Hi, I am trying to train matlab with positive and negative instances of a set of images. But, when i run the script it's say this:
Warning: Name is nonexistent or not a directory: C:\Program
Files\MATLAB\MATLAB Production
Server\R2015a\toolbox\vision\visiondata\data_total
> In path (line 109)
In addpath (line 86)
In Ipositivas (line 4)
Index exceeds matrix dimensions.
Error in Ipositivas (line 6)
negativeImages = negative(negativeFolder);
This is the code I am running:
load('data_total.mat');
positiveInstances = positiveInstances(:,1:2);
imDir = fullfile(matlabroot,'toolbox','vision','visiondata','data_total');
addpath(imDir);
negativeFolder = fullfile('Users','Raedalex','Desktop','MATLAB','Tesis','negative');
negativeImages = negative(negativeFolder);
trainCascadeObjectDetector('TubesDetector.xml',positiveInstances, ...
negativeFolder,'FalseAlarmRate',0.1,'NumCascadeStages',5);

It looks like the folder does not exist. And it looks like data_total is the name of a mat file, not a subfolder of "C:\Program Files\MATLAB\MATLAB Production Server\R2015a\toolbox\vision\visiondata"
Try this:
imDir = fullfile(matlabroot,'toolbox','vision','visiondata');
Also, do you have the Computer Vision System Toolbox installed? What does your "ver" command report?

It sounds as if negative is an array. but negativeFolder is a string, so you are trying to index an array at a string. For that statement to be valid then negative would have to be a function name or a function handle.
