Undefined function 'imageDataStore' for input arguments of type 'cell'.
显示 更早的评论
Code:
outputFolder = fullfile('C:\Users\JIARA\Documents\MainGUI');
rootFolder = fullfile(outputFolder, 'Eye_Images');
categories = {'Normal','Diabetes Detected'};
imds = imageDataStore(fullfile(rootFolder, categories), 'LabelSource', 'foldernames');
tbl = countEachLabel(imds);
[trainingSet,testSet] = splitEachLabel(imds,0.3,'randomize');
bag = bagOfFeatures(trainingSet);
categoryClassifier = trainImageCategoryClassifier(trainingSet,bag);
confMatrix = evaluate(categoryClassifier,testSet)

imageDataStore is introduced in R2016a. If you are using R2015b or before, you cannot use it and you get the result like "undefined function." If you are using R2014b or later version, use datastore function instead with setting Type option as 'image.'

The class imageDataStore was introduced in R2015b, but the function required R2016a.
