how to read images in MATLAB when images are saved in one folder in the form of image(1),image(2)........image(2000).

Answer 1

string(sprintfc('image(%d).jpg',(1:10)).')

Thats a nice one - but hard for people who have less knowledge than you to work with undocumented functions:

>> which sprintfc
built-in (undocumented)

[madhan ravi]

Thanks for pointing that out then this should do it:

compose("image(%d).jpg", (1:10).')

[Stephan]

Note that:

compose("C:\users\projects\images\image(%04d).jpg", (1:10).')

leads to:

Error using compose
Escaped character '\u' is not valid. See 'doc sprintf' for supported special
characters.

In the case of full path names use:

compose("C:\\users\\projects\\images\\image(%04d).jpg", (1:10).')

to avoid this.

Hi,

you can use numberedFileNameArray from FEX. Here is an example how to use it:

names = numberedFileNameArray(1,5,'C:\user\projects\image\image(1).jpg','1')'

This results in:

names = 

  5×1 string array

    "C:\user\projects\image\image(1).jpg"
    "C:\user\projects\image\image(2).jpg"
    "C:\user\projects\image\image(3).jpg"
    "C:\user\projects\image\image(4).jpg"
    "C:\user\projects\image\image(5).jpg"

You can iterate through this string array and perform your operations on every image for example by a loop or a vectorized operation.

Best regards

Stephan
