| 英文摘要 | The local variance of image intensity is a typical measure of image smoothness. It has been extensively used, for example, to measure the visual saliency or to adjust the filtering strength in image processing and analysis. However, to the best of our knowledge, no analytical work has been reported about the effect ofJPEG compression on image local variance. In this paper, a theoretical analysis on the variation of localvariance caused by JPEG compression is presented. First, the expectation of intensity variance of 8x8 non-overlapping blocks in a JPEG image is derived. The expectation is determined by the Laplacian parametersof the discrete cosine transform coefficient distributions of the original image and the quantization step sizes used in the JPEG compression. Second, some interesting properties that describe the behavior of the localvariance under different degrees of JPEG compression are discussed. Finally, both the simulation and theexperiments are performed to verify our derivation and discussion. The theoretical analysis presented in this paper provides some new insights into the behavior of local variance under JPEG compression. Moreover, it has the potential to be used in some areas of image processing and analysis, such as image enhancement,image quality assessment, and image filtering. |
