Could not LoadSamples

[TrueBlue10]

Hello @jwyang ,
I'm trying to run your matlab code on my machine now. But I met some issue when I tried to load the image in.
in the test_model file, after I ran the code "te_data = loadsamples(imgpathlistfile, 1);"
the data returned is always "Empty cell array: 0-by-1";
Could you please provide me some information on it?
Thank you

Hi, @TrueBlue10

I think it could be caused by the incorrect format of 'imgpathlistfile'? It should be cell data, looks like {'lfw'} or so. Did you use the same format?

Thanks for your information.I'm using {'afw'} as my testing database. Because of some unknown reason, the command Data = cell(length(imgpathlist), 1); always create an 0*1 cell.
I split the code into lgh = length(imgpathlist); Data = cell(lgh, 1);
it could create a 377 * 1 cell now.

But new error comes. when I run img = im2uint8(imread(imgpathlist{i}));the im2uint8 function always give me an exceptions says that 未定义与 'uint8' 类型的输入参数相对应的函数 'im2uint8'。(undefined function for im2uint8 using uint8 as variable)(loadsamples (line 22)).
I thought this was because imread(imgpathlist{i}) was already in uint8. so I just remove im2uint8 function. But it will give me an error afterwards shows 未定义与 'double' 类型的输入参数相对应的函数 'fitgeotrans'。 in code Data{i}.tf2meanshape{1} = fitgeotrans(bsxfun(@minus, Data{i}.intermediate_shapes{1}(1:end,:, 1), mean(Data{i}.intermediate_shapes{1}(1:end,:, 1))), ... (test_model (line 114))which means the data I load is in double format.
It's really confused to me now. My word is a little messy. Please let me know if I didnt explain myself clearly.
Really appreciate for your help.

Hi, @TrueBlue10 ,

as mentioned in the readme file, *fitgeotrans * command may not be supported for soime versions of matlab, I think you may need to do following alternations:

fitgeotrans -> cp2tform, transformPointsForward -> tformfwd

Hello @jwyang,
Unfortunately, changing the function didnt solve the problem. I'm using Matlab R2015b. I'll keep digging what happen on my machine.
thank you.
