Abstract
Official abstract text for this publication.
A method of modifying an annotation input on an interactive display in an interactive input system is described. Reference pixel values in a region of interest of a reference frame are determined. The region of interest is associated with the annotation. The reference pixel values are stored in memory. It is determined whether current pixel values in the region of interest of a current frame differ from the reference pixel values. The annotation is faded if the current pixel values in the region of interest differ from the reference pixel values. A computing device configured to implement the method and a computer-readable medium having stored thereon instruction to implement the method are also described.
First claim
