A Total Variation-Based JPEG Decompression Model
We propose a variational model for artifact-free JPEG decompression. It bases on the minimization of the total variation (TV) over the convex set U of all possible source images associated with given JPEG data. The general case where U represents a pointwise restriction with respect to a Lorthonormal basis is considered. Analysis of the infinite dimensional model is presented, including the der...
متن کاملArtifact-free JPEG Decompression with Total Generalized Variation
We propose a new model for the improved reconstruction of JPEG (Joint Photographic Experts Group) images. Given a JPEG compressed image, our method first determines the set of possible source images and then specifically chooses one of these source images satisfying additional regularity properties. This is realized by employing the recently introduced Total Generalized Variation (TGV) as regul...
متن کاملDequantization Bias for JPEG Decompression
Standard JPEG decompression reconstructs quantized DCT coefficients to the center of the quantization bin. This fails to exploit the nonuniform distribution of the AC coefficients. Assuming a Laplacian distribution, we derive a maximum likelihood estimate of the Laplacian parameter, based on the quantized coefficients available at the decoder, and use this estimate to optimally bias the reconst...
متن کاملDecompression Of Corrupt JPEG 2000 Codestreams
In this paper, we investigate the error resilience properties of JPEG2000. Through a careful analysis of the structure of JPEG2000 codestreams, we identify the dependencies among coding passes of a codeblock. In our analysis, we consider the effects of mode variations provided by the standard for low-memory, low-complexity implementations. The proposed methods are derived using the existing dep...
متن کاملArtifact-Free Decompression and Zooming of JPEG Compressed Images with Total Generalized Variation
We propose a new model for the improved reconstruction and zooming of JPEG (Joint Photographic Experts Group) images. In the reconstruction process, given a JPEG compressed image, our method first determines the set of possible source images and then specifically chooses one of these source images satisfying additional regularity properties. This is realized by employing the recently introduced...
