    Abstract: The present technology relates to an image processing device and an image processing method that are capable of efficiently generating a multi-view image.A setting unit of a non-base encoding unit sets view direction management information for managing a base image of a base view to be stored in a decoded picture buffer when encoding a dependent image of a dependent view. An encoding unit of the non-base encoding unit generates encoded data by encoding the base image and the dependent image. A delivery unit of the non-base encoding unit delivers the view direction management information that is set and the encoded data that is generated. The present technology can be applied to an image processing device that encodes a multi-view image, for example.

    Abstract: The present disclosure relates to an image processing device and method that enable improvement in processing efficiency in encoding or decoding.A type E0 of an LCU 115 and its coefficient are determined on the encoder side. The coefficient of the type E0 was sent to the decoder side at the time of the LCU 111, and has been stored in an EO buffer included in an adaptive offset filter on the decoder side. For the LCU 115, therefore, a copy of the coefficient of the type E0 in the EO buffer is used on decoder side without the sending of the coefficient of the type E0. As described above, the parameters of the adaptive offset filter, which are transmitted in one batch at the beginning of a frame in the related art, are sent sequentially at the beginning of an LCU for each LCU. The present disclosure can be applied to, for example, an image processing device.

    Abstract: There is provided an image processing apparatus and an image processing method that are capable of suppressing an increase in loads when a point cloud is generated from a mesh. Point cloud data is generated by positioning points at intersection points between a surface of a mesh and vectors each including, as a start origin, position coordinates corresponding to a specified resolution. For example, intersection determination is performed between the surface of the mesh and each of the vectors, and in a case where the surface and the vector are determined to intersect each other, the coordinates of the intersection point are calculated. The present disclosure can be applied to an image processing apparatus, electronic equipment, an image processing method, a program, or the like.

    Abstract: The present disclosure relates to information processing apparatus and method that makes it possible to suppress a reduction in encoding efficiency. Information relating to quantization of a three-dimensional position of an encoding target is generated. For example, the information relating to the quantization includes information relating to a coordinate system to be subjected to the quantization, information relating to a bounding box for normalization of position information of the encoding target, or information relating to a voxel for quantization of position information of the encoding target. In addition, three-dimensional information of the encoding target is restored from a signal string on the basis of the information relating to the quantization of the three-dimensional position of the encoding target. The present disclosure is applicable to, for example, an information processing apparatus, an image processing apparatus, an electronic device, an information processing method, a program, or the like.
