- W74486014 abstract "This paper describes an application of Self-Organizing Maps to a telecommunication task, namely the speaker contour detection in videophone images. The problem of contour detection is related to improvements in quality and to the reduction of the information transmitted during a videophone communication. Only the area inside the speaker contour could be coded with a high accuracy, exploiting the immobility of the landscape and its scarce relevance in the image to code it at a lower bit-rate. The speaker contour detection is faced by the combined action of an algorithmic low level image processing, which spots a cloud of pixels scattered around the speaker contour, and of a Self-Organizing Map, which interpolates the points to approximate the contour." @default.
