摘要： The invention relates to image block encoding and decoding. More precisely, the invention relates to block prediction using reference blocks of the image. It is proposed a method which comprises using processing means for using at least the block for determining one reference block in an already encoded part of the image, encoding and reconstructing a part of the image, using at least the block for determining one reference block in the reconstructed part and a vector referencing the one reference block, using the one reference block for determining at least one further reference block in the reconstructed part and encoding the determined vector and a residual of the block with respect to a combination of the one and the at least one further reference block. Using the block for determination of the one reference block allows for selecting it such that it resembles the block and correlation with the block is maintained.

摘要： For gaze-controlled text size control of a display, the invention proposes to probe, sample and record a user's horizontal gaze Signal; to subject the gaze Signal to a subband filterbank or wavelet transform; to detect line delimiters in the gaze Signal; to derive a reading speed; to determine, as a number of saccades per text line the number of locations where the gaze Signal has sudden high slope portions surrounded on both sides by portions of markedly smaller slope; to detect, based on the reading speed and the number of saccades, a too small font size Status or a too big font size Status; and to initiate a corresponding font size change. Parts of this method can be used for gaze-based measuring of text reading speed and for gaze-based measuring of number of saccades.
