    摘要： An aspect of present principles is directed to methods, apparatus, systems and computer readable media for image processing. The image processing may include receiving a standard dynamic range (SDR) image or a receiver for receiving a standard dynamic range (SDR) image. It may further include determining an over-exposed region of the SDR image and determining a corrected luminance value for at least a pixel of the over-exposed region, or a processor configured to determine an over-exposed region of the SDR image and a corrected luminance value for at least a pixel of the over-exposed region. The corrected luminance value is determined based on at least one of a shape of the over-exposed region, luminance information of pixels surrounding the over-exposed region, and edge information of the pixels surrounding the over-exposed region. The over-exposed region may be an irregularly shaped region.

    摘要： A method for enhancing quality of an image comprises deriving from an initial low-resolution image (LRI) an initial high-resolution image (IHRI) by upsampling (S2, S3), providing (S4), based on the initial low-resolution image (LRI), at least one downsampled filtered image (AIij, AIi′j′) with lower resolution, providing (S6), based on the initial low-resolution image (LRI), an unfiltered image (LRI, UIi′j′) having same resolution as the downsampled filtered image, selecting a patch (PI) from the initial high-resolution image (IHRI), finding (S8) filial patches (PA k) similar to the selected patch in the downsampled filtered image (AIij, AIi′j′), finding, in the unfiltered image (LRI, UIi′j′), parent patches (PPk) locally associated to the filial patches (PAk), and linearly combining (S14) the parent patches (PPk) to form an enhanced quality patch (EP). Finally, enhanced quality patches (EP) obtained by repeatedly carrying out above steps are combined (S15) to form an enhanced quality high-resolution image (EIp).

    摘要： A method and apparatus for dynamic range expansion of an LDR video sequence are suggested. The suggested method comprises the steps of: acquiring the LDR video sequence and at least one HDR panoramas concurrently, an image in said HDR encompassing a wider field of view than an image in said LDR; determining a dynamic range expansion operator based on the LDR video sequence and the HDR panoramas; and applying the determined dynamic range expansion operator on the LDR video sequence.

    摘要： A method for decoding a scalable stream comprising a base layer and at least one enhancement layer is described. The method includes: reconstructing at least one image from the base layer, decoding a first part of the enhancement layer relating to a group of blocks into decoded enhancement data which comprise at least one item of information for identifying at least one region of the reconstructed at least one image, processing the region of the reconstructed at least one image identified by the information, obtaining residues for at least one block of the group of blocks from a second part of the enhancement layer, and reconstructing the blocks of the group from residues and from the region processed.
