mkdir(outDirectory);
for i=1:length(Images)

How to retrieve images from this database

[KALYAN ACHARJYA]

Yes, the first line is call the images from folder.

The code details:

Call the images from folder and convert to binary and save the binary image in different folder (with same image file name)

Error using rgb2gray>parse_inputs (line 81) MAP must be a mX3 array

Error in rgb2gray (line 35) X= parse_inputs(varargin{:});

Error in P1 (line 5) ImgName=rgb2gray(ImgName);

I am getting this error

#Edited Answer Check

Are you sure your input images are RGB? May be your images are gray image, therefore skip the line.

Please do share complete code /replication code/sample images?
