摘要： A quantization apparatus includes: an imaging unit that converts statistical data at a position in a real space into a pixel value of a coordinate, which is associated with the position, in an image; and a derivation unit that derives a quantization parameter corresponding to a quantization width of the pixel value for each of one or more positions in the real space with respect to a part or a whole of the image. The quantization apparatus may further include a purpose acquisition unit that acquires information indicating a purpose related to statistics. The derivation unit may derive the quantization parameter corresponding to the quantization width that is larger as the pixel value is larger.

摘要： The computational complexity when a block configuration in an encoding target region is determined is reduced while the degradation of coding efficiency is suppressed. A video encoding apparatus includes a block selecting unit which selects each of blocks obtained by recursively dividing an encoding target block as a target block in a predetermined sequence, a block size acquiring unit which acquires the smallest block size in an adjacent block for the selected target block, an evaluation value calculating unit which calculates an evaluation value of the target block if a block size of the target block matches any one of the acquired block size, the block size one level higher than the acquired block size, and the block size one level lower than the acquired block size, and a block configuration determining unit which determines a combination of the blocks constituting the region within the encoding target block based on the evaluation value.

摘要： An encoding apparatus encodes an input image and includes: a provisional encoded data acquisition unit configured to obtain provisional encoded data which has a size greater than a target size of encoded data which is data obtained by encoding the image based on the image and a parameter for determining the target size; and an encoded data acquisition unit configured to obtain the encoded data by converting data within a data range outside of a data range corresponding to the target size in the provisional encoded data into a predetermined value. The provisional encoded data acquisition unit obtains the provisional encoded data so that features for determining the image are contained more within the data range corresponding to the target size than in the data range outside of the data range corresponding to the target size.

摘要： An image processing apparatus for performing correction for each frame group including a predetermined number of frames into which video data is divided includes a decoding unit configured to obtain a corrected frame group by correcting a second frame group, which is a frame group continuous with a first frame group in time, using a feature quantity of the first frame group. The decoding unit performs the correction so that subjective image quality based on a relationship between the second frame group and a frame group subsequent to the second frame group in time is increased and so that a predetermined classifier classifies that a frame group in which the second frame group is concatenated with the frame group subsequent to the second frame group in time is the same as a frame group in which the corrected frame group is concatenated with a corrected frame group obtained by correcting the frame group subsequent to the second frame group in time.
