Hello, i am trying to do an rcnn tutorial, https://www.mathworks.com/help/vision/examples/object-detection-using-deep-learning.html using my data set and options, but after i finish training i cant test the rcnn.
This is the error
Error using imread>get_full_filename (line 568)
File "image_01964.jpg" does not exist.
Error in imread (line 377)
fullname = get_full_filename(filename);
Error in roi (line 26)
testImage = imread('image_01964.jpg');
And i am using this for reading the image i want to test.
testImage = imread('image_01964.jpg');
% Detect stop signs
[bboxes,score,label] = detect(rcnn,testImage,'MiniBatchSize',128)
The files are all in same folder, i made sure the name is correct.

It's much safer and easier to use full file paths for data you are loading rather than assume it is in the current directory (which, usually, is not an ideal place for data to live anyway)

Hi, I'm facing this same problem but I do not understand the suggestion here. Can you explain further? Thanks.

If you are only providing a filename:
A = imread('mypicture.jpg');
then mypicture.jpg must exist on the MATLAB search path or in the current working directory. If the file isn't in any of the places that MATLAB is already looking for files, then it obviously won't find it.
Either you have to ensure that the file is on the search path, or in the current directory as Kalyan suggests, or as Adam suggests above, you need to specify the full path and filename.
fpath = '/data/path/to/mybigpileofpictures/';
fname = 'mypicture.jpg';
A = imread(fullfile(fpath,fname));
