A New Approach for Restoring Block-Transform Coded Images with Estimation of Correlation Matrices
نویسندگان
چکیده
This paper presents a new restoration approach to reduce coding artifacts in block-transform image coding. Digerent from conventional restoration techniques, the proposed one is non-iterative and requires light computational cost, yet can reconstruct objectively and subjectively better images. This good performance is achieved because of the following advantages the proposed approach has: (i) eficient incorporation of the solution bound into restoration; and (ii) effective exploitation of local image properties and statistical knowledge about the quantizers used.

Reduction of Block-Transform Image Coding Artifacts by Using Local Statistics of Transform Coefficie - IEEE Signal Processing Letters
This letter presents a new approach to reduce coding artifacts in transform image coding. We approach the problem in an estimation of each transform coefficient from its quantized version with its local mean and variance. The proposed method can reduce much coding artifacts of low bit-rate coded images, and at the same time guarantee that the resulting images satisfies the quantization error co...

متن کاملEigenvalues-based LSB steganalysis
So far, various components of image characteristics have been used for steganalysis, including the histogram characteristic function, adjacent colors distribution, and sample pair analysis. However, some certain steganography methods have been proposed that can thwart some analysis approaches through managing the embedding patterns. In this regard, the present paper is intended to introduce a n...

In this paper a new very low bit rate video coding scheme is presented. It is based on a forward motion estimation technique using an image warping model, thus delivering the basis for temporal tracking of regions or objects. In order to deal with new or disappearing image contents a new algorithm for the adaptation of a tracked control grid is proposed. correlation of motion vectors may be exp...

The purpose of multi-focus image fusion is gathering the essential information and the focused parts from the input multi-focus images into a single image. These multi-focus images are captured with different depths of focus of cameras. A lot of multi-focus image fusion techniques have been introduced using considering the focus measurement in the spatial domain. However, the multi-focus image ...
