Methods for determining a prediction value, an encoder and a decoder are provided. A bitstream is parsed to obtain a size and a coding mode of a current block. Reconstructed values of neighboring samples are acquired and the reconstructed values of the neighboring samples are filtered. A second constant value is calculated according to a bit depth value of a luma component of a sample in the current block. A difference between the second constant value and a first reference value in the reference value set is assigned as a first prediction input value in a prediction input value set. Other prediction input values in the prediction input value set other than the first prediction input value are determined. Prediction values of samples at specific positions in the current block are calculated. The prediction values are filtered to obtain prediction values of all samples in the current block.

Method for determining prediction value and decoder

Provided are a picture encoding and decoding method, an encoder, a decoder and a storage medium. The decoder decodes a bitstream to obtain a size, a coding mode, and residuals of a current block; when the coding mode of the current block is an MIP mode, calculates a second offset based on the size of the current block, a first offset and reconstructed values of adjacent pixels corresponding to the current block; determines a first prediction value of the current block according to the second offset; and determines a reconstructed value of the current block based on the first prediction value.

Image coding/decoding method, coder, decoder, and storage medium

Methods for determining a prediction value, an encoder, and a decoder are provided. Reconstructed values of neighboring samples of a current block are acquired, and then filtered to obtain a reference value set of the current block. When a size of the current block is smaller than a preset threshold value, a first constant value is calculated according to a bit depth value of a luma component of a sample in the current block. A difference between the first constant value and a first reference value in the reference value set is determined as a first prediction input value in a prediction input value set. Other prediction input values in the prediction input value set other than the first prediction input value are determined according to the reference value set. Prediction values of samples at specific positions in the current block is calculated and then filtered.

This invention provides preparations and applications of a highly strong and tough photo-crosslinked hydrogel material. The hydrogel materials are made from the o-nitrobenzyl phototriggers modified photosensitive polymer derivative, double bond groups modified polymer derivative, and photoinitiator. This invention significantly improved the properties of hydrogels by controlling the average molecular weight (arm length) of photosensitive poly (ethylene glycol) (with o-nitrobenzyl phototriggers modification) and its derivatives, and the molar ratio of o-nitrobenzyl phototriggers to poly (ethylene glycol) and its derivatives. Compared with prior technologies, the strength and/or toughness of the hydrogels in this invention are increased by one order of magnitude or even higher. These advances solve the problems of weak mechanical properties in current hydrogel materials and widen the applications of hydrogel materials.

Highly strong and tough photo-crosslinked hydrogel material and its preparation and application

Embodiments of the present disclosure disclose an information processing method, a server, and a non-volatile storage medium. The method includes obtaining first log information in a first time period and then obtaining, based on the first log information, terminal information of a terminal that performs a hit behavior on a media information display place. The method includes determining, based on the terminal information, regional information corresponding to the terminal, where the regional information is used to indicate a region in which the terminal is located. The method also includes determining whether the number of regions in which the terminal is located is greater than a first threshold in a preset time range according to the regional information. The method further includes, when the number is greater than the first threshold, obtaining first terminal information of the terminal and determining that the terminal is an abnormal terminal.

Provided are a picture encoding and decoding method, an encoder, a decoder and a storage medium. The decoder decodes a bitstream to obtain a size, a coding mode, and residuals of a current block; when the coding mode of the current block is an MIP mode, calculates a second offset based on the size of the current block, a first offset and reconstructed values of adjacent pixels corresponding to the current block; calculates a second prediction value of a pixel at a preset position in the current block by using the second offset, the preset position being a particular position in the current block; performs filtering on the second prediction value to obtain first prediction values of all pixels in the current block; and calculates sum values of the first prediction values and the residuals, and sets the sum values as reconstructed values of the current block.
