There are 4 images, and I want to crop them by using coding. But I want to crop one image by using imcrop command and other 3 images should automatically cropped the same place i cropped the image 1. As an example there are

1.bmp,
2.bmp,
3.bmp,
4.bmp,

I want to give cropping parameters to only 1.bmp image and other images will be cropped the same place and view the crop images in a fig format.

You ought to be able to accomplish this with imcrop itself.

First use this:

[I1c rect] = imcrop(I1)

Which returns the cropping rectangle in rect, a four-element position vector.

Then

I2c = imcrop(I2, rect)

Which crops the image I2. rect is a four-element position vector[xmin ymin width height] that specifies the size and position of the crop rectangle obtained from the first image.
