Abstract: An encoder including circuitry and memory coupled to the circuitry. In both of a first case where an orthogonal transform is performed and a second case where the orthogonal transform is skipped, when a number of CABAC processes is within an allowable range, the circuitry: encodes a plurality of coefficient information flags by CABAC; and encodes a remainder value of the coefficient; and when the number of CABAC processes is not within the allowable range, the circuitry: skips the encoding of the plurality of coefficient information flags, wherein in the first case, the circuitry: converts the coefficient to a second coefficient by using a poszero value that is determined using a plurality of surrounding coefficients; and encodes a value of the second coefficient, and wherein in the second case, the circuitry: encodes the value of the coefficient.

Abstract: A selection method is for selecting a reference message to be used to detect unauthorized communication in an in-vehicle network system including a network and one or more electronic control units connected to the network. The reference message is used as a reference for determining whether a message sent to the network is anomalous. The selection method includes: storing candidate information regarding one or more reference message candidates each being a candidate of the reference message; selecting, based on the candidate information regarding the one or more reference message candidates stored in the storing, the selection method for selecting the reference message from among the one or more reference message candidates; and selecting the reference message from among the one or more reference message candidates using the selection method.

Abstract: An encoder is an encoder that encodes a block in a picture using a prediction image of the block, and includes circuitry and memory. Using the memory, the circuitry: calculates a first average pixel value which is an average pixel value of first reference samples out of the first reference samples and second reference samples, The first reference samples are referable and located outside the block and adjacent to a first side of the block. The second reference samples are referable and located outside the block and adjacent to a second side of the block. When generating the prediction image, the circuitry applies the same prediction pixel value to inner samples among current samples to be processed that are included in the block. The inner samples constitute a quadrilateral region including at least two current samples in each of a horizontal direction and a vertical direction.

Abstract: An encoder includes circuitry and a memory coupled to the circuitry. The circuitry, in operation, determines whether or not a ternary split process of splitting a block into three sub blocks in a first direction parallel to a first longer side of the block is allowed by comparing a size of a second shorter side of the block to a minimum threshold value. The circuitry, responsive to the ternary split process being allowed, writes, into a bitstream, a split direction parameter indicative of a splitting direction. The circuitry, in operation, splits the block into a plurality of sub blocks in a direction indicated by the split direction parameter; and encodes the plurality of sub blocks. The minimum threshold value corresponds to a minimum size supported in a transform process.

Abstract: An encoder includes circuitry and memory coupled to the circuitry. In operation, the circuitry: derives a motion vector of a current block by referring to at least one reference picture different from a picture to which the current block belongs; performs a mode for estimating, for each sub-block unit of sub-blocks obtained by splitting the current block, a surrounding region of the motion vector to correct the motion vector; determines whether to apply deblocking filtering to each of boundaries between neighboring ones of the sub-blocks; and applies the deblocking filtering to the boundary, based on a result of the determination.

Abstract: An encoder includes circuitry and memory connected to the circuitry. In operation, the circuitry: corrects a base motion vector using a correction value for correcting the base motion vector in a predetermined direction; and encodes a current partition to be encoded in an image of a video, using the base motion vector corrected. The correction value is specified by a first parameter and a second parameter, the first parameter indicating a table to be selected from among a plurality of tables each including values, the second parameter indicating one of the values included in the table to be selected indicated by the first parameter. In each of the plurality of tables, a smaller value among the values is assigned a smaller index. Each of the plurality of tables includes a different minimum value among the values.
