Device and method for analysing images by calculating the variance for each pixel of a high-frequency image |
摘要 |
A method and device for analysing video images by obtaining high frequency components. The device includes means for obtaining high-frequency components of a video image and means for obtaining a high-frequency image on the basis of the high-frequency components. Means for calculating the variance for each pixel of the high-frequency image. Means for associating a coefficient with each pixel of the video image as a function of the variance. The coefficient is representative of the visual sensitivity of each pixel for the human eye. The invention relates to a method and a device for analysing video images.
