select_grayvalues_from_channels(MultichannelImage, IndexImage : Selected : : )

描述

算子 select_grayvalues_from_channelsselect_grayvalues_from_channelsSelectGrayvaluesFromChannelsSelectGrayvaluesFromChannelsSelectGrayvaluesFromChannelsselect_grayvalues_from_channels selects gray values from the different channels of MultichannelImageMultichannelImageMultichannelImageMultichannelImagemultichannelImagemultichannel_image. The channel number for each pixel is determined from the corresponding pixel value in IndexImageIndexImageIndexImageIndexImageindexImageindex_image. Note, IndexImageIndexImageIndexImageIndexImageindexImageindex_image is allowed to have an arbitrary number of channels for reasons of backward compatibility, but only the first channel is considered.

参数

MultichannelImageMultichannelImageMultichannelImageMultichannelImagemultichannelImagemultichannel_image (输入对象) (multichannel-)image(-array) → object (byte)

Multi-channel gray value image.

IndexImageIndexImageIndexImageIndexImageindexImageindex_image (输入对象) singlechannelimage(-array) → object (byte)

Image, where pixel values are interpreted as channel index.

元素数量： IndexImage == MultichannelImage || IndexImage == 1
