为什么 Scilab 不能打开图像文件？

问题描述

我尝试在 Scilab 下处理图像文件，一开始就卡住了，无法加载图像文件。

我已经搜索了帮助系统以及网络，尝试了两个版本的Scilab（因为我找到的一些答案说6.0与某些图像功能不兼容）仍然画了一个空白。无论我尝试什么，imread 函数都不存在。

这是我得到的：

在 Scilab 6.0.2 下：

--> clear

--> atomsSystemUpdate()
Scanning repository http://atoms.scilab.org/6.0 ... Done


--> atomsInstall("SIVP")
atomsInstallList: The package "SIVP" is not registered.
Please check on the ATOMS repository that it is available for Scilab 6.0 on Windows.
If it is,run atomsSystemUpdate() before trying atomsInstall(..) again.

--> atomsInstall("IPCV")
 ans  =

    []


--> disp( atomsGetInstalled() );

!IPCV  4.1.2  user  SCIHOME\atoms\x64\IPCV\4.1.2  I  !


--> im=imread("Kratka220.tif")

Undefined variable: imread

在 Scilab 5.5.2 下：

-->clear
 
-->atomsSystemUpdate()
Scanning repository http://atoms.scilab.org/5.5 ... Done

 
-->atomsInstall("SIVP")
 ans  =
 
     []
 
-->atomsInstall("IPCV")
atomsInstallList: Pakiet IPCV nie jest dostępny.
<this is Polish for "Package IPCV is not available"; I installed 5.5.2 in Polish>

我做错了什么？

解决方法

atomsInstall 后，您必须重新启动 Scilab 才能加载工具箱。
