    摘要: An encoding device, a decoding device, and a method for mesh decoding are disclosed. The method for mesh decoding includes receiving a bitstream. The method also includes decoding a frame that includes pixels from the bitstream. A portion of the pixels of the frame represent geometric locations of vertices of a 3D mesh that are organized into overlapped patches. The method further includes decoding connectivity information from the bitstream. Additionally, the method includes identifying triangles associated with the overlapped patches. The triangles represented in an overlapped patch of the overlapped patches are allocated to a projection direction based on a normal vector associated with each of the triangles of the overlapped patch. The method also includes reconstructing the 3D mesh based on the connectivity information and the overlapped patches.

    摘要: A touch sensor of multi-driving scheme includes a touch panel including input lines and output lines, the touch panel causes a change in mutual capacitance in response to touch. Processing circuitry generates transmission signals to the input lines as a result of an encoding operation on a first matrix having an inverse matrix, each of the transmission signals has a first polarity or a second polarity opposite in phase to the first polarity; outputs the transmission signals in an unbalanced period when the sum of phases of the transmission signals is greater than 0; receives receiving signals through the output lines; and decodes the receiving signals based on the first matrix, the receiving signals generated by the change in the mutual capacitance in response to the touch.
