Then call the images one by one (for loop) from the folder and do operation as per requirement.

When I'm doing like imfinfo() shows error msg :

char, string

Instead its type was uint8.

Error in bitdepth2 (line 9)

imfinfo(img)

Hi, from the documentation

https://www.mathworks.com/help/matlab/ref/imfinfo.html

this function takes in a filename and gives you the information about that image. If you pass a folder name, it would give an error which is the standard behavior.

You can use the following command to list directory contents and extract individual file information in a for loop.

Regarding writing the data to excel, you can refer this documentation
