Abstract: A determination method for a chroma intra prediction mode includes: performing a simple RDO calculation on a luminance value of each pixel of an image block to obtain multiple luminance candidate modes; determining multiple chroma candidate modes according to one of the luminance candidate modes and a chroma simple RDO result calculated by performing a simple RDO calculation on a chroma value of each pixel of the image block; performing a full RDO calculation of the multiple luminance candidate modes on the luminance value of each pixel in the image block to select a luminance target mode; performing a full RDO calculation of the multiple chroma candidate modes on the chroma value of each pixel of the image block to a obtain chroma full RDO result; and determining a chroma target mode according to the luminance target mode and the chroma full RDO result.

Abstract: Provided is a side wall window structure module of a train, the side wall window structure module comprising a window wallboard (100), supporting members shaped like the Chinese character “” and reinforcing members shaped like the Chinese character “”, and stand columns (210) and supporting cross beams (311, 312, 313, 314) using the supporting members shaped like the Chinese character “”, wherein two flanging edges of each supporting member shaped like the Chinese character “” are fixed on the inner side, facing the interior of the train, of the window wallboard (100); each reinforcing member shaped like the Chinese character “” comprises a longitudinal reinforcing member (220) and a transverse reinforcing member (320); two flanging edges of each reinforcing member shaped like the Chinese character “” are fixed to one side edge of each supporting member shaped like the Chinese character “”; and an arched high edge of each reinforcing member shaped like the Chinese character “” is fixed to the other side edge
