are used to obtain outputimage data defining an output image that includes an edited version of theinput image set. The output image shows the graphical feature centered at adifferent position only if the operation category data so indicate. The inputimage set can include an original image showing the graphical feature andan overlay image showing the editing marks. The editing marks can form anode-link structure with the graphical feature. If the structure is a directedgraph, it can indicate an editing operation that would translate thegraphical feature to be centered at a different position, such as a simpletranslation to a new position, a translation with scaling or rotation, or areplacement operation. If the structure is an undirected graph, it canindicate an editing operation that would not translate the graphical feature,such as a delete operation or a scale or rotate operation. A rectangle with adot inside it can indicate scaling or rotation. A cross can indicate deletion.
