COMPUTER IMPLEMENTED METHOD AND SYSTEM FOR DETECTING AN OBJECT MARKED BY MEANS OF STROKE INPUT OF A USER ON THE BASIS OF PIXELS IN A DIGITAL IMAGE

摘要

A user touches a touch sensitive display or otherwise provides input comprising “stroke” gestures to trace areas which are to be the subject of post-processing functions. The stroke area is highlighted and can be added to or corrected by additional stroke and “erase” gestures. Pixel objects are detected proximate to the stroke area, with a precision based on the zoom level. Stroke gesture input may be received and pixel object determination may be performed in series or in parallel.
