与im2frame函数相关的错误

Question

我正在尝试将一系列图像写入视频。我得到了以下错误：

In VideoWriter.VideoWriter>VideoWriter.close at 307
  In VideoWriter.VideoWriter>VideoWriter.delete at 256


Error using im2frame
Indexed movie data values must be legal colormap indices:
1.0 <= value <= length(colormap) for double-precision movie data, and 0 <=
value <= length(colormap)-1 for uint8 movie data

Error in VideoStabilization1 (line 134)
   writeVideo(writerObj,im2frame(I,cmap));

我该如何解决它？

我使用下面的代码行来编写视频：

 writeVideo(writerObj,im2frame(I,cmap));

I是一个彩色图像。

Answer 1

它是彩色视频，rgb的像素强度在0-250的平均范围内
