| 摘要 |
An array of pixel-to-pixel dissimilarity values is analysed to select a pixel which has a low pixel-to-pixel dissimilarity value and which has neighbouring pixels which have a low pixel-to-pixel dissimilarity value. Each pixel-to-pixel dissimilarity value represents a difference between the value of a pixel in a first spatial pixel array representing a first image and the value of a corresponding pixel in a second spatial pixel array representing a second image. The pixels neighbouring the current pixel are divided into at least two polar sectors. The current pixel is selected when the current pixel and the pixels of at least one polar sector have low dissimilarity values. |

1. In a video processor, a method of analysing an array of pixel-to-pixel dissimilarity values to select a pixel which has a low pixel-to-pixel dissimilarity value and which has neighbouring pixels which have a low pixel-to-pixel dissimilarity value; the method comprising the steps of:
receiving a spatial array of pixel-to-pixel dissimilarity values, each pixel-to-pixel dissimilarity value representing a difference between the value of a pixel in a first spatial pixel array representing a first image and the value of a corresponding pixel in a second spatial pixel array representing a second image; dividing the pixels neighbouring the current pixel into at least two polar sectors; and selecting the current pixel when the current pixel and the pixels of at least one polar sector have low dissimilarity values. |
