I want to use video from following directory
'E:\Multimedia Security\matlab\UCSD_Anomaly_Dataset.v1p2\UCSDped1\Train\Train001'
Following is the code which i wrote
close all
clear all
clc
workingDir = 'E:\Multimedia
Security\matlab\UCSD_Anomaly_Dataset.v1p2\UCSDped1\Train\Train001';
videoofReader = vision.VideoFileReader(dir(fullfile(workingDir, 'abc.avi')));
videoPlayer = vision.VideoPlayer;
while ~isDone(videoofReader)
frame = step(videoofReader);
step(videoPlayer, frame);
end
release(videoofReader);
release(videoPlayer);
Error which i get is
`Error using VideoFileReader.set.Filename (line 139)
Expected Filename to be one of these types:
char
Instead its type was struct.

Error in kl2 (line 18)
videoofReader = vision.VideoFileReader(dir(fullfile(workingDir, 'abc.avi')));
System prompts you Error in kl2 (line 18) so this line has a problem. You do not need to use dir because you already have an absolute path.
Give you two solutions:
videoofReader = vision.VideoFileReader(fullfile(workingDir, 'abc.avi'));
dirstruct = dir(fullfile(workingDir, 'abc.avi'));
videoofReader = vision.VideoFileReader(dirstruct{1});

I'm for now compiling in CPU version.I am working on matlab 2020a.I've tried to remove the vl_nnconv.m from matconvnet but i still get the following error.
Also the matconvnet i'm using is version matconvnet-1.0-beta25 I'm stuck here since 2 days ,could somebody lease help me out with this issue?
https://github.com/XinLi-zn/TADT
The above is the github code i'm trying to work on.
Foloowing are the errors i'm getting:
Error using vl_nnconv
The option name is not a string (argument number 5)
Error in dagnn.Conv/forward (line 11)
outputs{1} = vl_nnconv(...
Error in dagnn.Layer/forwardAdvanced (line 85)
outputs = obj.forward(inputs, {net.params(par).value}) ;
Error in dagnn.DagNN/eval (line 91)
obj.layers(l).block.forwardAdvanced(obj.layers(l)) ;
Error in get_subwindow_feature (line 37)

Error in tadt_tracking (line 63)

Error in Demo_TADT (line 23)
[result, fps]=tadt_tracking(seq_info.img_list, seq_info.gt(1,:), vgg16_model_path, display);
the following are the functions that is causing the error and the argument is obj.pad
function outputs = forward(obj, inputs, params)
if ~obj.hasBias, params{2} = [] ; end
outputs{1} = vl_nnconv(...
inputs{1}, params{1}, params{2}, ...
'pad', obj.pad, ...
'stride', obj.stride, ...
obj.opts{:}) ;
end
I am trying to apply a forward feature selection on a PRdataset. Following the syntax presented online though produces a bunch of errors that I don't quite understand and haven't been able to solve. Any ideas on what is causing them or how to fix?
Code used and resulting errors shown below:
A=prdataset(data,classes);
[w,r]=featself(A,'NN');

Error in featself (line 56)

I have to concatenate the path and file name but the following error is coming as given below:
path = 'E:\Ob_Extraction\peta\PETA dataset\3DPeS\archive\';
allFiles = dir( 'E:\Ob_Extraction\peta\PETA dataset\3DPeS\archive' );
allNames = { allFiles.name };
image = imread(strcat(path,allNames(3)));
Error using imread>parse_inputs (line 457)
The file name or URL argument must be a string.
Error in imread (line 316)
[filename, fmt_s, extraArgs] = parse_inputs(varargin{:});
how do i solve it ?
My code execute correctly for the digits but it given some errors to the characters. the image presented in that location but it shows image not found like..

I want to compile a gui matlab project, but fail because of this error which is not in my code

How can I get matlab (2013b) to compile the package?
The code where matlab fails is (which is NOT my code)
function tf = isscript(files)
% ISSCRIPT Is the file a script file?
tf = false(1,numel(files));
for k=1:numel(files)
pth = files{k};
% Can't be a script if it isn't an M-file.
if strcmpi(pth(end-1:end), '.m') && exist(pth, 'file') == 2
mt = matlab.depfun.internal.cacheMtree(pth);
fcn = mtfind(mt, 'Kind', 'FUNCTION');
tf(k) = isempty(fcn);
end
end
The code will fail for files with a filename of length 1. Either rename all files with such a short filename or change the line to:
if length(pth)>1 && strcmpi(pth(end-1:end), '.m') && exist(pth, 'file') == 2
