名称

select_grayvalues_from_channelsselect_grayvalues_from_channelsSelectGrayvaluesFromChannelsSelectGrayvaluesFromChannelsselect_grayvalues_from_channels — Selection of gray values of a multi-channel image using an index image.

参数签名

select_grayvalues_from_channels(MultichannelImage, IndexImage : Selected : : )

描述

该算子 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.

运行信息

多线程类型:可重入(与非独占操作符并行运行)。
多线程作用域:全局(可以从任何线程调用)。
在元组级别自动并行化。
Automatically parallelized on domain level.

参数表

MultichannelImageMultichannelImageMultichannelImageMultichannelImagemultichannelImagemultichannel_image (input_object) (multichannel-)image(-array) → object (byte)

Multi-channel gray value image.

IndexImageIndexImageIndexImageIndexImageindexImageindex_image (input_object) singlechannelimage(-array) → object (byte)

Image, where pixel values are interpreted as channel index.

Number of elements: IndexImage == MultichannelImage || IndexImage == 1

Resulting image.

Example (C++ (HALCON 5.0-10.0))

compose3(Focus0,Focus1,Focus2,&MultiFocus);
depth_from_focus(MultiFocus,&Depth,&Confidence,'highpass','next_maximum');
mean_image(Depth,&Smooth,15,15);
select_grayvalues_from_channels(MultiChannel,Smooth,SharpImage);
