What is the solution to this error?

What this error main?

.....

>> SSDBExperiment_BuildCropDataset

Error using fullfile (line 67)

All inputs must be strings, character vectors, or cell arrays of character vectors.

Error in SSDBExperiment_BuildCropDataset (line 17)

D.SaveDir = fullfile(D.Root, 'CropData');

.......

I have file with name (fullfile.m)

What should I do, which lines need change to work correctly.

Thank you in advanced.

At the time the error shows up, what is class(D.Root) ?

[Ruwaida Lawgali]

Structure array

[Walter Roberson]

You cannot pass a struct array into fullfile()

Perhaps one of the fields inside D.Root is what you need.

[Ruwaida Lawgali]

D.Root contains 6 images

DefaultRoot=load('DefaultRoot.mat'); %-->DefaultRoot

D.Root =DefaultRoot;

[Walter Roberson]

When you use that form of load(), then the output variable DefaultRoot will be created as a struct vector with one field name for each variable stored in the .mat file.

Your code is not expecting DefaultRoot.mat to contain images: your code is expecting that it will contain a variable named DefaultRoot that is the name of the parent directory of CropData where the data is to be stored.

ResolveMissingOptions() is then used to create options.SaveDir that is what is actually used later.

[Ruwaida Lawgali]

When I put :

D.SaveDir = fullfile('C:\Users\ALSRAYA\Desktop\codes\codeHMAX\Caltech\PNGImages\cars', 'CropData');

instead of :

D.SaveDir = fullfile(D.Root, 'CropData');

it works without errors, and gaves this result:

........

is it correct????

[Walter Roberson]

That looks plausible.

Or you could leave the code the way it was but put in

D.Root = 'C:\Users\ALSRAYA\Desktop\codes\codeHMAX\Caltech\PNGImages\cars';

before D.Root is used.

[Ruwaida Lawgali]

How can I find the next file to be run after the main file???

I have a code with 41 files.

Thank you in advanced

[Walter Roberson]

CAfilelist.mat variable CAfilelist needs to be a cell array . Each element of the cell array must be a struct that contains a field named olistname that is used by QReadOList2 and the result of that Q* call needs to be a struct that contains a field named 'car'

But, options.UsableIndices had to be set first, and options is created by ResolveMissingOptions, which we do not have the source code for, so I do not know if D.Root is used in creating the options.

[Ruwaida Lawgali]

ResolveMissingOptions

[Ruwaida Lawgali]

QReadOList2

[Ruwaida Lawgali]

I have these things.

CAfilelist.mat variable CAfilelist needs to be a cell array .

CAfilelist.mat (1x3547 cell)

...............

Each element of the cell array must be a struct that contains a field named olistname

Anno_OList\SSDB00001_olist.mat ........to n

[Ruwaida Lawgali]

Good evening,

When I run the next file.m(ResolveMissingOptions)

I got this:

requires more input arguments to run.

........

ResolveMissingOptions(options, d)

Undefined function or variable 'options'.

........

What should I put as a defualt (options, d) =(?,?)

Thank you.

[Walter Roberson]

It looks like options.UsableIndices is being set from the assignment

D.UsableIndices = 1:300;

If I read the code correctly, that already tells it to use the first 300 entries from CAfilelist .

I have a code with 41 files.

But your display from CAfilelist shows 3547 ?

[Ruwaida Lawgali]

I mean when I decompressed the code, I found (41 file.m), including (SSDBExperiment_BuildCropDataset).

But

what does this mean:

But your display from CAfilelist shows 3547 ?

Thank you.

[Walter Roberson]

I would suggest consulting the documentation that came with the code.

[Ruwaida Lawgali]

Documentation like what.

[Walter Roberson]

What did you get the software from? Was there no description of it?

I searched for some key function names, but I was not able to find that software anywhere, so I do not know where it is from or how it is intended to be used.

[Ruwaida Lawgali]

Well, maybe I selected an Incomplete code for HMAX.

First of all, I have studied many papers about Object Recognition.

Then, I wanted to make an execute for this subject.

So, I focused on the paper that made the first standard for HMAX(Robust Object Recognition with Cortex-Like Mechanisms)

They said:

"Both the source code of our system and the StreetScenes data set used in our experiments are readily available [16].

[16] A software implementation of the system as well as the StreetScenes data set, http://cbcl.mit.edu/software-datasets , 2006."

I downloaded the code from this site.

So, I just need to execute the HMAX code, Then add a small modification.

This thing is really important for my dissertation.

After all, can you help me to find a complete and correct code for my subject, please.

To make a comparison with other papers, I need to execute the original code, and get the accuracy.

Then, I will add a corner detection to solve the problem that found in Standard HMAX.

Thank you.

[Walter Roberson]

I am not sure which code link you used? When I look at that site they say that HMAX was for a 1999 paper and the MATLAB code is no longer available from them.

[Ruwaida Lawgali]

what do you think of this code ?

is it a standrd?

CBCL <[e-mail]‏>

The following link will be valid for 24 hours:

[Walter Roberson]

It looks like it is layered on top of a different software package, and that most of the computation work is done in C. It looks like the work was done roughly a decade ago.

It is an unusual way of writing code, but it is possible that it fits in well with their other software package.

[Ruwaida Lawgali]

Thank you.

Can I execute it with matlab?

[Walter Roberson]

You would install the CNS package first and then this set of software, and then you would be able to use it from MATLAB. It defines a set of MATLAB classes and methods but does the computation in C for efficiency.
