DEVICE AND METHOD OF EXTRACTING ONLY A BOUNDARY AREA SIGNAL BY USING A SPATIAL CORRELATION IN AN IMAGE SIGNAL WHICH IS MIXED WITH A NOISE CAPABLE OF EXTRACTING ONLY A CHARACTERISTIC OF A BOUNDARY PART BY COMPARING A CORRELATION OF A NOISE SIGNAL AND A BOUNDARY PART SIGNAL

摘要

PURPOSE: A device and method of extracting only a boundary area signal by using a spatial correlation in an image signal which is mixed with a noise are provided to effectively extract only a boundary part in an image which has a noise by using a correlation with a neighboring signal.;CONSTITUTION: A signal distribution characteristic is analyzed and a slope by using a signal brightness on a space coordinate in a device extracting only a boundary part on a KxL stop image which a noise is mixed. After extracting the image primarily, an image which noise is finally removed is extracted by calculating and digitalizing the correlation with the noise.;COPYRIGHT KIPO 2011
