A method for decoding a picture block is disclosed. The decoding method comprises: decoding () at least one stream S_diff into decoded data and into one information for identifying a reconstructed reference picture in a decoder picture buffer; reconstructing () a special reference picture from at least the identified reconstructed reference picture and from the decoded data; reconstructing () the picture block from at least the special reference picture, wherein the at least the special reference picture is not displayed.

Coding and decoding methods of a picture block, corresponding devices and data stream

A method for decoding a picture block is disclosed. The decoding method comprises: —decoding () at least one stream S_diff into decoded data and into one information for identifying a re-constructed reference picture in a decoder picture buffer; —reconstructing () a special reference picture from at least the identified reconstructed reference picture and from the decoded data; —reconstructing () the picture block from at least the special reference picture, wherein the at least the special reference picture is not displayed.

A method for decoding a picture block is disclosed. The decoding method comprises: &#x2014;decoding () at least one stream S_diff into decoded data and into one information for identifying a reconstructed reference picture in a decoder picture buffer; &#x2014;reconstructing () a special reference picture from at least the identified reconstructed reference picture and from the decoded data; &#x2014;reconstructing () the picture block from at least the special reference picture, wherein the at least the special reference picture is not displayed.

A method for decoding a picture block is disclosed. The decoding method comprises:

A method is described for reconstructing a current block of a current image from at least one block of a reconstructed reference image at a different size from the size of the current image. The method comprises the steps:

Method and device for coding an image block, corresponding decoding method and decoding device

A method for encoding an interlaced video comprising a sequence of alternating TOP and BOT fields is disclosed. The method for encoding comprises:

Video encoding/decoding methods, corresponding computer programs and video encoding/decoding devices

A method and a device are described for modifying a video frame for encoding or decoding wherein values of pixels of the video frame are represented an increased bit depth. The described method comprises using processing means for executing the step of offsetting the pixel values of increased bit depth with offsets, the offsets depending on a spatial neighbourhood of the pixel to-be-offset. Such local adaptive offsetting of pixel values de-emphasizes high frequencies in the transform domain artificially emphasized by the bit depth increase.

Method and device for encoding a video frame, method and device for decoding a video frame and storage medium

Detection of the salient points in an image enable the improvement of further steps such as coding or image indexing, watermarking, video quality estimation. The methods rely on the fact that a model is fully based on the human visual system (HVS) such as the computation of early visual features, and the methods compute a saliency map for video images taking into account motion and the velocity of the eye.

Device and method for creating a saliency map of an image

The invention concerns a method for processing images, texture pattern blocks representative of a typical texture of the images being stored in a memory, the method comprising the following steps: The invention also concerns an electronic device for processing the corresponding images.
