Frame Difference
显示 更早的评论
In the frame difference method,on converting an image to frame,i have got an error in the following statement:
M(i-1)=im2frame(unit8(fg),gray);
fg is gray image.
the error is :
Indexed movie data values must be legal color map indices:
1.0<=value<=length(colormap) for double-precision movie data,and
0<=value<=length(colormap)-1 for unit8 movie data.
plzz tell me how can i fix this error?

The default size of the colormap for gray() is smaller than 256 elements. You need to use
M(i-1)=im2frame(uint8(fg),gray(256));

I have an images (492x510) unit16 and I want to convert images into movies frame using im2frame using the following code:
temp1 = imread('image1.tiff'); % unit16
temp2 = double(temp1);
f(1) = im2frame(temp2,gray(4096));
But I got error:
??? Error using ==> im2frame
double-precision indexed CData values must be legal colormap indices: 1.0 <= value <= length(colormap)

Why are you casting it to double? Don't do that. There's probably a zero in there and it says it must have values between 1 and 4096. Why did you want to cast to double anyway, when it was not necessary?

I am casting it to DOUBLE because im2frame can only make movie frame from image matrices of type double or unit8 and i checked, its not zero.
