access_channelaccess_channelAccessChannelAccessChannelaccess_channel (算子名称)

名称

access_channelaccess_channelAccessChannelAccessChannelaccess_channel — 访问多通道图像的一个通道。

参数签名

access_channel(MultiChannelImage : Image : Channel : )

描述

该算子 access_channelaccess_channelAccessChannelAccessChannelAccessChannelaccess_channel accesses a channel of the (multi-channel) input image. The result is a one-channel image. The definition domain of the input is adopted. The channels are numbered from 1 to n. The number of channels can be determined via 该算子 count_channelscount_channelsCountChannelsCountChannelsCountChannelscount_channels.

运行信息
