Abstract: Embodiments of this disclosure provide a coding unit partitioning method, image coding/decoding method and apparatuses thereof. The coding unit partitioning method is by performing down-sampling on a processing unit to be partitioned to obtain a block to be partitioned of a predetermined size; inputting a first vector transformed from the block to be partitioned into a trained neural network model to acquire an output result of the trained neural network model. The output result is a partition probability in a horizontal direction and a partition probability in a vertical direction. The method includes performing a horizontal partition on the processing unit to be partitioned when the partition probability in a horizontal direction is greater than or equal to a threshold, and performing a vertical partition on the processing unit to be partitioned when the partition probability in a vertical direction is greater than or equal to the threshold.

Abstract: Methods and apparatuses for coding and decoding mode information and electronic device. The method for coding includes determining a uniform transform block mode adopted by a coding block of an image; determining a binary bit to which the uniform transform block mode corresponds according to a size of the coding block and/or a determined number of uniform transform block modes; and coding the binary bit to which the uniform transform block mode corresponds into a bit stream of the image. Hence, for example, not only uniform transform block mode information may be coded and decoded, but also bit costs of coding may be lowered.

Abstract: Embodiments of this disclosure provide an apparatus to perform a loop filter function using a convolutional neural network (CNN) and an apparatus to perform image decoding. to perform the loop filter, the apparatus is to perform down sampling on a frame of an input reconstructed image to obtain first feature maps of N channels; perform residual learning on input first feature maps of N channels among the first feature maps to obtain second feature maps of N channels; and perform up sampling on input second feature maps of N channels among the second feature maps to obtain an image of original size of the reconstructed image. Functions of the loop filter are carried out by using CNN, which may reduce a difference between a reconstructed frame and an original frame, reduce an amount of computation, and save processing time of the CNN.

Abstract: A pressurized decanting device decants wine, so that oxidation is prevented by not agitating the wine as it decants, or agitating solid matter resting on the bottom of bottle. The decanting device couples to the mouth of bottle through a cork having a cork borehole. A pump forces pressurized gas into the bottle of wine. The consequential pressure forces the wine out of the bottle through a discharge pipe in the housing. The device includes a base mounted with a housing. The housing includes an outlet apparatus, a pump, a power supply mechanism, and a switch mechanism operatively connected to the pump and the power supply mechanism. An outlet pipe and a gas guiding apparatus extend from the outlet apparatus. The switch mechanism mounts on the outlet apparatus through power supply mechanism.

Abstract: An image coding method and apparatus, as well as an image decoding method and apparatus are provided. The image coding method includes: performing the following processing on each intra-coding unit of an image: determining identification information for identifying a mode, where the mode defines one or more partition schemes, in each of which the intra-coding unit is uniformly partitioned into one or more transform units having a same size, and sizes of the transform units partitioned using different partition schemes are different; partitioning the intra-coding unit into the one or more transform units according to the mode identified by the identification information; and coding the image based on the one or more transform units. With the embodiment of the present disclosure, less bit cost for partition labels of the intra-coding unit is required, image prediction with a higher accuracy acquired, and a high coding efficiency can be achieved.
