A system and method for segmenting foreground and background regions on a digitized image uses a computer, having a processor and system memory, to segment the image into initial regions and identify background regions from the initial regions. The VVM application includes an option to create a voicemail password. The time between the pulse and a reference point of the signal waveform from the terminals of the generator is used to calculate the power angle of the generator. The apparatus may include an anchoring groove disposed at the first mandrel end, and an anchoring device being configured and located to urge the first preform end towards the anchoring groove to secure the first preform end therebetween. The controller supplies the number of drive pulses calculated based on a target position for moving the lens calculated based on the output from the operation unit and a lens position detected by the position detection unit. On the other hand, if the number of the candidate lines does not reach the predetermined number, the threshold is changed to a low value so as to facilitate the extraction of the edge points.
